A buddy gave me some lead. He yard sale found it and gave it to me. It penciled out at 16-18 bhn and I thought it could make nice rifle bullets. I melt it in the pot and a lot of stuff came to the top. fluxed and its not mixing in. Tried casting a mold for 6.8 and 30 seconds later the sprue slid easily and the bullets were still molten looking. Dumped it all out and wiped the mold down. The bullets bent. The sprue lead broke and looked a cake like texture. Said Welp, not using this to make bullets.
Any ideas what it is contaminated with and what is could be useful for? Spinner bodies for fishing lures? Its about the same weight as lead, but not the same at all. Something at a lower melting temperature or is slower to setup than lead or WW lead.
