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 .
