I had some 300 WSM rounds that were too high in pressure. I was pulling the bullets to redo them, using an RCBS kinetic puller. I was happily tapping away on a brick when a primer fired. It blew out of the primer pocket and flew across the room. The bullet was about 3/4 of the way out so there wasn't any powder near the primer so it didn't ignite. It scares me to think what would have happened if this had happened on the 1st blow when the powder was back against the primer.
I think I'll go shopping for a collet type puller. I've pulled a lot of bullets over the years with this thing without incident but I'll admit that banging on a live round has always made me nervous.
