Lead poisoning of ducks, was a very real problem here in PA, 30yrs. ago, up around Pymatuning. If you shot a duck, and could feel very little meat on the breast, you would find a lead pellet in the gizzard. This area had a large volume of shells fired over it, every year. I agree with banning lead, in a place like that, or a high volume dove field, but I think banning lead for upland, big game, etc. is silly, where the chances of an ingested pellet are very remote.
