[QUOTE="longbowelk, post: 1210308, member: 41272"] For what it's worth. Here are the measurements I took with a dial caliper. The four lines are where I took them. Starting at bottom and going up. On the unfired 280: .463, .463, .462, .460...the Fireformed case before firing as 280AI, .4635, .466, .466, .464...same case fired as 280AI, .4635, .469, .467, .465 Last firing using 162 bullet at 2.881 to ogive (approx. .008 off lands using 48 gr of IMR 4350). Will post headspace next once I get the numbers. [/QUOTE]
