I work in an industry where I’m always exposed to lead. I also target shoot as often as I can though the last few years have been less than I would have liked.
I have my Doc every couple of years run a blood test emphasizing lead exposure (heavy metals test). So far I’m lead free but YMMV.
This is my experience. I have been a firearms enthusiast for over 50 years. Target and silhouette shooter. Reloader and bullet caster. Salvaged lead from tire weights, batteries, linotype, and a any and everything i could find, because I shot a lot, and was on a budget most of the time. 73 now, still shoot just about every day. Lead levels are normal.
What is “YMMV?”
