Anybody know what they're made of ? I need to cast some balls for a
ball mill , and have a choice of pure lead or tire weight material .
I see sellers on ebay that have 10% antimony/90 lead for this use ,
others have pure lead . Still others have ceramic balls , but I'm
not sure those have enough weight for a small ball mill . The one
thing all have in common is that they're around a half inch diameter
. I figger the .490 ball mold for my muzzleloader will work just
fine .

Wheel weights are about..not exactly..but close to "#2 Alloy" They
are pretty hard for muzzle loaders, but they will...will work. They
may tend to cast a smidge small, sometimes...but the patch will make
up the difference.

A pure lead .50 ball will weigh about 177 grs (.490) while a wheel
weight ball may be around 165-170.

Not a hell of a lot of difference. Just dont mix and match..keep your
ww balls seperate from your pure lead balls.

Patching and lube differences are the bigger challenges when shooting
wheelweight balls

The wheel weights were intended for the .30 cal modern rifles . I have
enough pure lead for quite a few balls for the BP guns .
But this next run will be for a ball mill .
