Unlike the Russians though, the Chinese actually fielded it with their Type 64 and later Type 85 silenced submachine guns. I'll also mention the Chinese People's Liberation Army fields a similar cartridge, called the Type 64, which is very similar to this Russian design. They eventually developed and adopted the 9x39mm to replace the subsonic 200-grain 7.62x39mm ammunition then in service. While this loading proved both very quiet and accurate, it lacked the terminal performance and penetration the Russians were looking for from their next generation of subsonic ammunition. Plus, this projectile was designed with an early yaw cycle, to improve terminal performance. Plus, QC on it was held to a higher standard, due to it being intended for sniper use. The chosen projectile is of suitable weight and length for the small pistol cartridge, and was readily available. The case was also well designed for use in automatic weapons, production machinery was readily available and the Soviets were very familiar with producing it.
This actually made a lot of sense as the smaller case capacity of the 7.62x25mm cartridge was beneficial in a subsonic cartridge. One combination they tried was loading the 7.62x25mm M1930 “Tokarev” cartridge case using the 152-grain bullet from 7.62x54mmR 7N1 “Sniper” ammunition.
Their goal was to develop a quiet but accurate subsonic load with sufficient penetration and terminal performance for effective use in combat. This was during development work focused on replacing the subsonic 7.62x39mm ammunition fielded by Spetsnaz and Scout units. One interesting tidbit many do not know is that while developing/testing subsonic ammunition prior to the adoption of the 9x39mm cartridge, Russian engineers dabbled with the 7.62x25mm. Subsonic bullets maintain velocity very well. These bullets expand at velocities from 1050fps (Max application velocity) down to 750fps (500m+ distance). Looking for something else?

This patented ground breaking monolithic expanding copper bullet (Subsonic) is designed for all types of stealth hunting where very little noise is desired. We carry only the brands you trust such as Fiocchi, Brown Bear, and Remington. Because of these reasons, it’s easy to see why shooters are flocking to subsonic ammunition.īrowse K-Var’s selection of subsonic ammunition today. The reduced muzzle flip also adds accuracy, by keeping the target in the field of view of the scope for faster follow up shots. Subsonic ammo drastically reduces the recoil and virtually eliminates any flinch, resulting in a significantly increased level of accuracy. Suppressors, when used with subsonic ammo, make the sport of shooting much safer and more pleasant. While suppressors were historically used mostly by members of the military or law enforcement, they’ve gained popularity over the years thanks to the safety aspect of the more muted shots. When paired with a suppressor, the rounds become even quieter - a major benefit for those looking to be covert. Subsonic ammunition leaves the barrel moving slower than the speed of sound. Likewise, subsonic ammunition is quickly becoming a favorite of target shooters and plinkers due to the reduced sonic signature, protecting the hearing of shooters and spectators. However, hunters also utilize subsonic ammo as it can reduce or eliminate the deafening, animal-scattering sound of a gunshot. This stealth style of ammo is most often used by military or law enforcement. Subsonic ammunition is specifically designed not break the sound barrier and commonly used in suppressed weapons. Sub-X® (Subsonic eXpanding) bullets deliver big results without a big bang Designed to provide deep penetration below the speed of sound, Sub-X® features a lead core.
