Re: Concern for lead exposure
Speaking as a Doc with a background in toxicology, just wash your hands. Really. That's it.
If you're casting, wear gloves. If you're loading lots and lots of mags, wear some gloves (not because it will do anything, just... because). Wash your hands after shooting. The dose makes the poison.
There are plenty of Suzanne-Summers nutcases out there who will tell you that everything is poisonous, and they are right; it's just dose dependent. If I ingest several metric fuck-tons of aluminum metal via eating underarm deodorant, then yes, I might see signs of aluminum toxicity. Same for handling .22 shells; If I choose to grate up the exposed lead and brush my teeth with it, yes, I might have a problem in a reasonably short period of time.
As long as you wash your hands after shooting and wear an N-95 if you happen to be around a lot of lead dust, you have nothing to fear.
