[QUOTE="Tac-O, post: 2724985, member: 109994"] After fireforming and measuring the headspace as I'd described above using tape on the case head, I didn't push the shoulders back when sizing unless the case base to datum measured longer than the others. So if I remember correctly, on the first sizing I only pushed shoulders back to make all of them the same with that batch of 25 cases, which was 0.002-0.003 short of what I measured for headspace. In this case, I measured base to datum with zero headspace being 1.812 and all my cases after sizing the first time were 1.809-1.810. I think I only had a few where I pushed the shoulders back. The other part of your statement that they don't grow when firing... On subsequent firings after the initial fireforming, I do see a small growth of maybe 0.002 or 0.003 in length. On the last round, I trimmed them to 2.162 and after firing before sizing they were 2.164-5. Not nosler? [/QUOTE]
