[QUOTE="oltmann, post: 166294, member: 6377"] I'm about halfway through the first firing of 50 300 RUM nosler brass in my 338 edge. I'm not ready to make any decisions about the brass yet, but I have noticed one peculiar thing. The primer pockets seem to be way too deep. I use a hand press for seating the primers, and every one is set back below the face of the brass. After firing all primers have moved back to be flush with the brass face, and the hotter loads(bolt slightly sticking) had flowed out of the primer pocket a fair amount. Has anyone else seen this? My guess is this motion of the primer, along with allowing the full pressure of the firing into the bottom of the primer pocket is going to loosen the primer pockets on my brass. Only time and firings will tell I guess. [/QUOTE]
