Guess I'm cheap. I usually grab a dozen or so of the spent shotgun shells laying around at the firing line and stand them up 5/7/10 paces downrange then dance them out as far as I can hit them. Man them things can dance! Lately I've been saving gallon milk jugs and plastic coke bottles to fill with water and shoot at as well. 'Course I'm only shooting handguns, 9MM, 40S&W and 45ACP. I know it's not really related but has anyone ever seen these?
