I'm not new to reloading, but fairly new to casting. I read that even trace amounts of zing will ruin cast bullets. Why? What does it do to the alloy? With some wheelweights having zinc as a coating, it's cut down on my supply, although I figure I can probably seperate the lead from the zinc with careful application of heat from a torch.

Thanks for the replies guys. Lloyd, you told me what I really wanted to hear. I've got a bunch of wheelweight with some zinc that I want to use. Now, I'll go ahead and use it.
