I have a pretty good sized stash of "purish" lead, but noit sure it's really pure enough for muzzle loader bullets (big solder donuts from cast iron water pipe, lead pipe with soldered ends that are probably some tin, etc), I also have a coffee can full of spent lead free air rifle pellets which I have verified through testing to be pure tin for all intents and purposes.
Was kind of figuring on melting down all the "purish" stuff into clean ingots and then using a scale to ensure real consistency from pot to pot, casting in mass with the Lee .45 colt bullet in six cavity and not having to worry about casting for .45 Colt for a very long time.
I also want to cast up a bunch for my .458 and .45-70s. I have always stuck to Trapdoor level pressures with both, so guessing this 20 to 1 will work for this.
Is this a hard enough alloy for plain based bullets in these two? I might cast a bunch of .38 DEWCs with it too.
