I had to dispose of a box S&B .45ACP two Sundays ago at my local range. Gave the ammo to the range master so that he would take care of it. The whole box was bad. It was a problem with the casings. All the casings seemed to have been warped around the edge as if they had been pressed too hard when loaded. I hadn't noticed it until I shot two and the thrid jammed so hard I had to pull on the slide with both hands to get it to open. The guy next to me asked me to see my gun and ammo and he was the one to point it out. I then compared the ammo to some Win USA ammo and could see the difference. To make sure it wasn't the gun I shoot a box of Win USA and had no probs. From know on I'll stick to Win, Rem, or Fed.
