I'm sorta like you Lloyd, hitting beer cans every shot at a 100 yds, is hard to do, red dot sight or not. In my experience, when really pressed, most people can't do this on demand. A lot of people claim to be great shots, but when you try and get them to the range to prove it, they always have something to do. It's like my favorite deer rifle (7mm/08 Mtn. rifle), I have shot 1/2" groups with it before. Will it shoot 1/2" groups every time I carry it to the range, no. I would have to see a man shoot beer cans @ 100 yds. consistantly, with a Hi-Point, to believe it, or any other semi-auto for that matter. The key word here is CONSISTANTLY.
