[QUOTE="Broz, post: 399625, member: 7503"] Hey Guys, Just wanted to follow up and report my findings. I just last evening got to look at the fired cases. They were definatly a bit over pressure. Here is what I found. Slight ejector pin circle was visable on the headstamp. Just enough that a very close look and you could make it out but not enough for hard bolt lift. This is the same exact spot where every pocket leaked, and the only spot. So it is my conclusion is that under this high pressure spike the pocket deformed slightly and let a bit of gas leak out next to the ejector pin. Also, the primers were definatly cratered a bit, not alot but I could catch y thumb nail on it. I punched out the primers and put them on my primer pocket squaring cutter. The pocket are still true and round. I then seated new primers to see if the pocket was enlarged. The new primers fit nice and firm. I also did an inside mic of wall thickess right above the belt to look for a weakened area. None was evident. So I feel they are good to go again. I believe the problem was due to the reduced inner case area of the RWS. This made the % of case fill higher and increased pressure. Also, this was the warmest ambient temps we have ever fired the rifle in. I also believe we were closer to max than I origionally thought. So all bullets will be pulled and new powder charge will be developed. Just wanted to add my findings to the thread in case anyone else ever has a similar issue. Thanks for all the replies.
