I didn't worry about shooting 4" groups today.  I thought more about having as many "good" shots as possible out of 60.  I usually get a little eye weary after 40, but today I was fine.  Maybe the rest day on July 4 helped in the heat this morning.  I was still tired after an early morning dog walk and then a bunch of trips to the 100 yard target backer.  My fan-cooled video cameras worked perfectly and I set everything up right so this is a (technically) good video. 



The IMI ammo shoots perfectly in this 4" barrel (this lightly used estate sale Primary Machine match barrel from Wobbly is fantastic), as it does in the P-10F.  I'm saving my Atlanta Arms ammo for the P-10S. 

One "flyer" (the low shot on target 1) out of 60 rounds is a good day at 100 yards, especially compared to last week.  Today, getting 57 out of 60 shots on the 10-1/2" square B-6C repair centers with two a little high due to zero adjustment is a good result.  I MIGHT be able to improve a little next week, we'll see.

This is fun.  This isn't easy.

I published the video above without much analysis.  "On further review"  I've found that there were actually three good sub 5" sequential five-seven shot groups on those targets, one on each target.  So I edited out the other shots and added the red bullet hole markers and some notes and here is the roughly one minute video...



This reminded me to mention the one gripe I have about the pistol reflex red dots in general--the zero adjustment clicks are typically rated for 1 or 2 moa per click, but I ALWAYS experience much larger shifts in POI than that at 100 and 200 yards.  Doesn't matter if it is a Holosun or Burris sight, the adjustments are too course for me at 100 yards.  There are two adjustment choices for each screw--too high or too low, a little left or a little right.  Some times I can adjust the hold a little, which is what I did on the last target "see a little black at the top of the dot" and that lowered the average shot placement "about 1/2 a click".   But when the greatest challenge is eyesight anyway, trying to hold 3 or 4 inches shift in any direction is pretty darn difficult.

It is much easier at 200 yards to get the groups centered.  Just move the aim point, since it is already on a stick 3-4 feet above the target anyway.  That is what I used to do at 100.  I left the pistols zeroed at 25 yards and put the aim point just above the target, and then moved it to center up the groups.  But at my local range, the backers are at grade level and I damaged too many backer frames making the adjustments, so I went to a 100 yard zero to get a little more backer surface area to work within. 

But, to summarize, the Friday results with the P-10C were really good, at least for me.  I am really looking forward to a few more "good" 100 yard sessions here locally before moving out to 200 yards soon.
