Artic:
I ended up lubing the cases well and running a couple through the sizing die without a shell holder. Used a .22 Hornet shell holder to run it up all the way into the die. Ran it out with a metal dowel rod that fit the case and, voila, it chambered perfectly. A friend is going to face off a m/m of the bottom of the die in hopes that this will solve the problem. My fired brass was out of a Rigby hammer 450 3 1/4 Nitro.

470evans:
I had thought that maybe the crimp would be a problem. I put a crimp on the brass that I had initially inserted but they still did not want to chamber. That's when I called my friend and he made the suggestion to push the case up the die without the holder.

500Nitro:
I am taking your advice and dedicating brass to each rifle. No sense in reinventing the wheel.

Generalwar:
My friend that will be working on the die will be slugging the bore and utilizing a "v" something-or-other and a point indicator something-or-other for the 7 land/groove. Once I have correct measurements then all set to load, if bore/groove diameter is correct for caliber.
