[QUOTE="AZShooter, post: 927462, member: 5219"] tdean, I would call both Gunwerks and Hornady and tell them you are having primer pockets enlarge in one firing. You could have a bad lot. Certainly worth a try. You are experiencing pressure that is certain. Heavy ejector marks, heavy bolt lift and loose primer pockets point to too much pressure! If you have any virgin brass left try a mild powder charge of perhaps 66 gr of H-1000 and see how the brass performs. If those pockets become loose then the brass would have to be soft. I started a post in the reloading section regarding wall thickness of the 7 LRM. Can you measure a loaded round's neck OD for me and post it here or if you are through posting about the LRM, could you PM me instead? Thanks Ross [/QUOTE]
