Muzzleloader and cap-and-ball shooters who cast their own round balls reach for the Lee .500-inch Round Ball Mould (Lee part no. 90452) for this bore diameter. Like the rest of the Lee mould line, it is machined from aluminum rather than heavier iron or steel, which means faster heat-up, faster cool-down, and less fatigue during a long casting run. The double-cavity block halves are CNC-machined for round, consistent balls, and the mould ships complete with handles ready to use.
