Extremely hard, lead ball media for ball milling black powder and individual chemicals.
If you are making black powder, you have to use non-sparking grinding media. Lead is non-sparking and is probably the safest thing to use for making BP.
Pure lead balls are very soft and will literally grind themselves down to nothing. Our balls are an alloy of several metals and lead which makes them harder than virtually any other lead milling media on the market.
A 5-pound (200 ea.) box of these balls is exactly the quantity needed for our 6-Pound Ball Mill (#TL5005).
