Don't worry about front stuffers , there was a court case that started the whole thing , a 30-06 rifle , a shotgun with slugs and a muzzle loader were tested for down range damage potential in the case of a missed shot . The study said that a missed and deflected shot by a slug gun and ammo had more energy and destructive force down range and went farther than either of the other two. the court case stated that slugs had been allowed with out testing and data to validate the choice . which testing proved to be a bad choice in their opinion . It would seem logical that many states will be revaluating laws soon .
