You can fire form 30 06 brass and trim it down to 57mm.
Have you done this?
It is my understanding that the 'old school' method of reforming .30-'06 to 9.5X57 involved several steps with expanders, dies, trimmers... .
I have used fresh .35 Whelen brass, run once through a two die RCBS die set, trimmed to proper length.
Left to Right: New 9.5X57 from Reed's of Oklahoma, One of my old handloads from fresh .35 Whelen brass reformed with RCBS dies and filled with Hornady 3715, Original (1926 dated) DWM531, Once fired brass from one of my '.35 Whelen' handloads.
