I could see restrictions on steel core on the pistol ranges, but what are they gonna do when the guy with the .32 H&R Magnum wants to go ventilate some paper? .32 NAA? 9x18 Ultra?
If someone wants to shoot their .357 Maximum tungsten core ram buster silhouette ammo, they can go over to the rifle side, but don't make me buy "range special" .45 ACP that my gun may not like...
