My favorite is when I forget to dial back after a long shot. Nothing quite as cool as shooting 4 feet over a prairie dog at 100 yards.
I am not bad about doing that when I am hunting.....but I have forgotten twice while dialing scopes for the wife, causing her to miss a couple animals by about 15 MOA. I bought her a scope with a zero stop and taught her to dial. It is safer that way. I think if I had done that to her again I would have gotten shot.
