Everyone who shoots should get a baseline blood lead level. Mine got up to 28 shooting USPSA outdoors 5 times a month running Bear Creek Moly bullets. I switched to Bayou coated, and it dropped to 8 in four months, then down to 6 in 6 months, about the same as for guys shooting FMJ's and JHPs. There is still lead from the lead styhpnate in the primer, but 99% of lead comes from the gun exhaust you breathe in, and if you RO allot, all the other shooters gun exhaust. Lead cannot go thru your skin, and if you just happen to handle steel during setup, and forget to wash your hands, that fractional amount will go right thru you. While spent primers may look nasty, the lead that was there is completely oxidized during ignition. You may have thought you had lead poisoning, but there should have been other symptoms to go with it. Severe migraine headaches, extreme sensitive to light, throwing up, diarrhea, black lips, black finger nails. Over 60 and you would be put in the hospital for chelation, which takes up to 5 days. Don't do this at home, because chelation rips out all the heavy metals, including potassium. Shooting cast lead, shooting indoors, shooting 2,500 rounds a month, yea, you'll get some lead. Shooting coated or plated or FMJs, outside, 200 rounds a month, no, you would be around a 2, if that. Casting lead does not present a problem as lead has to get to over 1,200 degrees to vaporize, and it melts at only 625 degrees. A lead panel will also test for mercury and arsenic. So get yourself tested and then you will know.
