Yes, but easy to mitigate. Wear cloves and a particulate mask when cleaning/sorting brass from vibratory media. I've found Acme Bullet Co. has great coated bullets, so touching lead isn't a big issue. Just use your head and you're good to go.Is there an increased potential for lead exposure during your own loads? Or any way to just avoid that at all? Its been awhile since I looked into it, but I thought it was from cleaning the brass yourself.
