Well, it'd sure be nice to be able to convert scrounged range pickup .308 brass to the shorter 6.5 Creedmoor! BUT, after trimming to length and resizing, the shoulder material of the .308 case making the new 6.5 CM neck........is too thick. The seated bullet expands the sized neck so that the outside diameter is too big by a few thou to chamber in my new Savage 10T-SR. Sixty-plus years of reloading and I don't know how to 'outside turn' the case necks. DUH! Can someone here please explain how to go about it? Is there a special small tool? I have a Lyman case trimmer, if that's any help. My pal has a great big lathe.
