I have a WWII Russian PPSh-41 submachine gun. The original caliber is 7.62x25. First I had a 9x19 barrel made so I could shoot 9x19 and conserve my stash of Norinco 7.62x25. I wanted to convert it to a cartridge like the 9mm Mauser Export, which was said to be one of the best subgun cartridges, but after WWI, 9x19 was adapted by most European countries. I learned of the 9x23 when I was discussing this with an IPSC shooter. Almost the same dimensions as the 9mm Mauser Export! And the thicker web appealed to me since, with the PPSh, I needed a hotter load than normal. The 9x23 really rocks in my PPSh! A 71 round drum in 9x23 in full auto is quite an experience. :grin: Shooting 124 gr TCJ with 8.2 grs VihtaVuori 3N37 at 1551 fps and a cyclic rate of 1118 rpm. What a hard hitting round! Hotter than a .357 Mag. It really takes the steel down with authority! I have experimented with different powders and bullets (95 gr, 124 XTP and 147 gr).
Have a Star Model A that has a custom made piston type recoil rod that I shoot 9x23 through. Usually download the rounds for this pistol as a safety measure.
