I cast .25 acp up to .45, and some rifle bullets, all Lee molds and
big 20 lb dipper pot, I cast at shop door with fan blowing stink away from me, use a particle mask too, after casting a few hours
you can FEEL the dust on your face and hair, also I wear welding gloves, take a shower after and wash clothes, I think there is
alot of other bad heavy metals in those wheel weights, also I've
found rolls of lead that fume with smoke, I take a 15 minute break to let smoke clear,eye protection isn't a bad idea either,
be carefull and have fun.
