7.62x25mm Tokarev Ammunition
The 7.62x25mm Tokarev cartridge is a bottle-necked pistol cartridge designed in the Soviet Union. It was widely used throughout the USSR and the Soviet satellite states. It is effectively a more powerful Soviet version of the 7.63x25 Mauser cartridge.
The two cartridges are physically very similar, to the point that many weapons can chamber both rounds. However, the significantly higher power of the 7.62x25mm Tokarev will likely lead to weapon damage and user injury. The Czech version is loaded to 25% higher pressure yet, leading to significantly higher velocity and energy and to greater danger if used in weapons not designed for it!
The Czech ammunition must not be used in weapons not specifically designed for it!
The Starline Brass site
has this warning for reloaders:
This case [the 7.62x25mm Tokarev] is very similar, except for the difference in length, to the .30 Mauser. Due to higher operating pressures, if the .30 Mauser cases are fired with hotter 7.62x25 loads in the ČZ-52, it will tear the neck off some cases. 30 Mauser O.A.L. is .980" to .985" while 7.62x25 O.A.L. is .958" to .962".
At right are three 7.62mm cartridges used by Warsaw Pact firearms: the 7.62x25mm Tokarev, the 7.62x39mm rifle cartridge used in the SKS 45 (Самозарядный карабин системы Симонова) and the AK-47 Калашникова rifles, and the 7.62x54R (rimmed) cartridge used in the Mosin-Nagant rifle (Винтовка Мосина).
Below are some common handgun cartridges, including the 7.62x25mm Tokarev.
Users commonly report that the recoil, report, and muzzle flash of a 7.62x25mm Tokarev cartridge are similar to those of a .357 SIG. The unusually loud report and prominent muzzle flash can be surprising to the unprepared shooter. This round can perform more like a small rifle cartridge than a typical pistol cartridge.

The so-called "Czech Load" is suitable for use only in handguns specially designed for the higher pressure such as the ČZ-52.
However, is the ČZ-52 really that much stronger than other 7.62x25mm handguns? Dimensional measurements do not support this frequently made claim. Click here for some speculation on the ČZ-52's relative strength.
Some reloading experimenters have custom-loaded 7.62x25mm cartridges with sabot rounds using 3.6 gram (55 grain) .22 caliber bullets, obtaining rifle-like muzzle velocities in excess of 670 m/s (2200 ft/s). That would correspond to kinetic energy of 808 J (601 ft-lb).
