.......Perhaps I've been misinformed over the years...and someone please correct me if I'm wrong. I have always understood that MOA was approximately 1" @ 100 yds. It has been my interpretation that to shoot 1" groups at 300 yds., you'd best be shooting .33" or better at 100 yds. That is what I understand MOA to be for 300 yds.....sub 1".......???? And that is what I believed the post to read...."sub-MOA @ 300 yds."
