The Heart of the AK-47: The 7.62x39mm Cartridge
The AK-47, a globally recognized assault rifle, is primarily chambered for the 7.62x39mm cartridge. This intermediate cartridge was designed in the Soviet Union during World War II and has since become one of the most widely used military cartridges in the world. Let’s break down what makes this round so significant.
Origins and Development
The 7.62x39mm round was developed in response to the need for a cartridge that offered a better balance between the power of a full-size rifle cartridge (like the 7.62x54mmR) and the controllability of a pistol cartridge. The Soviet military observed the effectiveness of German assault rifles using intermediate cartridges and sought to create their own. The result was the 7.62x39mm, which proved to be highly effective in the AK-47.
Technical Specifications
* **Bullet Diameter:** 7.62mm (.30 caliber)
* **Case Length:** 39mm
* **Overall Length:** 56mm
* **Bullet Weight:** Typically ranges from 122 to 125 grains (8 grams)
* **Muzzle Velocity:** Approximately 2,330 feet per second (710 meters per second)
* **Muzzle Energy:** Around 1,500 foot-pounds (2,034 joules)
These specifications demonstrate the cartridge’s ability to deliver significant energy downrange while remaining manageable in a select-fire rifle.
Design and Functionality
The 7.62x39mm cartridge typically features a full metal jacketed (FMJ) bullet, which provides good penetration and reliability. The cartridge case is usually made of steel, although copper-washed steel and brass cases are also used. The bullet’s shape is designed for aerodynamic stability, ensuring accuracy at typical combat ranges. The tapered case design aids in reliable feeding and extraction in the AK-47’s action.
Understanding the Ballistics and Performance of the 7.62x39mm
The ballistics of the 7.62x39mm round are a critical aspect of its effectiveness. Here’s a closer look at its performance characteristics.
Effective Range
The effective range of the 7.62x39mm cartridge in the AK-47 is generally considered to be around 300-400 meters. Beyond this range, the bullet’s trajectory becomes less predictable, and its energy decreases significantly. However, at closer ranges, the 7.62x39mm delivers substantial stopping power.
Penetration Capabilities
The 7.62x39mm round is known for its good penetration capabilities, especially when using FMJ bullets. It can penetrate light cover, such as wood, drywall, and some types of body armor. However, modern body armor is designed to defeat this round, highlighting the ongoing arms race between ammunition and protective gear.
Stopping Power
While the 7.62x39mm doesn’t have the same raw power as larger rifle cartridges, it offers excellent stopping power at close to medium ranges. The bullet’s size and velocity transfer a significant amount of energy upon impact, which can quickly incapacitate a target. This stopping power has contributed to the AK-47’s reputation as a formidable weapon.
The AK-47 and 7.62x39mm: A Symbiotic Relationship
The AK-47 and the 7.62x39mm cartridge are intrinsically linked. The rifle was specifically designed to maximize the potential of this round, and their combination has proven incredibly successful on battlefields around the world.
Reliability in Harsh Conditions
One of the key reasons for the AK-47’s widespread adoption is its legendary reliability. The 7.62x39mm cartridge plays a role in this reliability, as its tapered case design and robust construction contribute to smooth feeding and extraction, even in dirty or adverse conditions. According to anecdotal reports from soldiers, the AK-47 can function reliably even with minimal maintenance, a testament to its design and the cartridge it uses.
Ease of Production
The 7.62x39mm cartridge is relatively simple and inexpensive to manufacture, which has made it accessible to a wide range of countries and organizations. This ease of production has contributed to its global proliferation and the AK-47’s status as one of the most common firearms in the world.
Versatility
While the AK-47 is primarily an assault rifle, the 7.62x39mm cartridge is also used in a variety of other firearms, including carbines, light machine guns, and even some pistols. This versatility further underscores the cartridge’s importance and adaptability.
Variations and Alternative Ammunition for the AK-47
While the 7.62x39mm is the primary cartridge for the AK-47, some variations and alternative ammunition options exist.
Steel Core Ammunition
Steel core ammunition features a steel penetrator inside the bullet, which enhances its ability to pierce through hard targets. This type of ammunition is often used in military applications where improved penetration is required.
Tracer Ammunition
Tracer ammunition contains a pyrotechnic compound that ignites when the bullet is fired, creating a visible trail in the air. This allows soldiers to visually track their shots and make corrections as needed. Tracer rounds are often mixed with standard ammunition in magazines to provide guidance for aiming.
Armor-Piercing Ammunition
Armor-piercing (AP) ammunition is designed to penetrate body armor and other protective materials. These rounds typically feature a hardened steel or tungsten core and are often used in specialized military applications. However, the legality of AP ammunition varies depending on the jurisdiction.
Soft Point Ammunition
Soft point ammunition features a bullet with an exposed lead tip, which expands upon impact, creating a larger wound cavity. This type of ammunition is often used for hunting and self-defense, as it delivers more stopping power than FMJ rounds. However, soft point ammunition may not be legal in all areas.
The 7.62x39mm in Modern Conflict and Civilian Use
The 7.62x39mm cartridge continues to be used in conflicts around the world, as well as in civilian shooting sports and hunting.

Hunting
While not ideal for all types of game, the 7.62x39mm can be used for hunting medium-sized animals like deer and wild boar. Soft point ammunition is typically preferred for hunting, as it delivers better stopping power than FMJ rounds. However, hunters should be aware of local regulations and ensure that the cartridge is appropriate for the game they are pursuing.
