A metal detector isn't going to pick up fine lead fragments. Thus far I have read multiple people say they have been eating game meat for years and haven't been poisoned. It would take alot of lead to get lead poisoning, however that doesn't mean that each time you have consumed lead it didn't impair you. Same with with blood levels. Just because you have low blood levels in the present doesn't preclude you from having higher levels in the past. It coukd be much ado about nothing, but until a definative study comes put I am being very picky on how and when I use lead bullets.
The gold detectors I use can pick a shotgun pellet in about 4" to 6" of meat.
The problem is many of the particles are so small and X ray doesn't even pic them up.
