Seeing as how most guns will shoot better than most people can shoot them i would say 1 moa at 100 yds. There are a lot of people that go hunting in every state each year that can not shoot 1 moa at 100 yds off a sandbag much less off hand shooting at deer or any other game. I have seen people at the range zeroing their scope and if they can hit anywhere in a 6 inch circle at 100 yds they are ready to go hunting.
