Home Forums Reloading Bullet Casting Heat treating and cold hardening plated bullet?

It will only work if you can find plated bullets with a significant antimony content, at least 2% but preferably more. A little arsenic in the alloy is supposed to be helpful too. Most of these are made with near pure lead to make the swaging process easier; pure lead will not quench harden.

Your idea has some merit, but I don't know if anyone makes plated bullets that have enough antimony in the alloy. I've thought about asking our local bullet maker to make some in a harder alloy like that for the same reasons; their bullets are soft and don't shoot as well in my guns.
