During today’s shooting I wanted to try a couple odd things to see what, if any, effect they had on my downrange precision. The testing protocols were the same as my control group, same target, same distance, same time interval between rounds, same loading protocol, same scope magnification, and the same 3 round warm up group, which actually turned out to be a decent group:
0.74”. This is the type of group that a normal person might post on the internet… that one in a hundred that actually looks alright. An easier way to do it would be to crop out all the fliers.
I was expecting that third round to go farther astray, but it only went a little south.
The next group was left handed. A few years ago I had some strange experiences in which I was shooting some half minute groups left handed and not so well on the right. One thing I do have problems with is that the reticle is not focused and I see 2 vertical stadia lines sometimes, which may explain this:
1.31”. The vertical spread is about 0.75”
As a quick aside, and a short detour in the continuation of the lesson in posting good internet groups, take the above group. I cropped it and resized it again. Note that it was a 5 round group, but cropping out the left rounds yields this:
Further cropping will increase the impressiveness:
You’ll outdo all the other internet posters by saying that you shot 5 rounds at the target. This would be more effective by homing in on a stray flier of a 10 round group. You might need more resolution for that. My camera has 18 megapixels. Back to our scheduled programming…
The last thing I wanted to try for the day was to get up from the rifle and rebuild my position every time after firing a shot. I dry fired a few times to get my routine down, so that my feet were in the same spot every time, and I could basically fall forward into the waiting and loaded rifle within the 30 seconds between each round that I needed. I thought that this would ensure that my position was not being altered by the recoil.
1.79”. I’m not proud of it.
I’m still working my way down the list. For a refresher on the results so far, here you go:
Control group: 1.41”
Assisted trigger: 1.67”
Bag instead of bipod: 1.24”
Sling support: 2.97” (I’m throwing this out as a
Alternate sling support: 1.34”
Left handed: 1.31”
One thing I’m noticing is that each of the 2nd tests of the day are worse than the first. During the next trip I will repeat one of them to see if it dramatically affects the results.
