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.

Reached the production stage. Good.

Increased power will show itself well during the assault on Sauron.

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

[seregatara1969]

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

[sen]

going past the armor, well, not cutting

They meant Kevlar, not metal.

"Our specialists have developed a core in the form of a chisel, two-sided, which does not push apart the fibers of the body armor, but cuts them" - Maxim Popenker

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.

[YOUR]

Maybe so.

[Zaurbek]

+ increase in bullet weight.

[YOUR]

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.

[Zaurbek]

It seems to me that such a cartridge will work well for PP. Ricochet less. But something new PP is not visible.

[YOUR]

As for ricochets, I'm not sure, but there is a SR-2M "Veresk" PP for this cartridge. But again, it is produced or produced in an extremely limited series and only for the FSB

[Zaurbek]

You can also make "Knight" for him. In most cases, the power of the Ak74U is not needed. And 9x21 will give you the opportunity to fire with dignity and with machine guns. Probably the TT cartridge, somehow forgotten already undeservedly.

[YOUR]

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.

[Zaurbek]

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?

[YOUR]

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.

"Increased Might" is just like the Lord of Darkness

"Power" - the term of the cumulative damaging properties of a projectile (or cartridge), official, not jargon and not a mistake

Reduced speed or slower speed? How to logically pronounce or write?

[military_cat]

And it reminds me of an automatic transfer from aliexpress. "Good buy high quality high power ammo"

[bobba94]

The editorial team of VO was offended and threw cons. But ..... after 10 years, the forces will equal, that is, the number of victims of the exam among journalists and readers will be equal, the problem will disappear, there will be no minuses, but there will be happiness for all.

[Thrifty]

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.

[Svetlana]

Affects. But if they start production, then everything is within normal limits.

[seregatara1969]

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

[Genry]

Quote: Thrifty

high armor penetration is a higher bullet speed as well, and this is natural, and increased barrel wear

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.

[The leader of the Redskins]

As I understand it, we are talking about not large (compared to army) orders.
Joy of commandos and headache (extra nomenclature) to quartermasters)))

[Mountain shooter]

Powerful pistol, and powerful cartridges. A worthy successor to "Vector" ("Gyurza") ... this was not lucky, got into the 90s and was produced in small series ... Sighting range 100 meters! A rare sighting range for pistols ...

[Pereira]

A large aiming range is good. What hit range?

[Mountain shooter]

Quote: Pereira

A large aiming range is good. What hit range

Serdyukov himself (the author) was hit in series by 100 meters on the chest target. A well-known fact ... Of course, not an automaton, but ...

[Pereira]

I suspect he's not an ordinary shooter.

[Mountain shooter]

Quote: Pereira

I suspect he's not an ordinary shooter

So the gun is not for a simple shooter. Simple and from PM to 30 meters in the chest will never get ...
The gun requires constant training, skill, a solid hand. Serdyukov was a good shooter. But not outstanding.

[Pereira]

Here I am about that. AKM has an aiming range of 1000m. Surely there are arrows hitting the target at this distance.

[Glory1974]

What hit range?

My teacher of fire training at the school, shot from the TT at targets for the machine gun, at a range of 250-300 meters and fell.
It all depends on the preparedness of the shooter.

[Free wind]

Recently, it was that they made a bulletproof vest, which is not pierced by any bullet in the world. Now they made a bullet that pierces any body armor.

[Pereira]

In 2014 Ukrainian girl invented a magnetic body armor. Flying up to him, the bullet unfolds sideways. So you need a round bullet.

[svp67]

There will be many rounds of ammunition and samples of weapons under it will begin to appear in a multitude. So the cartridge is good and powerful, to create a compact and powerful PP will be just right

[Sandro1977]

CP 2 aka Heather has long been created under this cartridge

[svp67]

Quote: Sandro1977

CP 2 aka Heather has long been created under this cartridge

I know, but now we should expect the appearance of more new models ...

[garri-lin]

On the basis of such a cartridge, you can make a whole line of weapons. From a compact but powerful pistol. And then PP. Assault software for stripping in cities. 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.

And also for crew members of military vehicles ...

[garri-lin]

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.

[svp67]

Quote: garri-lin

And you can share ammo and the same range.

I think that at the moment when this happens, there will be a lot of infantry weapons lying on the ground.

Quote: garri-lin

I think one cartridge is better on the battlefield.

PP for such a cartridge, yet a more compact weapon and a smaller cartridge allows you to take more ammunition, it would be nice to "pack" it into "auger" under-barrel magazines of large capacity.

[garri-lin]

Maybe you're right. To be honest, I myself have not decided on this issue. Sometimes I contradict myself. Sometimes it seems that conventional weapons are preferable. Sometimes that's compact.

[Ros 56]

God forbid from contact with this miracle.

[soul]

Production seems to be in Klimovsk. I worked there.

[Yrec]

And I, naive, thought that "Tochmash" was preparing for the production of WEAPONS, and ammunition - cartridge factories If the cartridges already have a GRAU index, then they are already READY for production. At "Tochmash", it seems, too, "effective managers" with cosmic salaries have bred with a mess in their heads. I don't think there will be enough money for cartridges.

[Captan78]

Maybe all the same power?

[alex aircraft]

For cartridges (gyurza) and Wed 2 Heather, these cartridges are suitable? Otherwise it was such a reinforced cartridge for mm, but it was forbidden to shoot from pm because of barrel wear and danger of destruction.

[Alexander Drobyshev]

Greetings, the "subsonic" cartridge 7U4 is suitable for sure, there can be no increased pressure, there is no clarity about cartridge 7N42, if it has the same bullet weight and speed, and the penetration is increased due to the shape of the core, then most likely they are suitable, otherwise history will repeat itself with the PMM patron

[yfast]

Why not "increased, increased energy, power", why power?

Dear editors of the site! when will you finally perform your duties? how much can you write any heresy then? or you take an example from the victims of the exam, who edited the publication of ballots for voting on amendments to the Constitution! You know, but reading such headlines is simply embarrassing for your teachers! ENHANCED POWER! Doesn’t hurt your eyes ?!

[czes]

Maximalists, damn it. Make a decent gun under 9 × 19 mm Parabellum and there will be happiness for the people! Yes, by the way, the question is: have 9 × 19 mm been adopted?
