[QUOTE="stanley52, post: 877873, member: 62465"] Ok so I have a 280 AI that I have developed some fantastic loads for, but I continually puncture primers. My original load was 60.1gr H4831sc 168gr bergers, and CCI 200's, and there were no pressure signs except I kept puncturing primers. I sent my bolt in and had it bushed, still getting some punctures, so I dropped the charge to 58.5 which is only .5 above Nosler load data max. Still punctured primers, although the hole is smaller. I say again 0 pressure signs other than punctured primers with either loads. I haven't remeasured the firing pin protrusion but it was bushed by Score High so I'm sure that it is fine. I called CCI and a tech told me to switch to their BR2 primers, he said they had a thicker cup? Everything I have ever read or heard says they have the same cup, and are just held to better quality control. Maybe the material is better? Any thoughts on this? I have also heard magnum primers are tougher. If anyone has some advice please share.. Thanks ahead of time. Can't post pics right now, can on Sunday. [/QUOTE]
