I do not know if the 9.3 will launch a 225 at 2700, if it were available or remanufactured; but this is about tops for a .350RM (20" barrel) with even a bit more capacity than a standard .35W. The NP 225 that I am using as my general purpose .358 has a BC of .430. I think that the .35s vs.the 9.3s results in the same conclusion that the .33s vs. .35s debate does the smaller bore can pretend to be a longer range smallbore for medium game better than the larger bore. Using a medium to do a mediums job they will all be very close for near capacity cases at like pressures. The .35 in any case from the X57 to WSM is a great mimic from .38 spcl to .35 Rem. to full throttle with with readily available bullets suited to those velocities.

The 9.3s are great mediums that and the svelte little M46 are why I own a 9.3x57, but I just do not see them as being as versitle of a mimic as the .35s. Only a certain type of reloading loon even cares about such things, but some here are even "sicker" than me and even make bullets from other diameters and spent cases.

The .350RM and the .35W use their expansion ratio and essentially equal capacity to give you a sort of freebie of more bullet in that that they launch bullets of like SD and BC as an '06 at like velocities. The 9.3x57 as you point out, if loaded to the like pressure in like rifles, can use ER to compensate for less capacity; but BC and SD suffer.
