I only messed with muzzle loaders a few years in my teens and twenty's. I picked up a four cavity ingot mold somewhere and used to cast all the wheel weights from our friends Amoco station. It was a Lyman mold with their logo in it. Your ingots are probably store bought, but mine were not. Don't worry Gary, they all went to the scrap yard. Guess it really doesn't matter, Gary uses wheel weights too. Just get his recipe.
