Corn-picker, I think you make some very valid points and we should all be striving to reduce the amount of lead we come in contact with.
NOW, having said that, I was hand scraping lead-based paint off of old homes (sometimes off asbestos shingles), barefoot, when I was a kid. My mom and brothers and sisters moved into foreclosed and abandoned homes and fixed them up my entire childhood. We drank water through old pipes and I even played with molten lead as a kid, making fishing weights and jig heads. And somehow I still managed to graduate college with a 3.4 gpa (probably would have been higher if I didn't have to work so much after class). After college, Uncle Sam gave me tens of thousands of rounds of lead-based ammo to train with and I shot it all, indoors and out, and asked for more when the mags ran dry.
My point is this... despite the fact that we know lead is potentially harmful, the FACT that many of us were exposed to much, much higher levels of lead as kids, and turned out just fine (with arguably a lot more common sense than kids today) is always ignored when the subject of lead exposure comes up.
My grandfather was still farming and ranching well into his 90's and probably would have lived longer if his wife hadn't passed before he did. We think he died of a broken heart, not from lead poisoning, DDT exposure, asbestos or anything else - although he was exposed to all of those things. He also ate eggs and a lot of bacon every single morning, and drank coffee all day long. I know many here can share similar stories.
Sorry for the long rant but I'll be happy to use bullets without lead in them as soon as they perform better and cost the same or less. Otherwise, I'm not interested.
