[QUOTE="AaronSkipDavidson, post: 1000772, member: 6373"] We've seen some of the brass come off the line with a neck thickness that is a couple thousands too thick. This makes a loaded neck with too little clearance to chamber neck. We've traced this back in the production process to one of the draw punch dies. New tooling and qc documentation is in place. For brass that has already been manufactured, we are CNC machining all the necks to ensure correct specifications. If you suspect that you may have loaded ammo that is out of spec, measure a loaded round at the neck shoulder junction. If you are over 0.318 please contact us for warranty on your product. We have found two distinct accuracy nodes in the LRM, one at 3100 fps and one at 2975. When we adopted the standard chambering and 7LRM name we adjusted the throat to work with the 180 Berger Hybrid. That combination has not allowed us to load the faster velocity without high pressure. 3050 is achievable, but 2975 to 3000 shoots bug holes all day--its pretty hard to do something different.
