Let’s Muddy the Waters, Shall We?

So far I’ve gone over how the loop sling works, and have tried my best to give y’all an idea of how well it assists with precision in a few positions.  The nice thing to me about the loop sling is that because of how simply it functions, it’s easy to get an idea of how it might be employed most advantageously.

The loop sling is not the only way that people attempt to use slings to aid their marksmanship.  The hasty sling is relatively popular to use in standing, and the ‘tactical’ sling is gaining popularity in all sorts of positions.  The mechanisms that these methods use to enhance hitting ability has been less clear to me, and the claimed benefits have, in some instances (not all), seemed to me to be dubious.  I think that some folks thing that if you just wrap sumpin’ round the arm a time ‘r two, it’s bound te dubble accercy ‘tleast.

First Things First

I haven’t quite finished up with the loop sling.  “Why is that,” you might ask, “and why re-introduce it here and now?”  Well speaking of dubious claims… the issue is that I don’t think the loop sling is of benefit in the standing position.  I don’t use it and I don’t recommend it.

The fact that slings aren’t allowed in several forms of competition in which the standing position is used would lead me on its face to believe that the sling should be beneficial.  If it’s cheating, after all, shouldn’t it be more effective?  That alone keeps me barely open to the possibility that to some people it may be helpful.

What I have noticed, however, and several times, mind you, is that people who shoot well in standing are generally current or former competitive shooters.  In non-competitive settings where the only rules are safety rules, these shooters still don’t use slings in standing.  Hmmm.  This is what I have heard from them several times when they are instructing people in the standing position: “You should use a sling in standing because it will help steady your hold.  I don’t use one, but that’s just a bad habit I have from competing because of the way the rules are set up.”  Really???

Breaking the Surface

I don’t want to make this article too long, but I don’t want to leave you completely hanging.  Since I’ve done a bunch of no sling versus loop sling comparisons let’s start there.  I can sum up my disdain of the loop sling in standing by saying that because the support elbow is not supported the shoulder must still support the rifle’s weight, and the benefit of the loop sling is largely negated.

The following groups were shot with my Noveske uppered Mega lowered AR that I’ve been using to experiment various things.  Since it’s still experimental, I call it the X-15.  It currently wears the SWFA SS 3-9×42 with the old school mildot reticle, my prototype RS-3 sling, and I’m using ball ammo equivalent for the following groups.

Standing without sling:

Standing with loop sling:

Loop Sling Standing

In case you were interested I also shot using the more target oriented position without the sling as well:

Target Standing

Using the sling places constraints on the form of the position.  Normally I have my elbow ‘out’ and my support hand well forward of the sling stud.  With a loop sling that really doesn’t work, so I had to approximate how I would have my arm in the prone position.  I also needed more stock in my shoulder pocket in order to handle the rearward tension, which placed the rifle lower.  Because the rifle was lower I needed to lower my head to it.

My arc of movement was large and uncontrollable.  The easiest way to convey what the position with the sling felt like was that it reminded me exactly what it felt like to shoot in standing when I was a brand new shooter.  I was contorted into an awkward, uncomfortable position with my neck craned and my head hanging down to find the sight.  Since I couldn’t control anything or keep the rifle on the target, I was pretty much just trying to jerk a shot as the sight swung by.  Horrible.

Also, the loop sling position lacked pretty much any of the attributes that make standing useful for what it is in the field.  It was slow.  My ability to see my surroundings was severely compromised.  It was unnatural.  It was inflexible.  If I really needed to make the position more stable and had more time, the “target standing” position without the sling will do a bit better as far as precision, and will allow me to maintain a comfortable, balanced position.  The only thing I can say in defense of using the loop sling in standing is that I’m not at all used to using it.  Maybe someone who is used to it could do much better.

‘Target’ Standing: 5.459 MOA

In the next installment we’ll introduce the loop sling’s stepbrother Hasty and later their high speed low drag cousin Tac.

Sling vs. No Sling, Part 3: Kneeling

When I did my position testing last fall, kneeling was a big failure because I had a clean miss of my full sized sheet of paper at 100 yards that invalidated my results on my slow fire group (but strangely, not on my time stress or exerted groups).  Because of that, and also because my kneeling group has a likely effective range of between 30 and 60 yards on my 4” target depending on the acceptable hit rate, I decided to place the target at 50 yards.  It was foggy that day, so 50 yards was about maximum anyway.

Because of the role that kneeling fulfills in the shooter’s toolbox, it probably makes more sense to train on it without the sling.  It’s a fast, relatively imprecise position.  Looping up in kneeling is much like using the standing position as a target shooting stance.  It’s a little bit like trying to use an ambulance as a racecar.  Therefore dressing kneeling up to be accurate through use of a sling seems counterproductive.  Unlike standing, however, the support elbow does have something to set on in the kneeling position, which allows kneeling to benefit fully from the loop sling.  With a sufficiently fast and easy to use sling, such as the Ching sling or my RifleCraft slings, the loop can be donned as the body drops into the position, so it really doesn’t take too much time unless you are really in a hurry.

I fired two groups on the same day with the same ammunition.  As before, I used my FN for this comparison, shooting out of a single lot of Black Hills loaded 155 grain Amax bullets with a muzzle velocity of approximately 2684 fps.  The rifle weighs in at 15.0 pounds unloaded and balances at the front of the magazine.

Without Sling:

Kneeling No Sling

With Sling:

Kneeling Loop Sling

The wide right shot on the group without the sling was the first shot from that position, and was more of a timing issue that I blame on being caused from transitioning from the Noveske to the FN.  I’ve been thinking a lot about timing the shot after my recent intensive standing work, and I want to write about that soon.  Regardless, the bad shot happened and I’m obligated to count it.

The extreme spread of the group without the sling was 178% as large as the group with the sling.  The extreme spread of the no sling group was 8.622 MOA and the group with the sling was 4.826 MOA.

The mean radius of the group without the sling was 123% as large as the sling group.  The mean radius of the no sling group was 2.174 MOA and the mean radius of the group with the sling was 1.766 MOA.

I did not evaluate the time it took to get these shots off, which probably is a meaningful thing to look at.  My guess is that the first shot with the sling is going to be comparatively slow due to the time to sling up and find that perfect natural point of aim.  Follow up shots with the sling are likely to be quicker, as the rifle is steadier.

So far I think I can say that there is compelling evidence to support the contention that the loop sling improves precision in positions other than standing.  I cannot give a number for how much improvement there is, because it seems to be heavily dependent on variables.  I my own work I saw anywhere from the non-sling group being 203% as large as the sling group to the opposite end of the spectrum of the non-sling group being 83% as large as the sling group.  Which variables?  Probably rifle weight, baseline precision of the rifle in question, the shooting position, and the skill of the shooter.

As always, I suggest that you check this out for yourself.

 

Sling vs. No Sling, Part 2: Sitting

You may recall from my last article that shooting prone without a rest or sling to aid me was extremely difficult for me.  My groups were much worse.  My experience in sitting was quite different than my experience in prone without the sling.  My sitting position tended to support itself much better, and was qualitatively much closer to my experience with the sling than the sling vs. no sling in prone.

My clothing was messing with both the sling and non-sling sitting positions.  In particular I was wearing very warm boots that I bought for when I need to be outside and not moving around much.  The thickness of the boots was unfamiliar, and the snow didn’t seem to offer as much of a solid pad for optimum lateral stability.

Shooting without the sling demanded more of me than shooting with the sling.  I had to time the release of the shot more carefully, and I had to be more aggressive on the trigger to make it happen at the right moment.  My recent work in the standing position was very helpful in this regard.

Results below:

With Sling:

1-4-15 Cross Ankle Sitting with Sling
I was pleasantly surprised to see six of the shots in such a nice, tight cluster.  Incidentally, this is a bit better than my group in the same position in October.

 

Without Sling:

Cross Ankle Sitting no sling 1-4-15 FN

 

The extreme spread of the non-sling group was 38% larger than the sling group.  The mean radius of the non-sling group was 67% larger than the sling group.  The disparity between the numbers is because most of the sling groups were grouped in a tight cluster right at the point of aim, and the extreme spread number only counts the worst two shots.

As with prone, shooting without the sling was more physically demanding.  That, coupled with a normal length shooting session in cold weather, had me a bit worn out by the end.  I experienced a strange phenomenon in which my trigger finger was getting passive.  The “auto fire” seemed to have shut down, and I would see a perfectly good sight picture come and go without the gun firing.  In fact, I actually felt my shoulder buck instead of the shot firing in one instance, near the end.  You can also see that one shot went pretty horribly askew.

The First Experiment:

In December, in the midst of all my standing work, I tried the sling/no sling experiment with my AR in cross ankle sitting.  I got different results!

With Sling:

Sitting with sling

Without Sling:

Sitting without sling

In this case, the extreme spread of my sling group was 20% larger than my non sling group.  The mean radius of the sling group was 14% larger than the non-sling group.  I was more than a little shocked by that result.

What it means to me is that there is probably a continuum of how much a sling will actually help that depends on a few things.  The weight of the rifle is probably pertinent. The Noveske is much lighter than the FN.

I believe that the intrinsic precision of the rifle matters, as the sling will not squeeze blood from a rock.  In other words, if the rifle’s absolute baseline group size is larger than the difference between the shooter’s absolute level of precision in the sling and non-sling group,random dispersion could cancel out any ability to clearly see the difference between the two.  It was that aspect of the groups that convinced me to use the FN, so I could see the results with more precision.

Related to the above, I also believe that the more skill the shooter has, the more he can make do with less.  After I had practiced standing for two months, getting into a steadier position and using the same skills of deliberately steadying the hold, timing the shot to coincide with an acceptable sight picture and applying a high degree of follow through made it possible for me to use skill to compensate to a degree for the lack of a sling, especially in a rifle that isn’t so precise as to let me see the exact differences.  I think that a few years ago my non-sling group likely would have been significantly worse under exactly the same conditions with the same equipment.

Of course there is more than one way to skin a cat, such as a sitting position that uses no sling and beats the above conventional seated position, sling or no sling.  I’ve also done this experiment in standing, and hopefully I’ll be able to get kneeling in as well before the month is over.

How Does the Shooting Sling Work? Part 1: Prone

As in, “How well does it work?”  Continuing with the theme from recent posts, this article will only address the loop sling.

I have been using shooting slings to steady my aim in various positions for several years now.  Since the first time I used it I have always been sure that using a sling steadies me except in the standing position.  Since I have been using a sling, I really haven’t shot much without something to steady me up, be it a sling or some kind of support.  Why not use it if it helps?

It’s been so long since I’ve shot groups without a sling that I really don’t know how much it helps.  Honestly, although I fully believe it helps to the point of surety, I could not prove that it does or give an idea of how much.  I like to know things like this, so I decided to check.

Keep in mind that when viewing the following groups that I don’t pretend to be a valid sample size that will be relevant to the general population of rifle shooters.  I’m just one guy who shoots, and these results really only pertain to me.  You’ll have to find out for yourself if they pertain to you.

So far I have shot comparison groups of ten shots each in prone, sitting (cross ankle), and standing with and without the loop sling.  I regularly shoot with a sling in sitting, sometimes in prone, and never in standing because I don’t think it helps.

The Prone Position:

I don’t know how long it had been since I tried shooting in prone without a sling.  I typically use a bipod or try to find some support.  I used my FN PBR-XP with a McMillan A5 stock and Bartlien barrel (.308 Winchester) for this comparison, shooting out of a single lot of Black Hills loaded 155 grain Amax bullets with a muzzle velocity of approximately 2684 fps.  It still is wearing the Vortex Razor HD 5-20×50.  The rifle weighs in at 15.0 pounds unloaded, although I suspect that it might me a tick heavier with cartridges in it.  It balances at the front of the magazine.  I also shot a bipod group for a reference.

Range conditions were:

Prone- No Sling 1-4-15 FN

The numbers turn out like this:

Prone results chart

In comparing the bipod group with the sling group, the sling group was obviously larger in both measures.  The sling groups extreme spread was 19% larger than the bipod group.  The mean radius of the sling group was approximately 29% larger than the bipod group.  To be honest, I was surprised that so many of the shots were hitting so close to the target center with the sling.  It wasn’t until shot 9 that the group really opened up, and until that point I was wondering if I really do shoot better with the sling than with the bipod, as has been the case of late more often than not with the X15.

Without the sling I was in for a surprise.  After shooting it I don’t feel as though I was prepared for the difficulty of the challenge.  The first thing I noticed was that my natural point of aim was way different without the sling.  My body angle tended to be much more straight back.  It was also physically demanding.

The extreme spread of the non-sling group was 204% as large as the sling group.  The mean radius of the non-sling group was 259% as large as the sling group.  This represents the best case scenario for the non-sling group, as I had some doubts as to which hole in the target belonged to which shot.  In this case I would have been better off using a single target and shooting it 10 times, versus what I did, which works better when several bullet holes are on top of each other.

I was out of breath by the end of five shots (I shot 5, got up, loaded a mag, rested, then shot the next 5).  The rifle was heavy and it shook a lot.  I think that a lighter rifle would be easier to shoot, and would probably not exhibit so much more dispersion in comparison to the sling group.  I had to be quite aggressive on the trigger in order to get my shots off near intended point of aim.  My elbow did not seem to belong directly under the rifle as it would with the sling.  Instead my elbows were ‘bipoded’ out under the weight of the rifle, and they became progressively more so as I continued shooting.  You can see from the target that there were some questions about which shot belonged to which target.  The composite above represents a best case scenario, for a conservative comparison with the sling group.

I was not prepared for the impact that the lack of the sling had on my bolt work.  It’s much harder to work the bolt with the relative lack of resistance.  The sling simply keeps the rifle locked in and resistant to movement.  Without the sling, sometimes the movement of pushing the bolt closed was enough to unsettle the position.  There were a few instances in which the rifle would slide forward as I was closing the bolt, which made it tougher to close.

Next up will be the sitting position.

How Does Sling Design Affect Ease of Use?

A ton.

The last article provided my opinion, borne out by testing in the field, that any loop sling will produce results downrange similar to that of any other loop sling in terms of precision.  I have to leave out dedicated competition gear from the discussion because I have no opinion to offer there.  So what, then, is the difference between one sling and the next?

There are a few attributes in slings that define what a sling is best for.  The attributes I can think of at the moment are reliability, durability, loop stability, comfort, adjustability, and rapidity (ease) of looping up.  Some of these tend to be directly related, such as reliability and durability.  Others are generally inversely related, such as reliability versus ease of adjustment, illustrating that every design is a tradeoff intended to fulfill a specific goal of the designer.  Other attributes are unrelated, such as reliability and ease of looping up.

I tend to think of reliability in terms of design and durability in terms of materials.  Durability simply means resistance to rot, wear and breaking.  Slings that come to mind with durability issues are the leather 1907 and the cotton USGI web sling.  Leather and cotton are both subject to break down and rot much more readily than nylon or biothane.  I have had no personal problems with either sling in this respect, so taking care of the sling may delay such wear to a great degree.  Leather is very hard to cut, but it does have a propensity to stretch, which brings us to reliability.

For people who depend on their guns, reliability is usually at the top of the list of demands.  In a sling, reliability means that the sling will not fail to fulfill its role as long as it is not broken.  In carry mode if the sling fails, the rifle falls, possibly subjecting it to damage (or at least some doubt as to its zero).  In shooting mode, if the sling fails, the loop fails to take the place of the arm muscles in supporting the rifle and the benefits to precision are lost.  The only slings that have ever failed for me personally in either function have ironically been military slings.  The leather 1907 sling’s adjustment holes tend to elongate, which allows the ‘frog’ hooks to slip out rather easily.  The hook can slip out when the sling is not under tension, which makes for a surprise when tension is applied.  Competition shooters either buy new slings or sew the holes to re-tighten them.  On the USGI web sling, the adjuster that makes the sling so easy to adjust on the fly can come open if it’s worn or not closed tightly enough, which will give a similar unpleasant surprise.  Both have happened to me under normal, casual conditions.  The loop can be under significant tension during shooting, and many of us have heavy and expensive guns, so reliability is very important.

Loop stability is an interesting subject.  Fundamentally, loop stability is dependent on two things: the proper fit of the rifle to the shooter and sound technique.  There is a sweet spot for the placement of the front swivel.  If the stud is placed too closely to the shooter, his support arm will be choked up uncomfortably and the point of his elbow will be placed on the ground in the prone position.  If the forward stud is mounted too far forward, it will allow the support hand to be placed so that the upper part of the support arm flattens out.  This gives the sling loop less of an angle to grab onto the arm, which can make it susceptible to slippage.  Likewise, if the shooter places the loop too low on the support arm it will not have the full triceps to ‘grab’ and will be more likely to slip.

With a properly set up rifle, any quality sling will remain stable in its spot high on the support arm.  With a less optimal setup, some slings will slip more than others.  Constrictor slings tend to slip much less than static loops, the USGI web sling being top in this regard.  Static loops vary widely based on the webbing thickness, how slick the webbing is, and what type, if any, mechanisms are available to close the loop over the support arm (a disadvantage of the Ching sling).  Thinner webbing may bite more, but thicker webbing will spread out whatever friction the material has to offer, so it’s a balance based on the materials.  The degree of slipperiness of the material really depends on who makes it.  Leather can be really slick or it can grab well.  Cotton usually grabs well.  Nylon is typically slick, my RifleCraft slings are exceptions to this.  The nylon in my slings is more coarsely woven and tends to grab like cotton.

Comfort is not a difficult thing to get from a sling, but the designer has to have thought it through just a bit.  The key to a comfortable sling is keeping hardware away from contact with the shooter.  This is what was so disappointing to me about the TAB gear sling.  They put the loop adjustment right where the support hand is wrapped.  The support hand takes a good deal of the recoil force, which causes some pain.  When the shooter starts associating pain with the gun firing, bad things happen to his precision.  The mark of good gear is that it functions unremarkably without drawing the shooter’s attention.

Adjustability is tricky.  It’s hard to find a free lunch here.  I mentioned above that ease of adjustment is generally inversely related to reliability.  Of loop slings, the easiest loop to adjust is the USGI web sling due to its cam lock buckle.  This, along with its cheap price, makes this sling a nice choice for new shooters who are just learning to use a sling, and have low demands for rapidity of looping up or reliability.  The adjustment on the USGI web sling is infinite within its length, which means that if the shooter feels the need to have specific settings for different positions, they will need to be marked (not a big deal).  The 1907 is nearly as easy to adjust, but the adjustments are limited by holes every inch or so (not a big deal).  On both of these slings, as mentioned above, the adjustments compromise their reliability, the USGI adjuster being prone to spontaneous opening and the 1907 adjustment holes stretching and becoming unsecure.

I have come to favor slings with limited ease of adjustment (“set it and forget it”) simply because they make the sling simpler to use and more reliable.  I think the ability to reset the loop length for different positions is vastly overrated.

Rapidity of looping up is a large part of what makes a sling practical for field usage.  If someone thinks that the USGI web sling is viable as a loop sling in the field, they haven’t properly thought it through.  The rear of the sling needs to be removed from the stock.  The loop needs to be pulled from a metal slide, the sling turned, the arm shoved through, the loop pulled taut, yada, yada, yada.  With a lot of practice 20 seconds is probably attainable.  That’s just way too slow in the speed of real life.  Ironically, the 1907, which is the predecessor to the USGI web, can be gotten looped up in about 7 or 8 seconds if the configuration is modified a bit.  If you think about a deer standing still with a nice broadside presentation, 7 or 8 seconds will seem like an eternity.  Both the Ching sling and the RifleCraft RS-1 can be gotten looped up in about 3 or 4 seconds, which in the same situation doesn’t seem quite so egregious a length of time.  The RS-2 is just a second or two behind.

I consider any sling that needs to be reconfigured to go from carry mode to shooting mode and vice versa a deal breaker.  It’s completely unnecessary and impractical.  Any sling that has a propensity toward failure in design or materials is, likewise, off my list for consideration.  That should explain why I made my own sling.

So while there is little to distinguish the many loop slings in what they put on the target, there is quite a difference when it comes to the practicality of using the slings in the field.  While the USGI web sling is better than many for learning, the ease of adjustment becomes a disadvantage due to decreased reliability, and it simply takes too long to loop up with to be considered remotely practical.

How Does Sling Design Affect Precision On Target?

To those of us who are outside the competitive arena and using gear appropriate for the field?

Probably not at all.

There is a plethora of shooting slings on the market.  I often read about such and such being superior to other such and such sling when it comes to grouping downrange.  Precision is one area where sling design really doesn’t matter much for those of us who practice for use in the field and aren’t competing with specialized gear.  This assumes, of course, that the sling is a quality piece and set up correctly.

There are several varieties of loop slings that all function structurally in essentially the same manner.  I pointed out in my previous article that the loop sling is simply a taut connection that runs between the support arm just below the shoulder to the rifle just in front of the support hand.  This connection takes the place of the muscles within the span of the sling and allows them to relax.  Relaxation is much more better than tension if you want your bullet holes to be more closer together on the target.

The cotton or nylon USGI shooting slings, as well as the Tactical Intervention Slip Cuff are loop slings that constrict around the arm like a slipknot.  I call this variety of loop “constrictor style”.  This type of sling will constrict more tightly as it is pulled with greater force.

The other type of loop sling is simply a loop adjusted to a fixed length.  Instead of a slipknot, picture a simple closed loop that runs from the front sling swivel to the support arm.  Examples of this type include the 1907 sling, the Ching sling, the Tactical Intervention Quick Cuff, the TAB gear standard sling, and my RifleCraft slings.  I call this style of slings “static loop”.

The type of loop, constrictor or static, is irrelevant in determining whether the sling functions as a loop sling and puts the results downrange.  Sling design makes a difference in the technique of looping up and feel, but really only as a matter of preference, ease, and practicality of use.  That is to say that the process of setting the sling up to use may be vastly different between slings, but the final effect once in position is very similar.

Any of the following slings will positively affect precision similarly:

RifleCraft RS-2 Sling with simple, large, static loop.  My favorite all around sling.

I have shot with each of the above slings extensively, except for the Tactical Intervention, which I only used for about a month (it was borrowed).  I can tell you that they are all capable of steadying the shooter, each about the same as the next so long as the sling will stay put on the shooter’s arm.  There is no voodoo about any of them that will cause it to magically do something more that what it’s physically capable of doing (no, not even the ones that are ‘tactical’).

Likewise, whether or not a keeper is used to close the loop tightly over the arm (which is not possible with a Ching sling) is not a critical consideration in understanding how the sling functions.  Another way of putting it is that the size of the loop is not a factor in its fundamental function.  The wide open loop of the Ching does the same thing as the comparatively difficult to produce and extremely tight loop of the USGI web sling.  Sometimes a keeper is a necessary aid for a sling to work properly by staying put on the shooter’s arm, but that it platform and shooter dependent.

As an illustration of the above two paragraphs, a common misconception is that the Ching sling functions as a hybrid of a loop sling and a hasty sling.  It absolutely does not.  The Ching sling, as defined by function, is a loop sling, with all the attendant benefits of a full loop sling, and will produce downrange results similar to any other loop sling.  The technique of looping up in a Ching sling, or a RifleCraft RS1 sling for that matter, looks and feels similar to the technique of using a hasty sling (although actually faster and more simple).  This causes some to mistakenly conclude that the function is somehow less than that of other loop slings that requires a more difficult and elaborate technique to get into.

Don’t make the mistake of confusing effective results with difficulty of use.  A difficult and more elaborate ritual won’t necessarily make for more powerful magic.  The 20 seconds that it takes to convert the USGI web sling to a loop and to get the loop on does not make it more precise than a Ching or RS-1 that can do the same thing in 3 or 4 seconds.  Easy can be just as effective (or more) as difficult.

Without understanding what the sling does and doesn’t do, a shooter can’t use it to its fullest utility.  Misunderstanding the function of the sling can also give a shooter a belief in benefits that the sling cannot convey.  I hope after reading you have a fuller understanding of the sling and its function.

How Does The Shooting Sling Actually Work?

I’ve written a lot in the past about rifle slings and how to use them to steady a shooting position.  I’ve touched on why to use them and why not to use them if a supported position is available.  I’ve gone into considerable depth on how to use them.  One thing I haven’t really written about is why the shooting sling works.

I like to watch how people use their slings.  I frequently see people do things that are ineffective, or less effective than they could be.  My response to this has always been to beat the drum of better technique, but I think there is a more fundamental way to approach the problem.

Part of understanding how to use a tool is to comprehend how it functions.  It took a long time for me to even consider this with reference to the rifle sling.  I first thought of the sling as something to buy, as in which one do I want based on who uses it, how it looks, what it’s made out of, price, etc.  Then I thought of the sling as a process.  It’s a rather complicated thing for a new shooter, so I spent a long time processing how to use it, improving my technique, re-evaluating different types of slings based on what I’d learned in the process of becoming a skilled shooter and then an instructor.  When I felt my knowledge in sling shooting had matured, I designed my own sling, and I thought and worked a lot on how to make it better over time.

To really understand how to employ the sling and what it can and can’t do for you, the primary lesson to learn is visible in its structure and function.  Let’s take a look at the sling in use to better understand what exactly it is and what it does.

 

Structure:

 

IMG_7562
RifleCraft RS-2 sling, demo model.  I made it special with a foliage loop portion and coyote tan rear portion so it would be easier to point out exactly what I’m getting at.  This photo, and those that follow, depict the totality of the line of force of the loop sling.  From the forend, and wrapping the arm.  That’s it.

First of all, we need a precise definition of what it is we’re looking at.  I’m not an engineer, so I apologize it you are because I made up my own terminology and definitions.  A loop sling is simply a direct, closed, and isolated connection between the arm and the forend of the rifle.  Direct means that it goes straight in one line from the arm to the forend.  Wrapping the support hand in the sling won’t compromise this attribute, as the hand effectively becomes part of the front connection.  Closed means that the length of the connection is fixed and not subject to change without a deliberate user input.  Isolated means that there are no other related connections that impart forces in any other direction.  Although a connection to a different section of the sling that makes it usable as a carry strap can be, and usually is present at the rear of the loop, it should be slack when the loop is used.  Put another way, the loop is a simple, single line of tension from the arm just below the armpit and the rifle in front of the support hand.

The function of the loop is directly related to its structure.  What can a line of tension do?  Perhaps this is best revealed by examining what holds a rifle up in absence of the loop sling.  The greatest degree of oversimplification I can make is to say “bones and muscles” hold the rifle up.  Bones are structurally rigid and can’t be removed from the equation unless there is something to set the rifle on or suspend it from.  Obviously the loop sling is not capable of replacing the structure that bones provide.

It should be apparent at this point that the tension of the sling takes the place of the muscles between the origin and insertion of the loop.  When optimally configured with the support hand wrapped in the sling and front swivel used as a hand stop (as pictured), those muscles include the biceps and all the muscles that control the wrist, hands, and fingers.  Muscles, being subject to fatigue and errors of control and coordination, are major contributors to a shooter’s arc of movement.  Eliminating their necessity and use whenever possible is the mark of a skilled and efficient rifle shooter.

 

Limitations of the Sling:

Recognizing what the loop sling does not do is just as important as knowing what it does.  The simple loop sling has very little ability in assisting, supplementing, or replacing any muscle outside the length of its span.  The little ability is does have in this regard is due to the tension that is imparted toward the interface of the rifle butt in the shoulder.  This is why Jeff Cooper was correct in his adamancy that the benefits of the loop sling could only be fully realized with the support elbow planted, whether that be on the ground, a solid object, the knee, or somewhere else.  If the support elbow is not planted, many muscles are brought into play in order to keep the elbow raised and the posture of the body in the shooting position.  This does not negate the effects of the sling within the length of its span, but it does minimize the significance of those effects to a large degree.

Also, some of the potential benefits of the sling, particularly those involving the muscles governing the hand, are dependent on the use of a handstop when shooting with a loop sling.  Without some kind of handstop the support hand will need to grip the forend.  The location of the support hand will also be subject to potentially (very likely) greater variability.  Consistency is important, so the lack of handstop and the resulting variation in location, coupled with the need for muscular input will likely compromise precision.  Target shooters use purpose built handstops.  The rest of us use our front sling swivels, so the location of the front swivel is another important component of rifle fit

In the next installment I will examine the influence of individual sling designs on how the sling functions as a marksmanship aid to enhance precision.

 

Confidence, Part 3: On Demand

The time I spent focusing on shooting from a standing position recently was definitely time well spent.  I have to confess that there was a huge disparity in my level of confidence between dry fire and live fire that was present only in the standing position.  It would not be a great exaggeration to say that I felt like I could hit the head of a pin at 50 yards in dry fire, but I worried about missing a full sheet of paper at the same distance in live fire.  This feeling used to be a lot worse.

When I shot my standing groups in June of 2011 in preparation to launch this blog, I almost had a feeling of anxiety about the group I was shooting.  Dry fire had felt so stable, and live fire was feeling almost unimaginably unstable.  I didn’t generally think my ’06 had a lot of recoil, but I picked up a flinch in short order and it was enough to add to the nervousness.

I made a point recently to get to the range almost every week and shoot a few groups from standing.  The regularity of both dry fire and live fire was helpful.  It made the disparity in feeling between the dry fire and live fire stand out that much more.  What I started noticing was that I was not confident in my ability to make the shot on the 4” target from 50 yards, although in dry fire, I could usually break the shot with the sight very near a target the equivalent of about half that size.

I also noticed that the process of breaking a shot during dry fire was almost casual while in live fire I would hover over a sight picture afraid to disturb it by pressing the trigger.  Too long a hold puts a strain on one’s oxygen supply and everything starts to degrade, so generally things only get worse with hesitation.  Some of the problem was that I had to reinforce my follow through to a point where I could extend my fundamentals through the break.  Another part was a lack of awareness of my balance breaking down which I addressed last month.  Those were all contributing problems, but they were not the primary contributors.

To increase my confidence in live fire, I moved closer to the target, up to 35 yards.  All the shots were on target, but the group size was still mediocre.  As I moved back, the angular measurement of my group got smaller.  My confidence was improving, which allowed me to be more aggressive in my firing.

When I got back to 50 yards, I don’t know if it was a psychological hurdle, or that my ability to group was pushing the limits of my target size (probably both), but I had a setback in my angular group size for one group.  It was a good opportunity to observe the phenomenon of my performance choking a bit, and I quickly got back in form.

Why Did I Choke At the Range?  Aim small, miss small.

Here’s what I think was going on.  Calling shots in dry fire is a bit of an interpretive game.  Recently I would pick out a cluster of red berries on a tree outside and dry fire at them.  Many of the clusters were smaller than I’m capable of hitting on demand, but I was pretty happy if I could keep my shots within a certain radius, say a mil, from the center of the intended target (for reference a mil is 3.438 MOA, and the largest radius that will fit inside the 5 point scoring area on the standing portion of the AQT is 3.493 MOA).  However there are no stakes for “hitting or missing” because it’s dry fire.  Therefore I was accepting close misses in large proportions without worrying about it at all because the angular measurement of my total shots appeared to be consistent with a pretty good group size.

Another type of practice I did that had me frustratingly choking at the range was single hits on targets at both the 7 yard and 25 yard lines.  My practice in this venue was time driven.  To improve my times I would also accept a proportion of misses as part of getting faster.  This method of working speed is known as “zero or hero”, as opposed to a reliable “on demand” type practice that is more conservative.

I think that accepting misses in practice created a disparity between my attitude in dry fire and live fire.  In live fire I really don’t want to miss, and there is no credit given for misses, even if they would represent a decent group.  A 50% hit rate is garbage, in my opinion.  Thinking of it in that way made it clear to me that for the type of shooting performance I feel I need to be capable of, the zero or hero methodology is fatally flawed, and at maximum should be carefully employed in very limited doses.

Know Your Limits, Then Push Them

The old adage “aim small, miss small” is not applicable to people who don’t want to miss.  I think it’s actually a recipe for learning to miss.  Showing up to the range and wondering what’s going to happen may be exciting, but it does not foster confidence.  In my experience it caused me to be nervous when my performance was on the edge, even when the stakes were only photos of my groups in the internet.

A better approach is to be well aware of what you are actually capable of, then deliberately train to increase your capabilities incrementally.  It’s similar to using progressive resistance to get stronger.  It would be silly to go through the motion of deadlifting with no weights, then to head to the gym and attempt to do it for real with 500 pounds, just hoping for a good outcome.  A messed up back is something that gets one’s attention in a hurry, but for some reason a bad group is very easily written off as a fluke.

It’s important to be the type of shooter who hits the target.  Starting from a point where hitting the target is a given will train the mind to get hits as a matter of course.  Increasing the distance incrementally after hitting the target is well established will allow the shooter’s capabilities to grow.  He will also be able to discern what type of shots he can and cannot make, which will allow him to make informed decision on ethical shots in the field- with confidence.

 

Confidence, Part 2: The Other Half

Knowing the Objective

In the last article, I introduced the importance of confidence to the rifle shooter, which I defined as follows:

Confidence: A reasonable belief, based on prior measured performance, that there is a likelihood of successfully accomplishing a given task, where the performer has knowledge of the necessary requirements for that task.

I thought it was similar in principle to a quote by Sun Tzu that I have read many times:

“One who knows the enemy and knows himself will not be endangered in a hundred engagements.  One who does not know the enemy but knows himself will sometimes be victorious, sometimes meet with defeat.  One who knows neither the enemy nor himself will invariably be defeated in every engagement.”

In modern terms, and with respect to shooting, to “know oneself” is to have a handle on one’s measured performance (preferably with reference to a standard).  What does it mean to “know the enemy”?  The ‘enemy’ in this context is the objective, whether it actually is an enemy, or is a target dimension, distance, and environmental data, or perhaps a known course of fire.

Going into a task blind is like rolling the dice.  No matter how good a shooter is, without knowledge of the problem he is going to solve, he cannot have real confidence.  Feeling confident in such a situation is foolhardy, which I would define as overconfidence.  The only acceptable way to proceed in such a situation is to accept that you don’t know what the outcome will be and do your best, which I would define as uncertainty.

Example: The AQT

I started shooting the Appleseed AQT in 2009.  Of course I showed up with some pretty green rifle skills not knowing how I might do.  I was optimistic not only for a ‘rifleman’ score of 210, but secretly hoping that I might even score a perfect 250.  I ended up with I the high 220s or low 230s.  Between events over the next few years I would do something to get better, and show up hoping to shoot a 250.  It wasn’t until October 2014 that I figured out that I should do something about knowing my objective.

I realize that at any point I could have just pulled out an AQT target and shot it.  The idea of practicing on the AQT just doesn’t appeal to me for some reason.  I understand that specificity in training is theoretically ideal, but the AQT is more of a guilty pleasure, like pizza.  I don’t want it to color my training in such a specific way, and I need my primary diet to consist of meat.  I also think I can get the data I need in ways that will make it more generally applicable to my shooting.

Instead of using my past scores as a barometer of how well prepared I am (was) to shoot a 250, I did some figuring a while back.  I measured the largest radius that would fit inside the 5 ‘ring’ on each stage of the target.  I still think in terms of extreme spread, so I also converted the number to a diameter. The scoring areas are not circular, so I do still have some extra margin for error.  When I cannot be precise I like to be conservative, so I’ll have some extra wiggle room on “the day”.  I converted the measurements to minutes of angle at the correct distance, 25 meters (approximately 27.34 yards).  This allows me to shoot at any distance and relate it to this particular standard.  I even have a section on my spreadsheet that tells me at what distance my ‘standard’ target is equivalent to the size of the 5 ring and the ‘V’ ring for each stage.  This is especially nice because I can be working on pretty much anything and still relate it back to that specific goal.

Whereas I used to ‘hope’ that I might show up and shoot a 250, when I am able to keep my shots within a certain radius with an acceptable amount of deviation (point of aim to point of impact) in each shooting position and time limitation, I will have confidence that I will shoot a 250.  I realize it’s not a guarantee, but it’s a reasonable belief based on prior measured performance, where I have good knowledge of the task at hand.

 

Confidence, Part 1: Understanding

 

Confidence: A reasonable belief, based on prior measured performance, that there is a likelihood of successfully accomplishing a given task, where the performer has knowledge of the necessary requirements for that task.

Overconfidence- an unreasonable or misplaced belief in one’s abilities without a thorough evaluation of one’s skill and/or knowledge of the requirements of the task at hand.

Uncertainty- doubt in one’s ability to perform based on inexperience, lack of knowledge of one’s own abilities, or of the challenge difficulty.

Confidence is an indispensable tool for a rifle shooter.  There are many technical processes involved in firing that need to flow along unimpeded for the shot to be released correctly.  If doubt creeps in the chain of those processes gets disrupted, causing the level of one’s abilities to be upset.  Lack of confidence can therefore cause the shooter to miss a shot he would otherwise be capable of.

On the other hand, overconfidence can cause a shooter to make decisions that can lead to a miss.  Mistaking internet lore as normal reality, conflating 3 round groups or bench groups with realistic hit probabilities in the field, or even thinking that the extreme spread of a 10 round group is indicative of the extremes of one’s limits are just a few ways to fall into the trap of overconfidence.  Having a belief in abilities that one does not possess (credit to Derrick Bartlett for that line) is a sad way to exist.

In my own shooting, up until last year perhaps, I experienced a cycle of overconfidence followed by uncertainty.  Those conditions are both associated with a lack of information.  I do not believe I was alone in this respect, and believe that most rifle shooters are in this cycle as well.  I confused what I wanted to be able to do with what I should  be able to do.  I repeatedly set myself up for failure by expecting a mythical standard, and repeatedly being confronted with what I actually was able to do.  I can tell you that the drive home from the range is a downer when the expectations were set too high on the way into the shooting.

How does one cultivate real confidence to take on a given task?  A quote from Sun Tzu came to mind:

“One who knows the enemy and knows himself will not be endangered in a hundred engagements.  One who does not know the enemy but knows himself will sometimes be victorious, sometimes meet with defeat.  One who knows neither the enemy nor himself will invariably be defeated in every engagement.”

The first piece of the puzzle is to know what you are capable of as a shooter.  What you think or hope you can do is not valid data.  A paper target will not lie, but I’ve sure seen that it’s not uncommon for people to interpret what the target tells them in creative ways.  The ego can lead a person to near blindness in order to protect itself.  It’s necessary to fire enough shots to have a valid sample with which other shots taken in similar conditions can be predicted, and then to accept each shot regardless of how badly you wished you hadn’t fired it.

Measuring performance can be difficult, but it’s a step that can’t be skipped.  To make it easier to figure out where to begin, some of the primary variables to take into consideration are time, terrain, and the target.  They are all related, and all will be components of how difficult and demanding the shot will be in the field.

Terrain presents an overall context to the shot and will likely be a decisive factor in determining the shooting position.  That indicates a need to test enough positions to cover the possibilities of height requirements, with and without support.  The amount of time available to fire a shot is inversely proportional with the difficulty of that shot, everything else being equal, so it’s necessary to know what happens to your performance in a time crunch.  The target generally chooses the terrain, sets the time limitations, and its own size finishes off the formula of shot difficulty.  Actually an additional factor is what the target is doing in terms of movement, but to make the matter of measurement one that can be practically carried out we can put it off until later.  For one method of combining these measures, see my October 2014 archives, in which the entire month was a presentation of my position analyses.

Until you are able to accurately and precisely measure your performance you will not, as Sun Tzu says, “know yourself”, and if he is correct, you’ll be subject to defeat in every engagement.  Shooting in a consistent way and measuring it is work. There is no way around that, but work is required to get most worthwhile things done.
