So I missed the first round of Bertram 6.5 Saum brass and they are sold out. I see they have 7 mm Saum brass in stock yet. I do neck turn a lot of my brass just for consistency and because I am OCD when it comes to my brass. But I have never necked down any brass to a new caliber. I also do not want to overturn the necks to where they are too thin and sizing the case over works the neck after firing which may be possible with 6.5 brass since I am using a non bushing full-length sizing die. So would I be better off to just buy 7 mm Saum brass and run it through my whidden 6.5mm full-length Sizer die, trim to length and turn down the necks to .015 or am I missing a step or two?
