have your buddy hold the target above his head while running..... just kidding!!!!! There was a range I used to goto that had moving targets at 50, 75, and 100yds. It changed my way of thinking when I could shoot .5" groups from a bench and when trying to hit a 10" steel plate moving at 5mph or so wasn't as easy as it looked at first.
I read an article years ago about getting a hunting license in Norway you had to hit targets at various distances, moving and stationary. You had to be able to put all your shots in the animals kill zone otherwise you were not able to recieve your tag. That sure would cut down on alot of wounded animals that's for sure.
