[QUOTE="drbill, post: 812066, member: 11198"] I had a similar problem with a RCBS die and a 7mm Rem mag. The shoulder of my brass raised up with my set of RCBS dies. I called RCBS and they had me send them 5 fired cases to them and my dies. They sent back a 7 RemMag small base die for free and said I needed this die for my Browning Abolt. Apparently Abolt chambers are "differernt" and it is a know problem. The small base die worked the area above the belt better but the shoulder still raised up after sizing it (instead of being bumped back). I bought a regular redding die and it did the same thing. I tried a set of regular LEE dies and I finally could get the shoulder to bump back. But I also now need to use the Innovative technologies belted magnum collet die every shot. A "russian character" wants me to cerrosafe the chamber. I should but I have it shooting so good with the technique Im using on this gun I don't want to change anything. I do get case head seperation around 10 rounds. Have you checked to see if the shoulder is being bumped back? I worked my way down 1/8 or less and could never get the shoulder back with the RCBS dies. What gun? [/QUOTE]
