[QUOTE="TMR, post: 142171, member: 5819"] Need a little help here....I was having a little bit of primer cratering on my 243AI. It was happening even with the fireform loads, so I figured it was the firing pin. We looked at the firing pin and it measured a little undersize, and the hole was beveled. We drilled the hole out so the the Holland pin would fit. Problem solved, so I thought. Now, I get a raised protrusion on the primer. It looks like the primer is flowing back into the firing pin hole. Still does it even with the fire from loads. Dave Kiff suggested to slightly flatten the firing pin and that would probably cure it. First shot, primer looked perfect...second shot, slight cratering....third shot, slight cratering w/protrusion. I am at a loss here. Do I need to go up in the powder charge? Change primers...it had been working fine (except the slight cratering) up until we changed the firing pin. I am using CCI200 primers...remington short action, Lilja barrel....
