[QUOTE="Black Hat, post: 3047376, member: 109036"] I've had this problem with a .243AI years ago. I put it down to the thicker shoulder brass migrating into the neck after many cycles of sizing and firing. I can tell you that reaming and trying to push the donut to the outside and turn it off doesn't work, creates more inconsistency than it solves! Best thing to do is to just size 3/4 of the neck and don't size anywhere near the donut, make sure a projectile will pass though the fire case first however. How many firings did you have on that brass, I was pushing the envelope, so just ditched it and started to bump sizing and neck sizing when needed, not FLS all the time If you are not loading the projectile down into the neck shoulder region it shouldn't create any concerns anyway.
