I'm the messenger here, not the target.
OK, I mostly reload and shoot plated or poly coated bullets anymore. I used to handle lead/cast bullets when reloading so much my hands and fingers were grayish black.
I have no idy what my lead levels are. Maybe outta curiosity, I'll get it checked next blood workup I do.
From reading this forum link and many others I gather generally it is not casting lead bullets if proper precautions are adhered to, but rather indoor ranges and tumbling brass indoors and handling of fired brass. Picking up brass on ranges (especially indoor ranges) where lead dust accumulates on the floors, although Range workers and those who compete seem to be saying shooting a lot and being exposed to lead every work day contributed to their higher levels.
Seems the primers are the main culprit and the lead residue they leave behind in/on brass and on ranges and the floors/grounds...especially worse at indoor ranges.
I'm not sure why some folks have lead levels higher than others who seem to have the same habits. Common sense and washing up plays a role, but seems to be no particular rhyme or reason for low vs elevated or high levels for some of these posters.
I own a Lyman tumbler with a slotted lid, I don't use that one. I use a solid lid one. I tumble in the garage with door open, but have sliding screens. There is "Dust" when I dump the brass and spin it in the colander basket. Then again there is also" Dust" when I scoop out the kitty liter from my cats liter boxes.
I read a lot of theories and some actual reductions in lead tests by those who either stopped going to indoor ranges or altered their methods of tumbling/handling brass and hygiene habits.
Some say breathing "Gun-smoke" on any range is enough with or without exposed lead bullets, especially where it is concentrated indoors is the culprit, some say even outdoors shooting in matches and what not. Especially bad for range workers.
I don't have any conclusive evidence to point to one way or the other. It does seem tumbling brass and touching and breathing the brass and dust is believed to be a big factor in their conclusions.
And primers are a big concern of lead contamination. Now whether breathing in gun smoke which may contain particles from exposed lead bullets and fired primers or handling fired brass to reload is worse, I dunno. Hard to say from what I've read. Seems high concentrations on ranges expose folks the most and indoor ranges are the worst, no matter how high speed their ventilation system is.
Anyhow, read here for some comments and links from the S&W forum.
So just curious what y'all s opinions are.
Knitepoet says his lead levels are good and he cast lead bullets. I know some fishermen had high lead levels from making/handling lead sinkers. Any amount of lead ingested into our bodies is not good fer us........especially the hot lead type....... like from being shot................
