Right about at 30 yards for a deer standing still and calm. And for a spooky deer, 15-20 yards at most. Like someone had said, shooting at targets is completely different than shooting at live animals and too many variables come into play. Can you also shoot two inch groups at 40 with ALL your hunting clothes on..gloves and head net included, standing in a tree stand 10-20 feet up, most likely shooting at a moving target? That wasn't a shot at you. Just something to think about.
