To load the mill jar optimally, fill it half full of a dense media such as 1/2-inch lead balls. 50-caliber muzzle loading bullets will work, but they are soft and will both wear down over time and leave lead dust in whatever it is you are milling. It''s better to antimony-hardened 1/2-inch diameter lead balls, made specifically for pyrotechnic ball milling. They cost a little more than the soft
