Have you recently messed with your action screws?. As you already know,Factory ammo is neither full length sized or fire formed it is in some odd ball inbetween stage. If your rear action screw is set to tight a bolt not closing is excatly what happens. Remember-tighten front action screws first then the rear. Never rear first
