Autoprime
I've mangled my fair share of primers (mostly WIN, but CCI and Federal too) in a Lee Autoprime over the course of the past 10 years and thousands of rounds. I've had to pry some out of the case with a knife and have never had a kaboom with any primer of any brand. I'm pretty careful when doing this, but having seen the condition of some of the stuck, mangled primers, I'm somewhat surprised none have gone off.
I would definitely hate to see a chain reaction in a primer tray or tube though - one bang would be plenty.
I've gotten to the point of buying mostly WIN primers lately though, for consistency and compact storage. WIN and CCI seem to be much easier to find around here too.
