[QUOTE="MagnumManiac, post: 1089992, member: 10755"] I would run it through in 2 steps, first I would neck down to 7mm, then I would run part way into the 264 die with the expander removed, only just start to push the shoulder back, size down in stages in this step if you can, rotating the case a 1/4 turn between sizing helps, then check the neck length and trim before final size and neck expansion with the sizing button. Final step would be to measure neck thickness, I believe it will be thicker than regular 264 Win Mag brass. If you do this, tell me the OD of your finished necks and I'll compare to my 264 brass I have here. BTW, I did this, 300WM to 270 Weatherby with mixed results. No matter how slow or how much or little lube I used, the shoulder area would get wrinkles in it. EVERY CASE had them, some far worse than others. It was far easier to use 7mm Rem Mag brass and fireform to suit, in your case, all you need is to run it through your 264WM die, seat bullets and shoot. Let me know how you get on.
