I can see Moduckdoc's point of view on this. Some CA's have already gone non-toxic shot area wide. And it's not a great leap to see them forcing the issue of using lead free single bullets as well. Think solid copper. It never made any sense to me why they (the government) would have a problem with putting something (lead) back into the ground from which it came.

As far as gun/trap ranges that see a lot of shooting, some ranges already reclaim the shot for recycling/resale, so why couldn't the owners of those ranges simply vacuum up the wads for recycling as well?
