I know this subject has been debated on end, but I have to ask because I want to actually know if someone has done it and what their results are. I want to know if you can cast round balls for a muzzleloader from wheel weights. I know what you're supposed to use, soft lead, but lead in some places, where I am, is getting tougher to come by. Even the wheel weights themselves is getting tougher, plumbers lead, everything is harder to come by and the more we see the "green" campaigns keep trudging onward, I think we're going to see less lead to use. I do have some soft lead on hand for round balls but I want to know if need be, can wheel weights be used. These would be for new production guns, nothing antique. Also, in my Pedersoli Indian Trade gun and French Cavallerie carbine, these are smooth bore guns that I use balls undercast anyway. For instance, my French gun is .69 that shoots very well and surprisingly accurate with a patched .648 and .662 roundball. My Indian Trade Gun is a .61 caliber roughly that does very well with a .570 roundball and .015" patch. So for at least those two guns, there isn't a super tight fit to worry about.
So, can it be done?
