I think the 9x23 Winchester is the ballistic equivalent of the 357 Magnum. With the very strong web in the case (50,000+ CUP) you can easily reach 357 Mag pressures. I load the 9x23 Winchester with 357 bullets for my converted Tok.
Clark has handloaded 9x23 cases to have TWICE the maximum charge of the 357 Magnum without blowing up either the case or the pistol.
A quote from one of his posts:
If one can find a 9mm Tokarev barrel, and ream it out to 9x23mm, load with Power Pistol, 158 gr XTPs and 1.4" OAL, then the Tokarev goes to a level beyond the hottest 357 mag.
