Maybe we should be studying how many crows, buzzards, hawks, and foxes, and other carnivorous critters are dying of lead poison before we worry too much about the lead ammo that we have been using since pre-pioneer days.
I am getting tired of people messing with hunters in every way imaginable. I have a lifetime's supply of loaded lead bullets and shotshells that I suppose they would like to have me just throw away.
And by the way, just because gut-piles are visited by all kinds of critters does not mean that there ever was any lead in any of those gut-piles, although I am sure they will make that assumption in their studies.
Sorry for the outburst, but it seems that there is no end to the harassment of hunters and I am getting pretty tired of it.
