Wheel weights are ok for some loadingapplications, but I mainly cast
projectiles for my blackpowder rifles. I've read that wheel weights
contain tin, and the tin will cut upthe riflingin yourriflebarrel eventually.

No, I don't order it. What I have on hand now came from a factory that
that used it as heat shield panelson their molds. Roofing lead and
plumber's lead are a few good sources. If you candent it with a finger
nail, it's good lead.
