[QUOTE="Daerider, post: 1487583, member: 106638"] When I cut new chambers for belted magnums, I normally set headspace on the belt based on the average measurement of the lot of brass that i intend to use for the life of the barrel to minimize stretching of the case head body junction upon first firing. Since I do not have my shipment of ADG brass in yet, I thought I could get started with some measurements taken from random samples of brass. But based on the variance of measurements that I have received, I think it is best to short chamber the barrel and finish it by hand when the brass arrives. Thanks for the info! [/QUOTE]
