Scalf - my groups are much tighter at 50 yds; I never bothered to measure because this is what you expect for this rifle. I'd expect you get pretty decent groups at 75 yds as well?
Our range is limited to 100 yds, but you have access to longer distances. It would be great to see what you can do at 150, 200, or even 300. You would probably need adjustable rings like FX no limit, or Sports Match, because at these longer distances you are going to run out of hold over aim points on most scopes.
