Wait a minute.....I don't, my buddy does. I have been around commerial lead bullet making operations, they are hot and nasty. The home bullet DYI'ers is not nearly as bad. Whenusing lead wheel weights, you need to watch the tin and aluminum. The aluminum won't melt, but Tin will contaminate your whole run. If you are considering casting your own bullets, pick up the Lyman book on cast bullets. Great info in there. I rarely shoot lead anymore. When I do, there is a source here in town that sells them for $1 or $2 per pound bulk. At that price, why cast my own?
