Bismuth works just fine Mr. Lowell.

In Tennessee lead has been banned on National Wildlife Refuges for several years for all game. Some still allow lead for turkey hunting only. I don't know that the Humane Society/Peta had any influence on their decisions.
They started trying to ban lead shot in the 1920's it took about 80 years to be banned. I don't think the Humane Society or Peta was around back then.
No doubt Lead shot will eventually be banned.

I just hope the ammo companies will get the price down on the alternatives.
