[QUOTE="Carey Farmer, post: 2683527, member: 122715"] As other posters have commented, belted magnum cases are typically 15 thousandths or more short of chamber length, so the front of the case gets work-hardened a bit upon first firing. I anneal .264 Win Mag cases with the flame pointed at the case wall / shoulder junction (rather than at the shoulder / neck junction) to help soften the front of the case. After the first firing, I anneal and resize but shoot to bump the shoulder back only to the same length it was when it came out of the chamber (resizing the case diameter causes the case to grow a couple thousandths in length). With this approach, my belted cases are typically fully fire-formed after the second firing. After the second firing, I anneal and resize shooting to bump the shoulder back 1 thousandth. I don't know how many firings it would take to fully fire-form without annealing after every firing. [/QUOTE]
