[QUOTE="Hired Gun, post: 106474, member: 1290"] Every chamber is different so trying to compare measurements is meaningless. The new brass measurement also means nothing. Your fired brass verses you chamber measurement are the ones that matter. If you dead set on bumping the shoulders back then I would only go a .001-.002 under your actual chamber size. The farther you set them back the quicker you will have a head separation. My dad was big on full length sizing and he would have a separation between 3 to 5 firing on his 7 Mag. It drove him crazy if our handloads wouldn't interchange between our two 7Mags. To deal with it he just threw them away after the 3rd firings. Once I moved out I now call the shots. All my rifles shoot best with fired formed brass. On belted cases I just ignore the belt. I have belted brass with over 20 firings and they don't ever get tight due to the belt. I haven't bumped a shoulder back in 15+ years. I use Lee Collet dies on everything I can. The only thing they touch is the neck. If you feel you must bump a shoulder back I would do it by feel, just only bumping enough to get them to chamber decent. If your bolt is closing hard you might be a little high on operating pressure. Even my Weatherby's that have very little camming action close easy. A Stoney Point guage head space guage is a novel toy but I have never felt the need for one. [/QUOTE]
