Every year now since the early 90's a friend of mine hosts a gun-shoot, a few weeks before White-tail rifle season. The rules are use the gun you hunt with, some guys have open sights, most have scopes. Usually 15-20 guys show up. We stand free hand and take a shot at a standing cardboard deer at 250 yards, as soon as you shoot, a running deer cut-out moves threw the brush at 100 yards there are 2 clear openings. You get 2 shots at the running deer, but when it hits the end of the string your done, wether you got your last shot off or not. You'd be surprised at the bad shots and even "buck fever", on occasion, as the shooter gets harassed a little, from the crowd. The winner has to buy pizza, with some of his prize money. It's real good practice for deer hunting, my boy hit the running deer in the rump, so he realizes the dangers/problems of shooting at running deer. I tied for 1st this year but lost in the shoot off tie breaker, it's good times!
