My 700 Rem .308 exhibits a good primer strike, but there is a slight puckering around the dimple from the firing pin. At first I thought it might be due to me lapping the bolt lugs might have changed the headspace a tad by off chance, but I had some brass I fired in it before I did the lapping and they were the same. This is on various brands of primers. There is no piercing, just a little pucker. Oversized hole? Anything to worry about?
