Anyone interested in cast bullets owes it to themselves to join the Cast Boolits forum. I think you'll find that the vast majority of the members there are using wheel weights to cast bullets, with perfect satisfaction.

You have to realize that **anything** lighter than lead - zinc, steel, dirt, etc., floats to the top when the wheel weights are smelted. Once the dirt and scrap are skimmed off, there's no way for dirt and such to get into your barrel to cause any damage. In fact, the only problem associated with wheel weights that I'm aware of is that **lead** wheel weights are an endangered species!

Granted, the composition of the lead alloy from wheel weights can vary from lot to lot, so the thing to do is to smelt the largest amounts possible at a given time. A bit of tin (1-2%) added will greatly enhance the mold-filling qualities, and antimony can be added to increase hardness when necessary.
