Pinot, in the old loadings the x57 approximates what you might think of as a "heavy bullet .358". But in a modern action or 98, it is nearly the equal, and with bullets of same weight, maybe the equal or better in terms of muzzle velocity-100 yards at least, the x57 case being between the two .35's in volume and the expansion ratio larger for the 9.3.

As for Mak bullets, sure. Many are .364 diameter tho, and for such undersize bullets stick with jacketed, but you are right...like the revolver bullets in the .35, the Mak bullets are applicable for the 9.3. Strike another advantage from the list of .35's!

Some 9.3x57's have overbore barrels common to some other guns of the 20's-40's, being as big as .370 as reported on the Swede forum and here...Daryl. My HVA 146 is .369, my 46 is .367/.368.
