Long Range Transitions
This test isn’t what most people would consider to be “long range shooting”, but in the context of the target I’m using with the 4.2” primary scoring ring, at 330 yards, which is the longest distance in this test, the target is about 1.2 MOA. That’s not overly large (or large at all). That’s actually small enough to be somewhat difficult with a rifle that in the last test looked to be just under a 2 MOA gun on average.
This tests consists of 36 rounds fired as single shots on 4 different targets. That would give me a 9 round group on each target to evaluate if no mistakes were made. To avoid getting into the comfort of a patterned sequence for transitioning from target to target, I came up with a shooting order that balanced the permutations of possible transitions as best as I could. To avoid any learning that would invalidate the results of future tests I will mix up the order of presented targets left to right while retaining the firing order left to right as each new optic is tested.
The target distances are 170, 230, 270, and 330. That makes for an average distance of 250 yards. 330 is a little far for this system’s capabilities on a 4.2” target, but I wanted to get out a little bit so a larger elevation correction was necessary.
The purpose of this drill is to test the usability of the reticle for holdovers and to test the ability of the scope to get me on target. Those sound like the same thing, but with the latter I’m talking about my ability to actually see what I’m shooting at and how that might translate into better speed, precision or accuracy.
Before shooting this test I already have the holdovers written down, the rifle loaded, as spare mag ready within easy reach, the scope set at maximum magnification (no lens covers on), and myself in shooting position. This is not a gun handling test, a math test, or a test of interacting with other equipment. The idea is simply to be given a specific target, apply the necessary hold to hit it, press the trigger, rinse and repeat.
The target sequence is typed in two columns on a single sheet of paper. The holdovers are also written down nearby. For each shot I need to check the sheet, verify the hold, fire, pick up the pen and check off the shot in the sequence.
I kept track of my time as best as I could. In this case I used a stopwatch. It’s not as good as a timer but at least I can still get an average split time. The battery on the iPhone happened to die right before the test this time, so no “timer” (app).
Some other things went wrong. I was using a tarp as a mat in the barn lot. The tarp bunched up a few times and got in the way. It probably cost me a good 10-15 seconds. I also experienced some confusion on the order of targets, and put an extra bullet into the 330 yard target and one less bullet into the 270 yard target. Oh well. I still have relevant stats in reference to points per shot, mean radius, and time per shot.
There were no real difficulties with the scope. It was pretty straightforward as far as the shooting went.
The entire sequence took 390 seconds. The average time per shot was 10.83 seconds. Remember that picking up a pen and writing was involved, not to mention verifying a hold and whatnot.

Accuracy/Group center vs. point of aim:
Range Vert. Deviation Hor. Deviation Tot.Dev.
170 0.014 0.017 0.022
230 0.25 0.04 0.25
270 0.21 0.63 0.66
330 0.25 0.30 0.42
That’s about it. I promise it will be more exciting when there’s something to compare it to. That will be fairly soon.
