I went to the range just before hunting season several years ago and watched a guy with a 300 weatherby trying to check the zero of his rifle. He was proud of the manly caliber, but terrified of the rifle. It was painful to watch him flinch so badly he couldn't hit the 4'X4' cardboard backing off the bench at 100 yards. Eventually I told him I had never shot such a powerful rifle and asked if I could give it a try. Someone had sighted it in properly, bang on 2.5" high at 100. This convinced him he didn't need to shoot anymore since he knew it was sighted in. He said he shot fine on game. I genty tried to tell him that a 308 was all he needed and the game deserved a well placed shot. It sorta worked, I heard he traded it off on a 444 marlin that he also couldn't shoot. The only consolation is he was so bad I doubt he could even wound an animal.
Another time at the range we had a turkey shoot, hit the 200 yard gong off hand and win a turkey. Business was brisk for a couple of hours. The end result was 3 winners. I'm not a crack shot, but sometimes I think the European countries that have hunters pass a shooting test before being able to get a licence have it right.
