Was loading some 45 ACP rounds and not paying attention like I should, primer tube ran empty and I had one or two rounds with no primer. Broke out the handy inertia Boolit puller and put one in. Smacked it on a piece of wood (on a concrete floor) and felt like I got punched in the face!!! The cap split in two and the round + holder came back and hit me in the mouth busting both of my lips. I found half of the cap and there is evidence that it had been cracked for a long time. I sure didn't notice it though. I mentioned the incident to a friend and learned something new. he said he always screws the cap on TIGHT the first round as the cap will flex if it's cracked. He didn't tell me but it sounded like he had the T-shirt already.
Anyways, if ya use an inertial Boolit puller check the cap for cracks!!!
