A while back, when my buddy and I were at a gun show, he decided to buy some 12 ga. shotgun shells which had one rubber ball. They were $2.00 ea. as he remembered. Yesterday we went shooting and he wanted to try these out. It turned out that none of them had powder and the wad and rubber ball stuck in his barrel and he had to push them out. He ended up trying a few more to see if maybe the one round was bad. They all were bad! I guess, even after all of these years, I'm naive enough to think that gun folks are a cut above and not just a bunch of carnival cheats. Anyway, be forewarned if you come upon one of these vendors at a local gun show.
