Before you do anything, if you haven't already, make sure you really have light strikes. The best way to do this is to chamber a fired shell and pull the trigger. This will show what the true firing pin strike is. With a live shell, the powder explosion goes off, swells the case out to the dimensions of the chamber in all directions, the bullet resists going forward, and the primer tries to become part of the breach face! If the load is a little "hot", the primer tries to go in the firing pin hole and pierce itself on the firing pin. Something like that?:) So, when the case is ejected, the primer has been through too much trauma to tell if it is a light strike or not. It could be, when you drop the hammer on the fired case, you may have a "huge" pin strike:)! Good Luck..... Jim
