I think the thread is about shooting Groups??? We all know the hunting situation is not the same! I think the what if's should be in a different thread! A challenge is good, I shoot everyday from an elevated position, because thats the way I hunt. I personally don't shoot at moving targets because I won't shoot at a moving animal while hunting. I know my limitations! But I would mind trying to shoot at a tire rolling down a hill it just for fun!JMO!
