TsNIITochmash launches a series of cartridges of increased power caliber 9X21 mm

Serial production of high-power cartridges of 9X21 mm caliber starts in Russia. According to the TsNIITochmash press service, the Institute is currently preparing for the production of 7N42 and 7U4 cartridges for the Udav pistol.


TsNIITOCHMASH is preparing mass production of a nine-millimeter cartridge with a bullet of increased penetration (index 7H42) and a nine-millimeter cartridge with a reduced bullet speed (index 7U4). Both cartridges are made as part of the developmental work of the Boa constrictor and are intended for the nine-millimeter self-loading pistol of the joint venture, better known as the Boa constrictor

- said in a statement.

The first cartridge 7N42 is a cartridge with increased penetration, capable of penetrating body armor of the second protection class at a greater range than analogues. The cartridge provides a high lethal effect and is one of the most powerful cartridges of 9 mm caliber.

The 7U4 cartridge is a cartridge with a reduced bullet speed, designed for flameless and silent shooting. A feature of the cartridge is the cutting edge at the front end of the core, formed by two flat faces, and increased mass. Although the speed of the bullet is slower, the features make it possible to penetrate the second-class bulletproof vest, while maintaining silent and flameless shots.

When exactly the production starts, the press service of TsNIITochmash did not specify.

        The 7U4 cartridge is a cartridge with a reduced bullet speed ... Although the bullet speed is slower, the features make it possible to penetrate the second class bulletproof vest

        Damn it ... I didn’t know that it was possible. But just a special core shape

          author -> author -> author burns. No cutting edges when breaking through. There are two facets of the core, with the help of them the area of ​​contact of the core with the punctured mass is reduced. Hence, enormous pressure arises at the point of contact and the past of the armor occurs, well, not cutting

          7N42 with the so-called chisel sharpening of the core. So in the official literature it is written about 7U4 that I did not find anything in the open literature, but it looks like the bullet itself has the same shape as that of 7N42, but the weight of gunpowder is smaller. Because of what, the bullet speed is subsonic, but because of its shape it is able to penetrate bulletproof vest.

            Not the fact that the same form. The bullet is more massive, but the caliber is the same. So, most likely, the bullet is longer. And since the cartridge is of the same dimensions, it is natural that there is less gunpowder - less space for it in the sleeve.

      Are you talking about?
      Cartridges of this caliber have long been produced and the corresponding weapons are in service. True, all further special forces did not go. And these cartridges will not go further than specialists.
      But the Army is rearmament in PYa, other pistols (PL-15, GSH), although successfully passed state. tests, and adopted, but somehow they are in no hurry to replace the existing ones.
      The same is true for automata. Instead of AK-12, they began to supply AK-74 in the body kit.
      It is right. The gain from AK-12 is not too big, and the cost is decent. And in general, I won’t be surprised if in the near future we learn that small arms of a larger caliber are being tested, capable of piercing bulletproof vests of all protection classes at great distances.

            You can make a “Knight” for him. In most cases, the power of the Ak74U is not needed. And 9x21 will provide an opportunity to shoot with dignity and with guns. Probably the TT cartridge, as it is already forgotten undeservedly.

              Too specific weapons. There is no particular need for it. For the army, there are enough AKs and pistols, for pilots and crews of armored vehicles the AKs of the corresponding modifications and pistols are also enough. For specialists, it can be when cleaning buildings, and the use of such a powerful cartridge in the city that can flash the walls of buildings is no worse than automatic or machine guns, if you just don't give a damn about the environment, then it is quite possible. In addition, the weapon itself is too expensive as ammunition.

                The Russian Federation took the path of the MTR and all special forces to solve internal and external problems. And this requires a specific weapon. And not the Ak-74 for everyone. Here in quarantine at all posts of GAI officers added special forces soldiers. Why do they need full-time Ak74M in the city? Or a 9x39mm VAL with a silencer?

                  All the same. Rosgvardeytsy stood at the posts packed as for battle. It was not clear who they were going to fight with.
                  But this is from another opera. By the way, our gayts stood without weapons, then apparently they ordered they armed with pistols with the PM standing, and they also had the PP-2000, but they were also not given them. Although for the time of patrolling in the carriage one always travels with the PP.

    And how will the presence of such cartridges affect the wear of the gun barrel? Indeed, high armor penetration is a higher bullet speed as well, and this is natural, and increased barrel wear. And, with the frequent use of such bullets, this will affect the accuracy of the shooting for the worse.

      The barrel wears out from the number of shots more than from the speed of the bullet in the barrel.

      You have incorrectly linked the dependency chain.
      Barrel wear occurs with increasing pressure, which is necessary for high speeds.
      And in pistols, the speeds are always low - do not compare with long-barreled weapons, with a smaller ratio of sectional area / weight of the bullet.

Automatic carbine for crews of rear equipment. All communications / air defense personnel. Self-defense weapon based on a carbine for aircraft / helicopter crews. Promising cartridge.

          It’s much more complicated. I think one cartridge is better on the battlefield. And the crews should equip the infantryman with standard weapons. The crew of a damaged tank or infantry fighting vehicle on the battlefield will connect with the infantry. And you can share ammo and the same range. Although this is my opinion and I do not insist on it.

      Greetings, the 7U4 "subsonic" cartridge is suitable for sure, there can be no increased pressure, there is no clarity on the 7H42 cartridge, if it has the same bullet weight and speed, and penetration is increased due to the shape of the core, then most likely, otherwise the story with the PMM cartridge will be repeated
