I've been teaching my boys (9 and 11) to shoot with a Daisy 853.  We've been having a great time.  It's time to add a pistol to the fun, so I bought the Umarex Glock 19 BB gun.  Seems like a solid option for realism, cost, accuracy, and economical shooting.  

I'd eventually like to set up steel challenge-like stages in the backyard.  Would steel targets angled downward be safe to shoot (worried about ricochet)?  I don't want to piss off neighbors or break any windows.   Any better options (hanging soda cans)?

Don’t they make lead BBs?
