Instead of using 9.3x74R cases, you might also start with .405 Winchester or .40-70 Sharps Straight. Base diameter of the .40-70 should fit nicely, no lathe turning needed.

True 10 mm bullets (app. .394) may be troublesome. In any case, the bore dimensions should be taken from a lead slug, I believe.

Defining the original cartridge is one thing, "for the books". But you do not need the original name to make the piece shooting again - all the information you need is in the rifle.

Have fun with this great rifle!
