I was target practicing with some rounds i loaded about a year ago. fired a few shots, no problem. Then i loaded another round, pulled the trigger, and 'click'........ no bang, no pop, nothing. i ejected the cartridge, and the bullet was lodged a few inches into the barrel. And a bunch of unburned powder spilled out. I'm puzzled that if it didnt fire, how did the bullet get lodged in the barrel? And why didnt it fire?
