I cast for both muzzleloader and black powder cartridge guns, so I am able to use soft lead, WWs, and range scrap. I got a box of range scrap off the CastBoolits forum a while ago but haven't used any yet. I normally use the WWs mixed 50-50 with soft lead. That is supposed to make alloy that is close to the Lyman #2 alloy. When I use the range scrap, I will probably mix that with soft lead too. Depending on the gun, I will just cast straight WWs. Yeah, keeping them all straight and ID'd is s challenge sometimes.
