Sorry to disagree. I have eaten wild meat most of my 49 yrs. I reload, shoot, reload again. I do not have any special ventilation on my bench. I do not have any elaborate collection system for spent primers.
Several years ago, (12-15) i read an article citing the heavy amount pf lead poisoning around loading benches and why we needed to keep our children safe by having dedicated air cleaning, collection systems, etc. this guy was quoting lead levels on his bench that were off the charts (but he also cast there). Concerned, I got a PMed Tech to help me test mine. I have no idea what the guy was on. No unsafe levels on the bench and barely any registration in the room.
A couple of years ago, they found a concentration of heavy metals in my system. I was tested for heavy metal poisoning. Know what they found? Strontium. Not lead.
Effects of toxic lead poisoning in children includes reduced brain activity and retardation. I have 5 children. All grew up eating wild meat, helping me load and shoot. One has a Masters in behavioral psychology. One is a Vet assistant, one in an EMT, one owns a private day care facility, and my youngest works in a machine shop apprenticing as a machinist. I don't see those awful effects of extreme lead poisoning you have referred to. I don't think it is irresponsible to shoot an animal with a bullet containing lead (BTW, that's the way it is not "lead containing bullets"), although I wouldn't use lead to shoot migratory birds.
For close to half a century I have fished with lead sinkers in my mouth on more than one occasion. Used my teeth to crimp them on or off, had pieces broken off, drank from lead painted containers as a child, probably licked some lead paint chips, etc. I have no more proof, personally, that lead poisoning is any more dangerous than owning guns, except that the government tells me they are the same.
