The holdover at 100 yards for a 9mm pistol is different at 6000 feet above sea level than it is at 800 feet above sea level. But I had the range all to myself, and the wind wasn't too bad, so I got to take my time and work the groups to the center of a B-8C target with just a 3 moa correction on the sight. Here is a video of the best target, two 5 shot groups.
https://youtu.be/fmoktulnkrYI usually don't make any zero changes but the P-10F was zeroed at 25 yards in the Hill Country and I had to go down 3 clicks just to keep the aim point separated from the target. Pretty sure I got it right without taking the time to zero the gun at the high altitude range.
I was able to shoot many good groups today with pretty much all of the rounds on the B-8c target, just not necessarily centered while I was fiddling with the elevation and the wind. I would have struggled at 200 with the variable wind today.
I've shot the CZ pistols at 100 yards so often now that I think putting 10 rounds out of 10 in the black at 100 yards is a reasonable goal, not an outlandish one.
Not sure what I will try tomorrow. Maybe 200 or maybe the rifle at 500 m. Depends on the wind. I need a dead calm day to shoot 200 with the 9mm pistols.
