The AK-47: The World’s Most Famous Rifle
The AK-47, with its distinct silhouette and widespread use, has become an instantly recognizable symbol of the 20th and 21st centuries. From battlefields to insurgent groups, the rifle’s rugged design and reliability have cemented its place in history. A key element of this legendary firearm is, of course, the ammunition it fires. So, what size bullet does an AK-47 shoot? The answer, as we’ll explore, is central to understanding its power and impact.
The Heart of the Matter: The Standard Round
The AK-47, in its most common configuration, primarily utilizes a specific type of bullet known as the 7.62x39mm cartridge. This is the “what size bullet does an AK-47 shoot” answer most people seek, and it’s crucial to understanding the rifle’s capabilities.
The 7.62x39mm round is a product of post-World War II Soviet design. It represents a deliberate effort to balance the power of a larger rifle cartridge with the manageable recoil and effective range of an intermediate round. This balance contributed significantly to the AK-47’s success.
Breaking Down the Dimensions
Let’s examine the 7.62x39mm cartridge in more detail. Understanding the dimensions helps explain the round’s performance:
Bullet Diameter: The 7.62mm designation refers to the approximate diameter of the bullet itself, measured in millimeters. In reality, this is often closer to 7.92mm, though the measurement convention is standardized at 7.62mm.
Case Length: The 39mm portion of the name indicates the length of the cartridge case. This case houses the propellant, the explosive material that fuels the bullet’s journey down the barrel.
Bullet Weight: The weight of the bullet itself varies. The most common bullet weight is in the range of approximately 123 to 124 grains, though heavier and lighter options exist for specialized applications.
The overall length of a loaded cartridge is typically in the range of 56 mm.
The Birth of a Champion: The Origins of the 7.62x39mm
The 7.62x39mm round was developed by the Soviet Union in the aftermath of World War II. The Soviets recognized the need for a cartridge that bridged the gap between the powerful, full-size rifle rounds used in their service rifles and the less powerful pistol rounds used in submachine guns. The resulting 7.62x39mm cartridge aimed to be more effective than the submachine gun cartridges at longer ranges.
The choice of this cartridge was a strategic decision. It allowed for more manageable recoil, enabling better control during automatic fire than the larger caliber rounds. The round also possessed sufficient power to effectively engage targets at medium ranges. The 7.62x39mm’s ballistic characteristics were well-suited for the close-quarters combat and the types of engagements that Soviet military strategists anticipated.
Understanding the Power: Ballistic Performance
The 7.62x39mm round offers a specific set of performance characteristics that contribute to the AK-47’s battlefield effectiveness.
Muzzle Velocity
The velocity at which a bullet leaves the muzzle of the barrel of the AK-47 is critical for determining the round’s trajectory and impact. The 7.62x39mm usually reaches muzzle velocities exceeding approximately 710 meters per second.
Effective Range
The effective range is the distance at which the round can be expected to reliably hit a target and retain sufficient energy to inflict damage. The 7.62x39mm’s effective range is typically cited as approximately 300-400 meters. At this range, the round can still deliver significant kinetic energy.
Energy at Impact
The energy with which a bullet impacts a target is a key factor in its wounding capabilities. The 7.62x39mm round delivers significant energy upon impact. This energy transfer, coupled with the bullet’s design, contributes to the round’s effectiveness in incapacitating a target.
The Impact on Target: Understanding the Wound Profile
The 7.62x39mm round, like any firearm cartridge, causes damage through kinetic energy transfer. This energy transfer leads to a wound profile, which is the pattern of tissue damage resulting from the bullet’s passage through the body. While the specifics of wound ballistics are complex, some general observations can be made:
Penetration: The 7.62x39mm round has a good penetration capability. This means it can pass through various barriers and still have sufficient energy to reach the target.
Tissue Damage: The round’s relatively high energy can cause significant tissue disruption upon impact.
Stopping Power: Stopping power, in this context, refers to the bullet’s ability to immediately incapacitate a target. The 7.62x39mm provides a solid level of stopping power.
General Wounding Effects: The bullet’s velocity and design can lead to a wound channel, with the size and shape of the channel affected by the bullet’s behavior upon impact.
Variations on a Theme: AK-47 Variants and Alternate Calibers
It is important to note that the AK-47 has seen numerous iterations and variations throughout its history. These variations often use different ammunition, thus impacting the question of “what size bullet does an AK-47 shoot.”
The AK-74
The AK-74 represented a shift. It utilizes the 5.45x39mm cartridge. This round is smaller in diameter, has a higher velocity, and is designed to provide improved accuracy at longer ranges compared to the 7.62x39mm. It is very important to note that the AK-74 is still an AK platform.
Beyond the Standard
In some cases, you may find AK-47s, AK platform rifles chambered in other calibers. These are rarer and often used for specific purposes or in specific markets. They usually are not mass produced and are very specific to the circumstances.
The Ammunition Marketplace: Availability and Uses
The 7.62x39mm cartridge remains widely available around the world, contributing to the AK-47’s continued popularity.
Commercial Availability
The round is readily available for purchase, both domestically and internationally.
Ammunition Cost
The 7.62x39mm round tends to be more affordable than some other rifle rounds.
Bullet Types
Various bullet types are available, including full metal jacket (FMJ) rounds for general use, hollow-point (HP) rounds designed for expansion upon impact, and soft-point (SP) rounds.
Global Distribution
The 7.62x39mm cartridge is found in nearly every corner of the world, a testament to the AK-47’s global reach.
Considering the Uses
The AK-47 and its ammunition have seen use in a variety of contexts:
Military Applications
The AK-47, chambered in 7.62x39mm, has served as the standard service rifle for numerous militaries around the world.
