Dumpster diving is not above me. Recently at my club in my usual trash can check I found about 60 lbs of ammo that the local police dept decided to destroy by pulling the bullets with pliers. They dumped the powder on the ground in one pile. Much of the primed brass is still useable. The shot shells they cut above the brass also dumping the powder. I found a number of antigue shells destroyed some loaded with black. I salvaged the shot,buckshot, slugs and fiber wads. Seams to me that a better way to destroy shot shells would be to shoot them,perhaps even some sort of training with them. But we are talking about New Jersey cops here. Better to risk ones hands with a razor knife so if they get cut they can stay home on dissability at the taxpayers exspence.
