It was suggested on a bullet casting forum that I try putting a squirt of dry graphite in with my round balls and allow them to tumble in a rock tumbler for a few hours. I opted to let these go overnight. During the casting process, some of my bullets ended up less than perfect, with small divots, casting and sprue marks left by the Lyman mold. This method resulted in balls that were perfectly round, with a shiny, hammered finish appearance. Give it a try— I think you’ll be most pleased with the results!
