There isn't any hard science that lead shot kills anything but waterfowl and the science on that is pretty weak as well.
Somebody said steel isn't bad, well I guess it isn't but none of the guys here want to shoot it through their old double guns. My guess is that's why this thread got started, hence it does relate to doubles.
The firearm manufacturers jumped on the lead ban bandwagon because it meant every waterfowler in the country would need to buy a new gun. Once it had their support and the support of liberals it was a done deal. New non-toxic shot rules in every country that has them have been a direct result of this. As the boys from across the water say, they have no proof of any lead poisoning in any waterfowl in the UK at all and neither does any other country that has the same rules. BASC didn't fight it too hard because it sounded good to the public and they're all about public relations. Anything they can do to make shooters look like conservationists and less like bloody fisted murderers to the general populace.
They managed to beat this back in Minnesota recently, hopefully Washington will do it as well. It got through in Alaska because they didn't publicize it and there aren't that many folks to speak up anyway. What stuns me is that the Liberal Republic of Illinois hasn't gone for it yet, I keep waiting for that one.
I hope you boys on the left coast fight it hard all day long. The fight is coming here in the midwest, hopefully we're ready for it.
