Thread: Bullet casting - is it worth it

Put on a surgical mask so you don't touch your face. Most lead ingestion is from ingestion of smudges off your fingers, not fumes, but do ventilate the room too.

On that note, bear in mind, carefully, that the black soot from a fired primer, which is also in the case and barrel is fine lead dust from the detonation of lead styphnate primer compound. If you never bothered about this, ask yourself why worry about lead exposure from casting? It's often the devil you can't see that's the most dangerous one, not the obvious molten lead in the pot and die right before your eyes.
@shooternz does a lot of lead casting, me may add some experience about lead exposure.

By the way, no, I'd not bother casting 9mm projectiles, factory ones are cheap as muck from e.g. Gunworks. Projectiles fully encased in pure copper to prevent any exposure of the reloader to lead (well, if you also use lead-free primers).
