7.62 x 25 mm TT
Encyclopedia : 7 : 76 : 762 : 7.62 x 25 mm TT
The 7.62 x 25 mm TT is a bottle-necked pistol cartridge widely used in former Soviet and Soviet satellite states. Actual caliber of bullet is 7.85 mm (.309 in)
Design
The cartridge is basically a Soviet version of the 7.63 mm Mauser. They are very similar: in fact some weapons can use both cartridges interchangeably, though this is not recommended. 7.62 Tokarev is usually much more powerful than its Mauser counterpart and can damage any firearms chambered for 7.63 mm Mauser. The Czech version of this cartridge has 25% higher pressure loading, meaning that it produces significantly more velocity and energy than other common loads and may present a danger to the user when fired from weapons not specifically designed to use it.The Soviets produced a wide array of bullets for this cartridge, for use in submachine guns. There are armor-piercing, tracer and incendiary bullets. This cartridge has excellent penetration: It can defeat lighter ballistic vests (class I and II), but that makes it unsuitable for police work because of the recoil. Although most firearms chambered in this caliber were declared obsolete and removed from military inventories, some Russian police and special forces units still use it for its superior penetration, rather than the more popular 9 mm Makarov ammunition in current use.
Beware of firing military surplus ammo headstamped "* 10 52 3" (reading clockwise). There have been reports that these rounds were manufactured improperly, and could result in damage to the gun and injury to the shooter.
Some firearms that use this round are pistols Tokarev TT-33 and Vz 52 and submachine guns PPD-40, PPSh-41, PPS-43 and K-50 m.
It is becoming increasingly popular to custom load 7.62 x 25 mm with .30 caliber sabot rounds with .22 caliber 55 grain (3.6 g) bullets -- this is known as .223 TIMBS. Muzzle velocities in excess of 2200 ft/s (670 m/s) have been obtained with this method. These speeds are seldom obtained with a handgun; usually, the longer barrel of a rifle is required.
