I have searched all available literature for original ballistic data of the 9.3x57R/360, but did not find anything meaningful.
In those days - before 1900 - ballistics were not developed very much.

Now I load for my rifle the 12.5 gram / 193 grain RWS bullet for the 9.3x72R, to a muzzle velocity of max. 540 m/s (1770 fps).
The rifle is nitro proofed; I would not use that load with a rifle that is only BP proofed.
