I've got some "experienced" shot that I'd like to use, not for reloading but for casting bullets. I'd guess they contain lead and antimony, but no tin, so tin (preferably cheap tin) is what I'm after for a 9:1 alloy.
Bar solder isn't cheap, nor is any solder I've looked at locally, and I've looked for tin flashing but so far, no luck!
So I was wondering what my other options are? Metal scrappers in my town only buy and then ship it all off to the PRC
