Why? The animals certanly don't care what is stamped on the case. And some IDIOT out there would have another reason to sue the gun and ammo manufacturers cause they are just too stupid to know there A$$ from a hole in the ground. They would order .270 cases and try to shoot them in a 30-06 rifle and whammo. Not a good idea, the anti's don't need any more "ammo" for their unjust cause.
