great idea kraigwy. I have access to the indoor range and regularly get my 9mm cases from there, but never thought of getting lead there too. I could easily volunteer for inside cleanup as part of my yearly labor dues. Great idea.
I get most of my lead for "free" by cleaning the bullet trap once a year at my indoor range. It's hard and nasty work; you earn the lead, they're not just giving it to you. Wear a good mask (N95 or better), and maybe even goggles, so you don't poison yourself from all the dust.
Bullet trap lead is good stuff. I have no idea what the alloy is, but it has enough tin in it that it doesn't tarnish, and enough antimony that it hardens pretty good. Not as hard as clip-on wheel weights or shotgun shot, but hard enough.
