Yes, you both have a point about the wind. It was gusting and blowing a fair amount.
I guess when I say 'open up', I meant more that just geometrically. Since I get 1.25" groups at 100yards, I should be able to get 2.5" groups at 200. But, of course, the winds must be calm. I guess I should expect the groups to 'open up' and exceed 2.5" when the wind starts blowing.
I can't wait to try the Black Hills variants.
