The AK-47, designed by Mikhail Kalashnikov, is famed for its ruggedness and simplicity. However, the effectiveness of any firearm relies heavily on its ammunition. The 7.62x39mm cartridge, the standard “ak 47 ammo size,” is a key component of this weapon’s success. Let’s explore the nuances of this cartridge.
## Understanding the 7.62x39mm Cartridge: The AK-47 Ammo Size
The term “ak 47 ammo size” refers to the 7.62x39mm cartridge, a bottlenecked intermediate rifle cartridge developed in the Soviet Union during World War II. This cartridge is the standard ammunition for the AK-47 and many other rifles derived from or inspired by its design. Understanding its dimensions and characteristics is crucial for anyone involved with or interested in the AK-47 platform.
### Core Components and Dimensions
The 7.62x39mm cartridge consists of several key components:
* **Bullet:** Typically a full metal jacket (FMJ) projectile, although other types like hollow points and soft points are available for hunting or defensive purposes. The bullet diameter is approximately 7.92 mm (.312 inches).
* **Case:** A bottlenecked brass or steel case that holds the primer, powder, and bullet. The case length is 38.6 mm (1.52 inches).
* **Primer:** A small explosive charge located at the base of the case that ignites the powder when struck by the firing pin.
* **Powder:** The propellant that generates the gas pressure to propel the bullet down the barrel.
The overall length of the cartridge is approximately 56 mm (2.20 inches). These dimensions are critical for proper feeding and function within the AK-47’s action.
### History and Development
The 7.62x39mm cartridge was developed in the Soviet Union during World War II as a response to the German 7.92x33mm Kurz cartridge used in the StG 44 assault rifle. The Soviets recognized the need for an intermediate cartridge that offered a balance between the power of a full-size rifle cartridge and the controllability of a pistol cartridge. This led to the creation of the 7.62x39mm, which was subsequently adopted as the standard ammunition for the AK-47 and its derivatives.
### Ballistic Performance
The 7.62x39mm cartridge delivers a muzzle velocity of approximately 710-735 m/s (2,330-2,410 ft/s) with a typical 123-grain bullet. This results in a muzzle energy of around 2,000 joules (1,500 ft⋅lbf). While not as powerful as larger rifle cartridges like the 7.62x51mm NATO, the 7.62x39mm offers a good balance of power, accuracy, and controllability, making it effective for close to medium-range engagements.
### Variations and Types
Several variations of the 7.62x39mm cartridge exist, each designed for specific purposes:
* **FMJ (Full Metal Jacket):** The most common type, used for general-purpose shooting and military applications. Offers good penetration.
* **Hollow Point:** Designed for hunting and self-defense, these bullets expand upon impact, creating a larger wound cavity.
* **Soft Point:** Similar to hollow points, but with a softer lead tip that expands upon impact.
* **Tracer Rounds:** Contain a pyrotechnic compound that ignites upon firing, allowing the shooter to visually track the bullet’s trajectory.
* **Armor-Piercing Rounds:** Designed to penetrate armor and hard targets. These rounds often have a hardened steel core.
### Importance and Current Relevance
The 7.62x39mm cartridge remains highly relevant today due to the widespread use of the AK-47 and its derivatives around the world. It’s a popular choice for recreational shooting, hunting, and self-defense. Its affordability and availability also contribute to its continued popularity. Recent trends show a resurgence in interest in the AK platform, further solidifying the 7.62x39mm’s position in the ammunition market.
