Lead as found in bullet form is not particularly dangerous unless one is shot with it. 2 friends who do LOT of bullet casting and shooting have both tested normal for lead. One was tested because at the time he was casting lot of bullets in a poorly vented garage.
Lead in bullets is not lead acetate (what poisoned the Romans since they used it to sweeten their wine) or lead as found in paint or other such compounds that is easily absorbed by the body regardless of all the lead hysteria BS you hear.
This is basically just an another anti-gun/anti-shooting/anti-hunting "panic the public" ploy.
If you are worried about lead and you have a well or even a public water supply you might have your water tested. It might be more dangerous than handling lead bullets.
