[QUOTE="Harry Knutz, post: 2634905, member: 123671"] Remington firing pin holes are already close to being too big from the factory. The crater is the primer flowing into the hole, Over time it gets larger, It's nothing to get too worried over until it pierces primers, Then you need to stop shooting it until it's fixed by bushing the firing pin hole, If you don't you will get primer blanks inside of the bolt and at a bare minimum it will stop igniting the primer, Or it will break the spring. When throats get damaged, Groups start opening up as a result of the jackets being damaged or torn, That's why you will get 2 in the same hole and then it will spit one 3 or 4 inches over. And you're primers are not flattened, I don't think your load is over pressure at all. [/QUOTE]
