What if I instructed you that you would suppress a firearm with out the necessity for a suppressor? You possibly can really muffle the sound of a gunshot through the use of a particular ammunition design. You might be primarily silencing the gun with the ammunition itself. How precisely does silent ammo work? Did anybody really use it? Is it efficient? At this time we’ll reply all these questions and extra.
How Does Silent Ammo Work?
Silent ammo is so easy and engaging that it’s spectacular it isn’t extra widespread. If the NFA didn’t exist, I guess we’d see these cartridges flourish for numerous searching functions. The thought is straightforward: it’s essential to create a seal between the burning propellant and the projectile. There have been just a few methods to perform this.
The most typical technique locations a captive piston between the propellant and the projectile. When the primer ignites the cartridge, it drives the captive piston ahead. The piston strikes the projectile and propels it down the barrel. Nonetheless, the piston is designed to jam or “seat” on the neck of the cartridge case, performing as a fuel seal that stops the explosion of fuel from ever leaving the casing. For the reason that fuel is trapped, there is no such thing as a muzzle blast and, subsequently, little or no noise.

An alternative choice is a gas-sealed actuator. In some examples, the cartridge makes use of what is basically a specialised steel diaphragm or aluminum foil. When the spherical is fired, the powder cost fills this diaphragm with fuel, nearly like a balloon, which then presses on the projectile and propels it ahead. It’s a very comparable idea to the captive piston, simply utilizing a versatile actuator as a substitute of a strong piston.
Whereas there’s seemingly a 3rd technique utilized in an obscure prototype someplace, these two stay the first methods to attain “internally suppressed” ammunition. The captive piston is by far the most well-liked and profitable of the 2.

Who Used Silent Ammo?
The 2 important customers of silent ammunition have been the US and Russia. Unsurprisingly, the Russians made probably the most in depth use of the know-how, whereas China has utilized it in a extra restricted capability. America experimented with the idea through the Vietnam Struggle however rapidly moved on to extra conventional suppression strategies.
The Russians are the true sticklers for silent ammunition, producing quite a few firearms particularly chambered for these oddball cartridges. Whereas the Chinese language made a silent dart gun for making use of tranquilizers, we’ll concentrate on the deadly designs. The US briefly explored silent rifle, pistol, and shotgun rounds, however by no means adopted them on a big scale.
The Russian Choice
The Russians have been large on this development. Maybe the clandestine nature of Soviet-era particular operations made them desire a quieter, much less cumbersome choice than a typical suppressed pistol. They caught to the captive piston design for his or her silent ammo sorts.

One of many first was the S4M, a extremely secretive double-barrel derringer that fired 7.62 projectiles. This pistol was designed to fireside a cartridge that would go away investigators satisfied an AK-47 had been used from a distance, relatively than a point-blank assassination weapon.
The S4M led to the MSP Groza silent pistol, one other derringer design that fired a much less highly effective 7.62 cartridge with a a lot shorter case. These two double-barrel pistols finally gave method to a semi-auto design referred to as the PSS. This gun fired the SP4 cartridge and held six rounds. It used a novel design with a hard and fast barrel however a floating chamber to help in biking the motion.

They even reverted again to revolvers with the OTs-38, which makes use of the identical SP4 cartridge with a moon clip. The revolver presents an easier, extra dependable mechanical choice than the sophisticated semi-auto PSS.
The American Choices
The blessings of American innovation allowed the US to check a number of silent cartridges. Essentially the most distinguished was the QSPR (Quiet Particular Objective Revolver). A product of the AAI Company, it was made particularly for Tunnel Rats in Vietnam. This was a Smith & Wesson Mannequin 29 .44 Magnum revolver with the barrel trimmed to lower than an inch.
The gun used captive piston ammo however was loaded with shot pellets. The cartridges resembled quick .410 shells, every holding 15 tungsten-alloy pellets produced from a fabric referred to as Mallory. This tungsten alloy maximized density and close-range vitality. The efficient vary was about 30 ft. An after-action report from an Military Ranger patrol mentions utilizing the QSPR to kill an enemy combatant throughout a patrol.

Past that, AAI produced a silent 12-gauge cartridge. This shell used a steel diaphragm fuel actuator to propel 12 rounds of No. 4 buckshot from a typical pump-action shotgun. The cartridge was solely steel. In response to historian Kevin Dockery, the shell was not fully silent, nevertheless it made the weapon very laborious to listen to and successfully unnoticeable in a fight atmosphere.

AAI additionally developed the DBCATA system, which used comparable know-how to launch silent 40mm grenades. Info on this technique is proscribed, nevertheless it was apparently extraordinarily costly to provide and was finally scrapped.
Silent Ammo At this time
The Russians appear to be the one folks nonetheless fielding these weapons. Like many Russian designs, they pop up in conflicts all over the world, together with Ukraine and Syria. Past that, there isn’t a lot trendy experimentation with the idea. The vary is severely restricted, and the firearms required to cycle these rounds reliably are troublesome to engineer.
At this time, suppressors are cheaper, more practical, and simpler to discipline than a specialised gun with proprietary ammo. Whereas the idea is attention-grabbing, it has only a few trendy army functions. Moreover, because of the NFA, every particular person cartridge would seemingly be legally labeled as a “suppressor,” making the price and paperwork a nightmare for civilians. Nonetheless, it stays a captivating subcategory of ammunition that by no means fairly received its time within the solar.
