Awhile ago NRA went on a bender and set out to convince legislators that slug guns and muzzle loading rifles are just as lethal at the same ranges as centerfire rifles. Their reasoning was that they could make a case for allowing centerfire rifles. I immediately objected that it was more likely that the legislators/game departments would institute buckshot-only laws/regulations. NRA told me "pooh pooh, you don't know what you're talking about."
