I have a whole bunch of wheel weights that I want to turn into lead ingots for future reloading. Given that I dont have any equipment yet, what should I purchase just to do the ingots? Do you do this kind of work with the same furnace you use to cast bullets or do you use a more primitive method (i.e. cast iron pot on a propane stove, etc.) Please let me know what I should buy to do this first step.
