The Heart of the Matter: The Standard Caliber
When discussing the AK-47, the answer to the question “What caliber does AK-47 shoot” is almost universally agreed upon: the 7.62x39mm cartridge. This particular round is the lifeblood of the classic AK-47 design, the ammunition that feeds its powerful and iconic presence. It’s critical to understand what “7.62x39mm” signifies. The “7.62” refers to the diameter of the bullet itself, measured in millimeters. It’s approximately 7.62 millimeters, or roughly .30 inches. The “39mm” signifies the length of the cartridge case. So, in essence, the 7.62x39mm cartridge consists of a bullet that is 7.62mm in diameter, housed within a 39mm-long casing.
The selection of the 7.62x39mm cartridge was a deliberate choice by Mikhail Kalashnikov and his design team. This round offered a balance between power, manageable recoil, and effective range, making it well-suited for the conditions and anticipated combat scenarios of the time. The 7.62x39mm round’s ballistic characteristics are key to understanding the AK-47’s effectiveness. The round is designed to deliver substantial power at relatively close to medium ranges. While not reaching the extreme ranges of some rifle cartridges, it offered a more manageable recoil than many other larger rifle cartridges, making it easier to control in automatic fire. This was especially important for a weapon intended to be used by soldiers with varying levels of training.
The 7.62x39mm round typically exits the barrel with a velocity that is slower compared to many other modern military rounds, but it makes up for this with raw power. This power translates into good penetration capabilities, allowing it to effectively pierce wood, light cover, and some levels of body armor. While the 7.62x39mm might not be the most accurate round at extended distances compared to some other rifle rounds, it often exhibits impressive stopping power at combat ranges. This refers to the ability to incapacitate or neutralize a target quickly, which is a crucial aspect of any military weapon. The 7.62x39mm provides an adequate level of stopping power due to its weight and construction.
The AK-47’s acceptance of this particular round has a significant impact on its operational effectiveness.

This design characteristic has been vital to its reputation for dependability. The availability of 7.62x39mm ammunition has also contributed to the AK-47’s widespread use. This cartridge is manufactured globally and can be found in a plethora of locations, making it a readily available resource for both official military forces and civilian markets.
Evolving the Design: Variations and Alternate Choices
The AK-47 story doesn’t end with the standard 7.62x39mm. Over the years, the basic design has been adapted and refined, resulting in a series of variants and offshoots, including other calibers. As military and defense priorities changed, modifications were inevitable.
One of the most significant changes was the introduction of the AK-74, which was developed as a successor to the AK-47. Instead of the 7.62x39mm, the AK-74 was chambered for the 5.45x39mm cartridge. This smaller-diameter round represented a shift towards improved accuracy and flatter trajectories. The intention behind this move was to offer the military an advantage in effectiveness and to take advantage of new developments. This 5.45x39mm round utilizes a smaller bullet, and the cartridge overall is a bit smaller when compared to the 7.62x39mm cartridge. This smaller size allows soldiers to carry more ammunition, which could be a strategic benefit in sustained combat scenarios.
Compared to its predecessor, the 5.45x39mm round generally offers a more accurate trajectory. The 5.45mm projectiles fly flatter, which makes it easier to hit targets at a greater range. However, the stopping power of the 5.45x39mm round is generally lower than that of the 7.62x39mm. Also, it is important to consider that the choice of the 5.45x39mm reflects shifting tactical doctrines and technological advancements.
Beyond the AK-74, there have been other less common AK-47 variations which chamber alternative ammunition. It’s not uncommon to find AK-47s that use other ammunition types. For instance, a limited number of AK platforms have been chambered in 9x39mm, a subsonic round designed to work in concert with silencers. This variant is typically found in special operations scenarios. While less common, it’s a testament to the adaptability of the basic AK design. Also, some AK platforms have been adapted to accept the .223 Remington / 5.56x45mm NATO cartridges to appeal to markets that use these widely available ammunition types. These adaptations are usually intended for export markets or commercial sale, and provide users the ability to use the ammunition of their choice.
The Caliber’s Influence: Reliability and Beyond
