Whenever the subject of misfires comes up, it most often seems to be attributed to the primer being seated either too deep or too shallow in the primer pocket. I fully understand the problem with seating primers too shallow. The firing pin expends its energy driving the primer further into the pocket instead of crushing the primer and igniting it.
But, I don't understand the other oft stated cause, that is, primers being seated too deep in the primer pocket. How can a primer be too deep in the primer pocket? (Unless the pocket itself is too deep.) Is it not desirable to have a primer bottomed out in the pocket? I have even seen references to some folks seating each primer until they feel it bottom out in the pocket. What am I missing here?
