The new PPU hollow points do work and quite well. 1.5x dia expansion and well over 12 inches of penetration in gel.Most of us in the U.S. shoot these with surplus (or occasional new production PPU) ball ammo. For what it’s worth, although I think in theory this cartridge is begging for a high quality hollowpoint, the hollowpoints I have seen for it have been poorly designed and basically just function like ball ammo anyway, so if I were ever to carry one I’d stick with FMJ. The gun that’s reliable is better than the gun that’s not.
There isn't alot of different pistols chambered for the 7.62 Tokarev cartridge, which is quite formidable even compared to most caliber choices today. In China gangs will frequently choose this pistol because it can penetrate body armor.there are much better firearms for defensive use than TT-33 and all the clones.
My guess would be to replace the magazine follower (the plate the cartridges sit on when in the magazine) and/or replacing the spring inside the magazine.My theory that it is necessary to increase the cartridges angle in magazine!
It would be desirable to know solved problem 8 and 7 owners.
