Understanding the 7.62x39mm Cartridge: The Heart of the AK-47
The AK-47 primarily fires the 7.62x39mm cartridge, also known as the 7.62 Soviet round. This intermediate cartridge was developed by the Soviet Union during World War II and became the standard ammunition for the AK-47 and its variants. The designation “7.62x39mm” refers to the bullet’s diameter (7.62mm) and the case length (39mm).
Historical Context and Development
The 7.62x39mm round was designed as a compromise between the longer, more powerful rifle cartridges of the time (like the 7.62x54mmR) and the less powerful pistol cartridges. The goal was to create a round that offered sufficient stopping power at medium ranges while remaining controllable in fully automatic fire. Its development was heavily influenced by the German 7.92x33mm Kurz cartridge, used in the StG 44 assault rifle.
Technical Specifications of the 7.62x39mm Round
* **Bullet Diameter:** 7.62mm (.30 caliber)
* **Case Length:** 39mm
* **Rim Diameter:** 11.35mm
* **Overall Length:** 56mm
* **Typical Bullet Weight:** 123 grains (8 grams)
* **Muzzle Velocity:** Approximately 2,330 feet per second (710 meters per second)
* **Muzzle Energy:** Approximately 1,550 foot-pounds (2,100 joules)
The 7.62x39mm cartridge typically uses a full metal jacket (FMJ) bullet, which consists of a lead core encased in a copper or steel jacket. FMJ bullets are designed to penetrate targets effectively and are less prone to deformation than soft-point or hollow-point bullets. However, variations exist, including hollow point and soft point projectiles that are commonly used for hunting or self defense.
Variations and Manufacturers of 7.62x39mm Ammunition
The 7.62x39mm round is manufactured by numerous companies worldwide. Variations exist in bullet weight, powder charge, and bullet design. Some common manufacturers include:
* **Russian:** Tula, Barnaul, Ulyanovsk
* **Chinese:** Norinco
* **Eastern European:** Various manufacturers in countries like Bulgaria, Romania, and Poland
* **American:** Winchester, Federal, Hornady
These variations can affect the round’s performance in terms of accuracy, velocity, and terminal ballistics. It’s important to choose ammunition that is appropriate for the intended purpose and firearm.
The Role of the 7.62x39mm in the AK-47’s Design
The AK-47 was specifically designed around the 7.62x39mm cartridge. The rifle’s gas-operated system, bolt design, and magazine capacity are all optimized for this round. The intermediate power of the 7.62x39mm allows for a relatively compact and lightweight rifle that is still effective at medium ranges. The AK-47’s design allows for reliable operation even with lower quality ammunition, which contributed to its widespread use.
AK-47 Magazine Capacity and Ammunition
The standard AK-47 magazine holds 30 rounds of 7.62x39mm ammunition. This high capacity allows for sustained fire and makes the AK-47 a formidable weapon in close-quarters combat. Other magazine capacities are available, including 10-round, 20-round, 40-round, and even drum magazines holding up to 75 or 100 rounds.
The Gas-Operated System and Ammunition
The AK-47 utilizes a long-stroke gas-operated system. This system uses the gases produced by the burning gunpowder to cycle the action of the rifle. The 7.62x39mm cartridge provides ample gas pressure to reliably cycle the action, even under adverse conditions.
Performance and Ballistics of the 7.62x39mm Round
The 7.62x39mm round offers a good balance of power, accuracy, and controllability. While it is not as accurate or flat-shooting as some other rifle cartridges, it provides sufficient stopping power for most applications at ranges up to 300 meters. In our experience, the round performs reliably in a variety of conditions.
Effective Range and Accuracy
The effective range of the AK-47 with 7.62x39mm ammunition is generally considered to be around 300 meters. Beyond this range, accuracy decreases significantly due to bullet drop and wind drift. However, at closer ranges, the 7.62x39mm round is capable of delivering accurate and effective fire.
Terminal Ballistics and Stopping Power
The terminal ballistics of the 7.62x39mm round are generally considered to be good. The round’s relatively large bullet diameter and moderate velocity provide significant stopping power. However, FMJ bullets tend to over-penetrate, which can reduce their effectiveness in some situations. Hollow-point and soft-point projectiles offer improved stopping power due to their expansion upon impact.
The Impact and Legacy of the 7.62x39mm Cartridge
The 7.62x39mm cartridge has had a significant impact on military and civilian firearms. Its widespread use in the AK-47 and other rifles has made it one of the most common rifle cartridges in the world. Its availability and relatively low cost have also contributed to its popularity.
Military Use and Proliferation
The 7.62x39mm round has been used by countless military forces and insurgent groups around the world. The AK-47’s simplicity, reliability, and the ready availability of 7.62x39mm ammunition have made it a popular choice for both conventional and unconventional warfare.
Civilian Use and Applications
The 7.62x39mm round is also popular among civilian shooters for hunting, target shooting, and self-defense. Rifles chambered in 7.62x39mm are often less expensive than those chambered in other rifle cartridges, making them an attractive option for budget-conscious shooters. The availability of different bullet types also allows for a variety of applications.
Modern Day Alternatives to 7.62x39mm
