Continued Experimentation

The next phase of experimentation to see if I can figure out my accuracy issue involved eliminating the bipod as a means of support.  Before testing that I shot 3 rounds as before to warm the barrel.

1
1.37”.  The first 2 rounds went into the bull.  I started thinking I had inadvertently cracked the secret code.  Shot 3 kept me from getting too big a head.

Next followed the experimental group titled “bag instead of bipod”.  I still used a rear bag as support.  The front bag support did not appear as steady as a bipod.  I had to work to keep the crosshairs centered on the bull.  This is what happens when you forget to bring stuff to the range.  It was better than the time I forgot to bring any ammo at all and had to drive all the way home and back.

2- 1point24 inches
1.24”

This is the best group so far, 0.17” smaller than the control group.  Not significant, especially for the sample size (what are ya gonna do?  Ammo is scarce.)  I’m tempted to try a steadier non-bipod rest and repeat.

I scheduled 2 experimental groups for the day, for a total of 13 rounds.  The second group, continuing with the non-bipod shooting, was prone with the sling.  I wasn’t feeling it, but shot the group.  I had made a minor sling adjustment and it was too tight.  The group was poor.

3-
2.97”

One week earlier, I had shot another 5 round prone group at the same range at precisely the same distance.  That group did not follow the exact testing protocol, and was done under time stress.  I did not have the luxury of worrying about the niceties of my position and did not notice any discomfort.

1.34”.  Better than I had thought just by looking at it.  0.07” better than the control group, although I probably shouldn’t count it.

  1. Hello Slinger,
    I am reading Rifle Accuracy Facts by Harold R. Vaughn. One of the areas he explores that affects accuracy is the method of screwing the barrel into the receiver. He suggests that this can result in the occasional “flyer”. Without going into detail are you sure your barrel is screwed on tight.

    On a side note Colorado Pete’s book arrived today courtesy of Amazon. I will add it to the pile of books I am reading by Aagard, Ruark, Wieland and Boddington. All big game related stuff at the moment.

    Now all I have to do is grow a handlebar moustache.

    Regards

    • ” Without going into detail are you sure your barrel is screwed on tight?”

      Is that a euphemism for the state of my mental health?

      I’m not sure how tight it’s screwed on. I don’t think there’s anything I can do about the current barrel because the extractor cut has to index on the extractor. I read that book too. I wasn’t quite sure what to make of it, but it really put a lot of doubt about the simplicity of getting a rifle to just shoot well.

      I’m going to shoot a few competitions in May, then I will see what I think I need to do as far as replacing the stock and the barrel.

      If you grow that handlebar mustache you’ll have to write your own book.

    • Scott, two things:

      First, I’d consider it a favor if you posted a review of my book on Amazon, warts & all (warts to be corrected in any second edition).

      Second, add Peter Capstick, Jack O’Connor, and Jeff Cooper to your reading list (if you haven’t already).

  2. Slinger,

    Of all of the people that have an internet persona you appear to have your barrel screwed on tight. So much so that I would venture the suggestion that you re-name your blog from the Art of the Rifle to The Way of the Rifle as you appear to be quite holistic in your approach.

    Good luck with your up-coming competition. May I suggest less concern about the result and continued diligent application. I believe that it is what you are trying to be rather that what you are trying to print on paper that matters the most.

    Thanks for “getting” the handlebar moustache reference.

    Regards.
