[QUOTE="Bart B, post: 613408, member: 5302"] I asked SAAMI about this some years ago when I started reloading for my first belted magnum. The rep said most cartridge brass starts extruding into bolt face cutouts (ejector holes, slots, etc) at about 65,000 CUP. If any signs of it happen, you're near the edge of the safety cliff and you better back your charge weight off if safety is any concern whatsoever. The picture clearly shows signs of it. Cutting your charge back 2 or 3 grains may be all that's needed. Maybe more. Depends on how much of a safety margin you want. [/QUOTE]
