The 7.62x39mm Cartridge: The Heart of the AK-47
The AK-47 is primarily chambered for the 7.62x39mm cartridge, also known as the 7.62 Soviet. This intermediate cartridge was developed in the Soviet Union during World War II and became the standard round for the AK-47 and its many variants. Understanding the 7.62x39mm cartridge is crucial to understanding the AK-47’s capabilities and limitations.
Historical Context: The Birth of an Intermediate Cartridge
Prior to World War II, most military rifles used full-power rifle cartridges, such as the .30-06 Springfield in the United States or the 7.92x57mm Mauser in Germany. While these cartridges offered excellent range and stopping power, they were also heavy, produced significant recoil, and were often overkill for the close-quarters combat that characterized much of the war. The Soviets recognized the need for a cartridge that offered a balance between range, power, and controllability. This led to the development of the 7.62x39mm.
Technical Specifications of the 7.62x39mm
The 7.62x39mm cartridge consists of several components:
* **Bullet:** Typically a 123-grain (8 gram) full metal jacket (FMJ) bullet. Other bullet types, such as hollow points and soft points, are also available for hunting or defensive purposes.
* **Case:** A bottlenecked case made of steel or brass. Steel cases are more common in military ammunition due to their lower cost and availability.
* **Primer:** A small explosive charge that ignites the propellant.
* **Propellant:** The gunpowder that burns rapidly to generate the gas pressure that propels the bullet down the barrel.
The dimensions of the cartridge are as follows:
* **Bullet Diameter:** 7.62mm (.30 caliber)
* **Case Length:** 39mm
* **Overall Length:** 56mm
Typical performance characteristics include a muzzle velocity of around 2,330 feet per second (710 meters per second) and a muzzle energy of around 1,500 foot-pounds (2,034 joules).
Variations and Manufacturers of 7.62x39mm Ammunition
The 7.62x39mm cartridge is manufactured by numerous companies around the world, including:
* **Russian manufacturers:** Wolf, Tula, Barnaul

* **American manufacturers:** Hornady, Federal, Winchester
Ammunition varies in quality, bullet type, and case material. Some manufacturers offer specialized loads, such as tracer rounds (which leave a visible trail) or armor-piercing rounds.
The AK-47 and the 7.62x39mm: A Symbiotic Relationship
The AK-47 was designed specifically around the 7.62x39mm cartridge. The rifle’s operating system, barrel length, and overall design are optimized for this round. The combination of the rifle and the cartridge proved to be a winning formula, offering a balance of firepower, controllability, and reliability that was unmatched by other firearms of the time.
Ballistics and Effective Range of the AK-47
The 7.62x39mm cartridge gives the AK-47 an effective range of approximately 300-400 meters. While not as accurate or long-ranged as rifles chambered for full-power cartridges, the AK-47 is more than adequate for most combat scenarios. The cartridge’s relatively flat trajectory out to 200 meters makes it easy to aim, and its moderate recoil allows for rapid follow-up shots.
Stopping Power and Terminal Ballistics
The 7.62x39mm cartridge is known for its good stopping power, meaning its ability to quickly incapacitate a target. The 123-grain bullet delivers significant energy upon impact, causing considerable tissue damage. While not as devastating as larger calibers, the 7.62x39mm is generally considered to be more effective than smaller, high-velocity rounds like the 5.56x45mm NATO (used in the AR-15).
Terminal ballistics, the study of how a bullet behaves upon impact with a target, is complex. Factors such as bullet design, velocity, and the type of tissue struck all influence the outcome. In general, the 7.62x39mm bullet tends to tumble and fragment upon impact, increasing its effectiveness.
Beyond the 7.62x39mm: Other Calibers in AK-Pattern Rifles
While the AK-47 is most commonly associated with the 7.62x39mm cartridge, AK-pattern rifles have been produced in other calibers as well. These variations were often developed to meet the specific needs of different military forces or to appeal to civilian markets.
The 5.45x39mm Cartridge
In the 1970s, the Soviet Union introduced the 5.45x39mm cartridge as a replacement for the 7.62x39mm. This smaller, lighter cartridge offered several advantages, including flatter trajectory, reduced recoil, and increased magazine capacity. The AK-74, the successor to the AK-47, was designed to chamber this round.
The 5.45x39mm bullet typically weighs around 53 grains (3.4 grams) and has a muzzle velocity of around 2,950 feet per second (900 meters per second). While it has less stopping power than the 7.62x39mm, its higher velocity and flatter trajectory make it more accurate at longer ranges.
Other Less Common AK Calibers
* **5.56x45mm NATO:** Some AK-pattern rifles have been produced in the 5.56x45mm NATO caliber, primarily for export to countries that use this standard NATO round.
* **.223 Remington:** Similar to 5.56x45mm, this is a popular civilian cartridge that some AK variants have been chambered for.
* **Shotgun Calibers:** Certain AK-derived platforms, like the Saiga-12, are chambered for 12-gauge shotgun shells, offering a completely different role as a combat shotgun.
