Has everyone forgotten about Murphy's Law? If you don't clean primer pockets, it is not "IF" but "WHEN" you will have a failure to fire, because of a light hit on the primer because of a dirty primer pocket. A failure to fire could cause a Pope and Young buck to get away, or a clean match to go bye bye. Clean those pockets. I always deprime and wet tumble with stainless pins, before that I used a hand primer pocket cleaner.
