12.7mm VSSK (Vintovka Snayperskaya Spetsialnaya Krupnokalibernaya - special sniper rifle, large caliber) "Vychlop" (Exhaust) silenced sniper rifle is one of the most recent creations of famous Russian Instrument Design Bureau (KBP). Developed in around 2002 on special request from Russian FSB (Federal Security Service, successor of Soviet KGB), this rifle was first show to general public only in late 2005, during arms exhibition INTERPOLITEX 2005 in Moscow. This rifle is said to be in use only by special elements of FSB, which conduct mostly counter-terror and high importance anti-crime operation. Information on this weapon is very scarce, so its description below is based on manufacturer's leaflets that were displayed at the same exhibition. Author plans to extend this article as soon as more reliable and extensive information will be available.

12.7mm "Vychlop" (Exhaust) silenced sniper rifle is developed for special operations that require silent firing and penetration much superior to that provided by 9mm VSS silenced sniper rifle. Typical targets for VSSK Vychlop are cars, terrorists in heavy body armor or behind covers like car bodies or other thick covers. The core of the VSSK complex is specially developed 12.7mm (.50 caliber) reduced power ammunition that launches bullets at subsonic muzzle velocities of about 290 meters per second (~950 fps). Exact dimensions of the new cartridge case are not yet published, but the overall length of the new 12.7mm round designated STs-130PT is given as 97mm, significantly less that of standard Russian 12.7x108 HMG round (145mm overall length). Standard loading for this round is precision machined solid bronze projectile with pointed nose, weighting around 59 gram (910 grains) or 76 gram (1170 grains) "high penetration" bullet. Accuracy is claimed as 1 MOA at 100 meters range with precision bullets, and maximum effective range is given at 600 meters. High penetration bullet can defeat Russian Class 5 (US NIJ Type III / High-Powered Rifle) body armor at 100 meters or 16mm steel plate at 200 meters.

It must be noted that the concept of dedicated.50 caliber silenced weapon with special subsonic ammunition is not new. Back in early 1990s noted American ammunition specialist J.D.Jones of SSK Industries developed a specialized 12.7mm round known as .50 Whisper. This round was based on shortened .460 Weatherby Magnum case, loaded with heavy, pointed low-drag bullet. This cartridge is intended for use in specially modified bolt action rifles (like Winchester Model 70 or Sako TRG-S) fitted with silencers. Ballistic properties of the .50 Whisper are very close to that of 12.7 STs-130 ammunition - both claimed to have accuracy of 1 MOA and decent effectiveness out to 600 meters or so. However, it is not known if any of US law enforcement agencies ever used .50 Whisper or similar guns, while VSSK was developed especially for law enforcement and military special operations use.

VSSK "Vychlop" rifle is fitted with large integral silencer that can be removed for storage, transportation and maintenance. Rifle itself is built using bullpup layout; it has integral folding bipod, and adjustable shoulder pad and cheek rest. Top of the receiver is fitted with scope rail, and rifle is provided with folding back-up iron sights. Apparently, this rifle is semi-automatic, but exact details of the action are unknown. Detachable box magazine holds five rounds of ammunition.

Oh yes.... just what we need.... a silenced .50 cal sniper rifle.

Whats the point? :roll:

[zealot]

^ I agree w/ you to an extent, but than again this is not long range 1km or more anti-material rifle, it's maximum effective range is reported to be 600m, due to it's obvious bull-pup construction and silencer- it is a sniper rifle for clandestine work in a large caliber in built-up urban areas .. when target is behind a window of a car or house for eg..

[Bullet Donor]

Oh yes.... just what we need.... a silenced .50 cal sniper rifle.

Whats the point? :roll:

Why wouldn't you have a suppressor for a .50 cal?

[Alan]

Looks neat, wonder how well it performs. Guess only time will tell.

[henksmoeder]

I am sure the people using those things know why they need them. The FSB is not build around retards.

You're in the business of counter-terrorism yourself or are you just portraying a mighty display of armchair Delta!!11 knowledge?

[Seraphim]

There are some pics of IIRC Canadian snipers on the range with surpressed fiftys.

[turan8]

Isn't the VSS Vintorez already capable of defeating NIJ III armor?

[Flagg]

I'm no ballistics expert but my guess is that anyone even hit in an extremity by one of these heavyweight low velocity rounds:


59 gram (910 grains) or 76 gram (1170 grains)

will no longer be in the fight.......ever

It would be like getting hit by a bus

As well as exploding terrorists like melons, this rifle sounds like it would be quite effective in hunting elephant, Cape Buffalo, or undead zombies.

[fred_engles]

I'm skeptical of the claim of 600m range with a subsonic round, though.

[CyberSpec]

It probably won't be used at that distance in practice, but it doesn't sound impossible...then again I'm no balistics expert either

IIRC, the FSB actually asks internet goers what guns are cool and what ones are t3h suxx0rz. This is how they work, you know. ;)

[GazB]

I'm skeptical of the claim of 600m range with a subsonic round, though.

A very heavy projectile loses velocity more slowly than a lighter projectile. Needless to say that early flat based 30 cal rifle bullets with flat bases instead of boat tailed bases had their ballitic range tripled with the simple addition of boat tails. A modern 308 bullet becomes subsonic at about 800m and travels the rest of its range (up to 3-4km) at subsonic speeds. By increasing the mass of the bullet so that instead of 800m it is subsonic at the muzzle would probably not result in a dramatic reduction in max range as the extra mass would equal extra momentum and reduce the rate at which it lost speed in flight.

[Resurrection]

Wow, you're pretty damn smart.

[TacoDelRio]

Only when he's on crack. ;)

So who here has shot this exact rifle yet? C'mon, don't be shy!

I know, man. Thanks to the counterstrike forum the standard issue sidearm for FSB already is .....

Oh God no, did I say silencer instead of suppressor?!:roll:

And there is nothing wrong with adding a suppressor to a .50 cal rifle, as it reduces the muzzle report making it more comftable to fire for the shooter.

Having a specially made silenced rifle using sub-sonic ammo in .50 though, is daft. It has a very small niche, and you can't issue it in addition to another rifle, who could afford to issue everyone two rifles?

Well thats nothing new when looking into the russian weaponry is it. Its how it works over there.

If you notice the original title it says FSB (ex-KGB) rifle.

So it won't be issued to the regular army -- meaning limited numbers for special purposes.

I sooo want one

them elephants run rampant in your neighbourhood?


it does look neet though

[Jippo]

I would be wary of claims of 600m range with a subsonic 12.7mm round.

KBP claims the OC-14 Groza assault rifle which fires the 9x39mmSP6 round has an effective range of 400m but according to Russian SF troops the heavy 16g bullet begins to arc somewhat after 200m.

A Subsonic 12.7mm round would be meet even more air resistance than the SP6.

The question of air resistance is a function of shape and sectional density, in defeating air resistance heavier bullet wins.

Also arcing is a different matter compared to accuracy, arcing doesn't matter at all if the range can be accurately measured.

What can I say, It's Texas.

[JoaMei]

A tiny shockwave in the front of the bullet hits the target just before the bullet does.

Which generates the biggest shockwave, a light, fast bullet or a slow, heavy one?

IIRC to have a Shockwave the Bullet has to be supersonic, its a question what slow or fast mean to you.

[liberation]

A 7.62x39mm round fired from an AK-47 is bigger and slower than an 5.56x45mm round fired from an M-16.

Which generates a bigger shockwave?

The 5.56mm does, the effect on tissue is really impressive.

[liberation]

Thanks. I assume the faster moving 5.56 is preferable for penetration, the 7.62 for stopping power.

[Kvakva]

actually no, 7.62 has better penetration. 5.56 is less stable than it hits you the wound is much worse compared to 7.62.
Ofcause if they are regular bullets not AP.

[Hollis]

Rainbow projectal have been effective to ranges going out there (checkout Civil War snipers and look at Black powder firearms). Slow bullets, lots of Arcing but with proper range estimation is accurate, BUT range has to be also accurate. Subsonic stuff is also range limited because of retained muzzel energy. A bullet needs to be subsonic, Generally heavy bullets are used, because of loading requirements smaller cases than normal are used. Like a 220 grain bullet in a 7.62 x 39 case (308 case would be dangerous to use). Also the rifles twist has to be matched to the heavier/longer bullet.

A 220 gr HPBT match king at 400 Yards has the retained muzzel energy of 295 Ft Lbs. Velocity at the muzzel was 850 Ft/sec, drop was -409 in. At Super sonic speeds and at 400 yards, 1749 Ft lbs of energy, velocity at muzzel was 2400 fps drop was -29 in. You can see any error in range is a lot of bullet drop for a subsonic load.

A quick example is the 9mm, 147 Grain bullets are used for subsonic loads. With out adding somesort of inert filler to the case, 115 gr bullets can not be used safely. Insuffiecent powder charges in a case can cause excessive chamber pressures.

The other limitation in versitility in range, is: "how much bullet drop a scope can handled over the range the rifle will be used?"

Sighting in for ranges 100 yrd to 400 with the 308 would require a scope to handle over 375 in. in change.

Yeh, doesn't the 5.56 round tend to tumble once it hits the intended target?(if said target is a person)

Wound ballistics diagrams show ****ounced fragmentation, rather than strict yaw.
