[QUOTE="brassprep, post: 288061"] I agree with most of what has been posted here, however; most brass that has a neck, will not be "chamber perfect" until at least two firings. Brass has spring back. Before you settle on a true headspace (as this is the question here), fire x amount of rounds once and x twice (utilizing the already mentioned 'chamber as gauge' method) you will find that upon the second firing, you'll be much closer to real chamber size. Some HP 308 shooters believe it takes 3x to fully settle fit. [/QUOTE]
