I really hoped the 9x23mm Winchester would be better received- especially when WWB could be had for the same price in x23 as x19mm! And the WWB JSP actually went fast enough to expand, too!
CAUTION: The following post includes loading data beyond currently published maximums for this cartridge. USE AT YOUR OWN RISK. Neither the writer, The High Road, nor the staff of THR assume any liability for any damage or injury resulting from use of this information.
a) The most power I can get out of a Tokarev with 7.62x25mm with long brass life is "10 gr Power Pistol, S&B brass [not Starline], 1.316", 110 gr HNDY FMJ"
Recoil is horrific, making this impractical.
b) The most power I can get out of a Tokarev with 9x19mm is " 11 gr Power Pistol, 158 gr XTP, 1.169". [Any brass will do]
Recoil is horrific, making this impractical.
c) The most power I can get out of a Tokarev with 9x23mm is 16 gr Power Pistol, 158 gr XTP, 1.35", Win 9x23mm brass" [Not Starline]
Recoil is horrific, making this impractical.
What does it all mean?
Way more power can be had from the 9x19mm than can be dealt with given the slide mass, the recoil spring force, and the distance of slide movement with respect to the frame. [even though ~ half the momentum goes into moving the shooter's hand]
So there can be no real practical gains from switching to 9x23mm.
Maybe gains showing off over a chronograph.
Here is a Tokarev that I has a 308 Parker Hale sniper barrel that I welded a Tokarev link and chambered with 7.62x25mm.
It can show off over a chrono or show off with 100 yard groups.
But it is not practical.
