What Bullet Does an AK-47 Rifle Use? Understanding the 7.62x39mm Cartridge

The AK-47, an iconic and widely recognized assault rifle, is known for its reliability, simplicity, and effectiveness in various combat scenarios. A crucial aspect of its performance lies in the ammunition it utilizes. So, what bullet does an AK-47 rifle actually use? The answer is the 7.62x39mm cartridge, a round specifically designed for the AK-47 and its variants. This article delves into the specifics of the 7.62x39mm cartridge, exploring its characteristics, history, performance, and impact on the AK-47’s overall effectiveness.

The 7.62x39mm Cartridge: An Overview

The 7.62x39mm cartridge is a rimless bottlenecked intermediate rifle cartridge developed in the Soviet Union during World War II. It was designed to bridge the gap between pistol cartridges and full-power rifle cartridges, offering a balance of manageable recoil and sufficient stopping power. The development of this cartridge was closely tied to the development of the AK-47 itself, as the two were conceived as a system to equip Soviet soldiers with a modern and effective firearm.

Key Characteristics

Caliber: 7.62mm (approximately .30 caliber)
Bullet Weight: Typically ranges from 122 to 125 grains
Muzzle Velocity: Around 2,330 feet per second (710 meters per second)
Muzzle Energy: Approximately 1,540 foot-pounds (2,090 joules)
Case Type: Rimless, bottlenecked

History and Development

The 7.62x39mm cartridge was developed in response to the experiences of Soviet soldiers during World War II. They observed that existing rifle cartridges were often too powerful for close-quarters combat, while submachine guns lacked the range and accuracy needed for longer-distance engagements. The 7.62x39mm was intended to provide a compromise, offering a cartridge that was effective at both close and medium ranges. The cartridge was designed by a team led by Nikolai Elizarov and Boris Semin, and it was officially adopted by the Soviet military in 1949, along with the AK-47 rifle.

The AK-47 and the 7.62x39mm: A Perfect Match

The AK-47 was specifically designed to utilize the 7.62x39mm cartridge. The combination of the rifle’s design and the cartridge’s characteristics resulted in a firearm that was reliable, easy to use, and effective in a variety of combat situations. The 7.62x39mm provides a good balance of power and control, making the AK-47 manageable even in full-automatic fire. The cartridge’s relatively low recoil also contributes to the rifle’s accuracy, especially in rapid-fire scenarios.

Advantages of the 7.62x39mm in the AK-47

Stopping Power: The 7.62x39mm delivers significant energy on impact, making it effective at incapacitating targets.
Penetration: The cartridge has good penetration capabilities, allowing it to defeat light cover and barriers.
Reliability: The 7.62x39mm is known for its reliable feeding and extraction in the AK-47, even under harsh conditions.
Availability: Due to the AK-47’s widespread use, the 7.62x39mm cartridge is readily available in many parts of the world.

Performance and Ballistics

The 7.62x39mm cartridge exhibits consistent performance at typical combat ranges. Its ballistic characteristics make it suitable for engagements out to approximately 300 meters. Beyond this range, the bullet’s trajectory begins to drop significantly, and its energy decreases. However, within its effective range, the 7.62x39mm is a formidable cartridge. The what bullet does an AK-47 rifle question often leads to discussions about its ballistics. While not as flat-shooting as some modern cartridges, its terminal ballistics are well-regarded.

Ballistic Data (Approximate)

Muzzle Velocity: 2,330 fps (710 m/s)
Velocity at 100 meters: 2,100 fps (640 m/s)
Velocity at 300 meters: 1,700 fps (520 m/s)
Energy at Muzzle: 1,540 ft-lbs (2,090 J)
Energy at 100 meters: 1,200 ft-lbs (1,630 J)
Energy at 300 meters: 700 ft-lbs (950 J)

Variants and Ammunition Types

While the standard 7.62x39mm is most commonly associated with the AK-47, there are various types of ammunition available. These include different bullet weights, jacket materials, and core compositions. Some common types include:

Full Metal Jacket (FMJ): The most common type, offering good penetration and reliable feeding.
Hollow Point (HP): Designed to expand upon impact, increasing stopping power but potentially reducing penetration.
Soft Point (SP): Similar to hollow points, but with a softer lead tip for controlled expansion.
Tracer Rounds: Contain a pyrotechnic compound that ignites upon firing, allowing the shooter to visually track the bullet’s trajectory.
Armor-Piercing (AP): Designed to penetrate armored targets, such as body armor or light vehicles.

The Global Impact of the 7.62x39mm

The 7.62x39mm cartridge, largely due to its association with the AK-47, has had a significant global impact. The AK-47’s widespread adoption by military forces, insurgent groups, and civilian users has made the 7.62x39mm one of the most commonly used rifle cartridges in the world. Its availability and relatively low cost have contributed to its popularity, particularly in regions with limited access to more modern ammunition types. Understanding what bullet does an AK-47 rifle fire is key to understanding its prevalence in global conflicts.

Comparing the 7.62x39mm to Other Cartridges

The 7.62x39mm is often compared to other intermediate rifle cartridges, such as the 5.56x45mm NATO and the 5.45x39mm. Each cartridge has its own strengths and weaknesses, and the choice of which one to use depends on the specific requirements of the mission. [See also: 5.56 vs 7.62: A Ballistic Comparison] The 5.56x45mm is generally considered to have a flatter trajectory and lower recoil, while the 7.62x39mm offers greater stopping power and penetration at shorter ranges. The 5.45x39mm, a Soviet cartridge designed to replace the 7.62x39mm, offers a flatter trajectory and reduced recoil compared to its predecessor.

Key Comparisons
