I've been having troube with my 7 mag brass swelling just ahead of the belt after 3-4 reloads. All the pressure signs say everything is fine and the chrony #'s are fine. I've heard of this before but I've read many times that 8-10 or so is the norm. I full length resize but I do not push the shoulder back. Any ideas? They tend to hang in my rifle just ahead of the belt about 1/8", like a slight bulge. I was perplexed for awhile as I thought it was pressure signs but no,just the case.
