Hutch,
If Buffalo Arms doesn't have them, CH4D can make you a set. If you can "worry" them down small enough to chamber, you can fireform them to fit. Sizing in 25-20 sizing die with the expander assy removed might do it. You might have to start with 32-20 die.The cases will look "funny" with a very long neck,they will come back in fireforming.If still too tight, the wrap in paper and drive it in trick may work. Once fireformed,you may be able to load with 6.5x57 or 55 dies by neck sizing.You just wouldn't screw the die all the way down.
