Decoding the AK-47: Understanding What Ammo It Uses
The AK-47, an iconic assault rifle recognized worldwide, is famed for its reliability, simplicity, and widespread use. A crucial aspect of understanding this firearm is knowing what ammo does AK47 use. This article delves into the specifics of the ammunition used by the AK-47, its variations, and its impact on the rifle’s performance and application. We’ll explore the history, technical details, and practical considerations surrounding the AK-47’s ammunition, providing a comprehensive overview for enthusiasts, professionals, and anyone interested in the mechanics of this legendary weapon.
The Primary Ammunition: 7.62x39mm
The most common and original ammunition for the AK-47 is the 7.62x39mm cartridge. This intermediate cartridge was developed by the Soviet Union during World War II and became the standard round for the AK-47 when it was adopted in 1949. The 7.62x39mm round is known for its balance of power, range, and controllability, making it suitable for a variety of combat situations. What ammo does AK47 use often comes down to this standard round.
Characteristics of the 7.62x39mm Round
- Bullet Diameter: Typically 7.92 mm (0.312 inches)
- Case Length: 39 mm
- Bullet Weight: Ranges from 122 to 125 grains (approximately 8 grams)
- Muzzle Velocity: Around 2,330 feet per second (710 meters per second)
- Muzzle Energy: Approximately 1,550 foot-pounds (2,100 joules)
The 7.62x39mm round provides significant stopping power at short to medium ranges, making it effective in close-quarters combat. Its relatively heavy bullet retains energy well, offering reliable performance even when encountering obstacles like light cover. However, its trajectory drops more significantly at longer ranges compared to smaller, higher-velocity rounds.
AK-47 Variants and Their Ammunition
While the 7.62x39mm is the primary cartridge for the original AK-47 and many of its variants, various modifications and adaptations of the AK platform have been chambered in different calibers. These changes were often driven by military or market demands for different performance characteristics or logistical considerations. Understanding what ammo does AK47 use in these variants requires a closer look.
5.45x39mm: The AK-74 and Its Ammunition
The AK-74, introduced in the 1970s, represents a significant evolution of the AK platform. It utilizes the 5.45x39mm cartridge, a smaller, lighter, and higher-velocity round compared to the 7.62x39mm. This change was intended to improve accuracy, reduce recoil, and increase the effective range of the rifle.
- Bullet Diameter: Typically 5.60 mm (0.220 inches)
- Case Length: 39 mm
- Bullet Weight: Ranges from 53 to 60 grains (approximately 3.4 to 3.9 grams)
- Muzzle Velocity: Around 2,950 feet per second (900 meters per second)
- Muzzle Energy: Approximately 1,030 foot-pounds (1,400 joules)
The 5.45x39mm round offers a flatter trajectory and reduced recoil, making it easier to control during rapid fire. While its stopping power is generally considered less than the 7.62x39mm at very close ranges, its improved accuracy and effective range have made it a popular choice for modern military applications. It’s important to know that when considering what ammo does AK47 use, in the AK-74, it’s the 5.45x39mm.
5.56x45mm NATO: Export and Modernized AKs
In response to the widespread adoption of the 5.56x45mm NATO cartridge by Western militaries, some AK variants have been chambered in this caliber. This allows for interoperability with NATO forces and access to a wider range of ammunition types. Several manufacturers, particularly those producing AKs for export, have adapted the design to accommodate this round.
- Bullet Diameter: Typically 5.70 mm (0.224 inches)
- Case Length: 45 mm
- Bullet Weight: Ranges from 55 to 77 grains (approximately 3.6 to 5.0 grams)
- Muzzle Velocity: Varies widely depending on the specific load, but typically around 3,100 feet per second (945 meters per second)
- Muzzle Energy: Varies widely, but typically around 1,300 foot-pounds (1,760 joules)
The 5.56x45mm NATO round is known for its high velocity and relatively flat trajectory. It is effective at longer ranges and offers good accuracy. However, its stopping power is a subject of debate, with some arguing that it is less effective than the 7.62x39mm at very close ranges. Knowing what ammo does AK47 use when it’s chambered in 5.56x45mm is crucial for proper functionality.
Other Calibers: Less Common AK Variants
Besides the three main calibers, some less common AK variants have been produced in other calibers, often for specific markets or purposes. These include:
- .223 Remington: Similar to 5.56x45mm NATO, often used in civilian markets.
- 7.62x51mm NATO (.308 Winchester): Used in some designated marksman rifles based on the AK platform.
- 9x19mm Parabellum: Used in some submachine gun variants of the AK.
These variants are relatively rare compared to the AKs chambered in 7.62x39mm, 5.45x39mm, and 5.56x45mm NATO. When considering the question of what ammo does AK47 use, these niche calibers are typically not what comes to mind, but they exist.
Ammunition Types and Their Effects
Within each caliber, there are various types of ammunition designed for different purposes. These include:
- Full Metal Jacket (FMJ): The most common type, designed for general-purpose use.
- Hollow Point (HP): Designed to expand upon impact, increasing stopping power (often restricted in military use).
- Soft Point (SP): Similar to hollow points, but with a softer lead tip.
- Tracer Rounds: Contain a pyrotechnic compound that ignites upon firing, allowing the shooter to see the bullet’s trajectory.
- Armor-Piercing (AP): Designed to penetrate armor and other hard targets.
The choice of ammunition type can significantly affect the AK-47’s performance in different scenarios. For example, hollow point rounds may be preferred for self-defense due to their increased stopping power, while armor-piercing rounds may be necessary for engaging armored targets. The selection of what ammo does AK47 use depends heavily on the intended application.
Factors Influencing Ammunition Choice
Several factors influence the choice of ammunition for an AK-47, including:
- Intended Use: Whether for military, law enforcement, hunting, or self-defense.
- Availability: The availability and cost of different types of ammunition.
- Legal Restrictions: Some types of ammunition may be restricted or prohibited in certain jurisdictions.
- Personal Preference: Some shooters may prefer certain types of ammunition based on their experience and performance.
Understanding these factors is essential for making informed decisions about what ammo does AK47 use in specific situations.
