Russian Tekhkrim’s Duplex 7.62x54 Ammunition

Tekhkrim, a Russian firearms and ammunition manufacturer, has announced the start of serial production for new 7.62x54 cartridges. While this concept is not new, it has been revisited throughout history for various purposes. As the battlefield evolves, new solutions are needed to address emerging threats. While not explicitly stating that this is to counter drones, the description, design, and short range imply that this duplex ammunition has been developed to counter fast-moving drones. These cartridges are designed for use in any small arms chambered for the 7.62x54 caliber, aiming to increase projectile density at distances of up to 350 meters.

The design is highly likely intended for counter-unmanned Aircraft Systems (C-UAS) and is effective at ranges of up to 350 meters. Using two lighter-weight projectiles with lower muzzle velocities will lead to decreased terminal ballistics, but it will increase hit probability.

Russian systems that have been used for C-UAS include the PKT machine gun, which can fire up to 800 rounds per minute. Recently, another option has emerged: the GShG-7.62 minigun, which can fire up to 6,000 rounds per minute. For infantry applications, standard PKM/PKP general-purpose machine guns can be employed for both traditional and C-UAS use. Adjusting the gas setting to position three will help increase the fire rate, enhance overall fire volume, and improve hit probability.

If it hasn't already, the new cartridge will likely be tested in the Russo-Ukrainian War for C-UAS. However, no information is currently available regarding whether it has already been tested or fielded. I previously wrote an article about a recent Russian patent for the duplex 7.62x54 cartridge here.
