Note the shoulder of 9.3X57 has a width of .433 and is 1.805 from the base (in inches).
The 9.5X57 (Eley drawing) shows a shoulder of .455 at 1.825 from the base. I have some original DWM 531 of 1926 manufacture that measures .453 at the shoulder.


The 8X57 Mauser is narrower still, but not as low.

My 9.3x57 had the 1.825" or 1.824" length of body to the top of the shoulder, some .019" LONGER than the parent 8x57 case I used.

This excessive headspace had to be taken into account when making my 9.3x57 brass, which was not a bother or problem.

The standard shoulder measurement of Ackley IMP standard cases, is .454", same as my 9.3x62 Oberndorf Mauser's chamber and the 9.5x57 of this thread. I find that quite interesting.
