I only shot this handgun about 50 times last fall when I got it just before hunting season. Today I went out to the range that I just joined. Nice setup, not very busy during the day time on weekdays. Can shoot out as far as 600 yards from bench or prone.
Anyway, I had never shot it off a bench before, always prone. I had the scope off to install Shawn's bolt release last month. So I shot (from the bench with bipod) one group each at 200, 400 and 600 yards to re-establish my drop chart. Two were 3 shot groups and one was 5 shots. All were just under or just barely over 1/2 MOA. I am still using the first load I started with. Never adjusted the OAL or the powder weight. I don't think I will bother.
Now my plan is to shoot often this summer from hunting positions, always prone or seated with bipod. Not a lot of shots each time out there. Just enough to keep up my muscle memory.
Could you mention again what your load is?
If not willing to post it, just email me please.
