[QUOTE="yawn, post: 1210811, member: 13540"] Thanks again. I have the same gauge be it much later vintage. I wonder how they would compare? In My cooper 280ai the bolt will not close completely on the gauge. Im unable to find SAAMi spec 280ai gauges in this part of the world so Ill have to import to complete the measuring but I can say that nosler SAAMI spec brass chambers sweetly and the fired cases measure within .001 of the unfired in terms of headspace. Cooper Arms have told me they chamber to traditional Ackley and the gaugeing indicates they are correct. [/QUOTE]
