A threat to the Coburn Amendment

The department of the interior is proposing the banning of traditional lead ammunition for use in hunting in National Parks that allow it. For those who choose to carry a gun into a national park for self defense purposes, this could mean that a traditional lead bullet would land you in hot water if used. I'm not going to go into stopping power, ballistics or caliber wars here. If Mr Bear and I meet in an unpleasant manner, I'd prefer my .500 S&W to be loaded with copper jacketed hollow point lead.
