Was loading my Charter Arms 380 this morning and after it was loaded I found that I couldn't rotate the cylinder. Trial and error abound. I first made sure each cylinder was clean. No help. Swapped hole with the rounds and still couldn't rotate it. Next I took my digital caliper and started measuring the case lengths. WOW! I found one case that measured over .7. Normal case length is .680. Install another round and all worked as it was supposed to. Browning ammo and never fired cases (new out of the box). Live and learn. As an old maintenance officer of mine used to say: "If it ain't hornets, it piss-ants. Always something to aggravate you."
