My daughter is lobbying for environmentalism here at our house, and I would like to accommodate her. The current topic is "how to set up a shooting range" on our farm. We shoot 22LR, 9mm, and 38/357.
We have a convenient hillside which would stop a bullet unless the gun was elevated greatly, and if a round were to skim over the lip (NOT the plan), there are only woods for several miles in that direction. I have parts and a design for a brass-catcher already. But she's concerned about lead in the soil.
I've seen the commercial backstops (a million little pieces of old tires in a box, if I remember), but we're operating in the tens of dollars range. I'm thinking of making a wooden box (2x10s?) and pouring a bunch of sand into it. Years from now, I can sift the sand to get the lead for someone who casts their own bullets.
Suggestions? Links? ...thanks!
