[QUOTE="KRP, post: 2343267, member: 9969"] Forget about the 2.1614 number as you're not measuring this or any other absolute dimension. With your comparator you're taking a relative measurement between fired and sized brass. It's possible for the chamber and cartridge to be in SAAMI spec and have as much difference as you are seeing. The next time you fire that case it will stretch to fit the chamber again, so it's also possible that doing this repeatedly will give you problems with the cases separating. I wouldn't want that much difference every time I sized/fired a case so I would adjust the sizing die. If the fired case will chamber easily I would size them without moving the shoulder and fire them again. If you have to move the shoulder that far to get the case to chamber easily I would figure out why and then look into possible solutions. If you are concerned about the headspace then get a gauge/gauges and check it. [/QUOTE]
