Understanding AK-47 Ammunition: The 7.62x39mm Cartridge
The most common, and often considered the standard, AK-47 ammunition size is the 7.62x39mm cartridge. This intermediate cartridge was developed by the Soviet Union during World War II and has since become one of the most widely produced and used cartridges in the world. Its design balances manageable recoil with sufficient power for effective use in close to medium-range engagements. The “7.62” refers to the approximate bullet diameter in millimeters, while “39” indicates the case length in millimeters. This is a crucial distinction for safety and proper functioning.
Key Dimensions and Specifications
* **Bullet Diameter:** Approximately 7.92 mm (0.312 inches). Slight variations exist depending on the manufacturer.
* **Case Length:** 39mm (1.535 inches).
* **Overall Length:** Approximately 56mm (2.205 inches).
* **Rim Diameter:** 11.35 mm (0.447 inches).
* **Primer Type:** Typically, Berdan or Boxer, depending on the manufacturer and origin. Berdan primers are more common in military surplus ammunition, while Boxer primers are typically found in commercially produced ammunition.
* **Bullet Weight:** Typically ranges from 122 to 125 grains (8.0 to 8.1 grams).
Evolution and History of the 7.62x39mm
The 7.62x39mm cartridge was developed in the Soviet Union during World War II as a replacement for the 7.62x54mmR rifle cartridge, which was considered too powerful for the new generation of infantry rifles. The 7.62x39mm offered a better balance of power, weight, and recoil, making it ideal for use in the AK-47 assault rifle. The cartridge quickly gained popularity and became the standard ammunition for the Soviet military and its allies. Its widespread adoption cemented its place as a staple in military and civilian applications worldwide.
Beyond 7.62x39mm: Less Common AK-47 Ammunition Sizes
While the 7.62x39mm is the quintessential AK-47 round, it’s important to acknowledge that the AK platform has been adapted to chamber other ammunition sizes. These variations are less common but cater to specific needs or preferences.
5.45x39mm: The AK-74 Variant
Developed as a successor to the 7.62x39mm, the 5.45x39mm cartridge is primarily associated with the AK-74 rifle. It offers a flatter trajectory and reduced recoil compared to its predecessor. While not technically “AK-47 ammunition,” it’s a direct descendant and often discussed in the same context.
* **Bullet Diameter:** 5.60 mm (0.220 inches)
* **Case Length:** 39.85 mm (1.569 inches)
* **Overall Length:** 57 mm (2.24 inches)
* **Bullet Weight:** Typically 53 to 60 grains (3.4 to 3.9 grams).
.223 Remington/5.56x45mm NATO: Aftermarket Conversions
Some AK variants, often aftermarket conversions or produced in countries adhering to NATO standards, are chambered in .223 Remington (also known as 5.56x45mm NATO). This allows for greater ammunition availability in some regions, but it’s crucial to verify the specific chambering of any AK variant before using .223/5.56 ammunition.
* **Bullet Diameter:** 5.70 mm (0.224 inches)
* **Case Length:** 44.70 mm (1.760 inches)
* **Overall Length:** 57.40 mm (2.260 inches)
* **Bullet Weight:** Typically 55 to 77 grains (3.6 to 5.0 grams).
Other Calibers: Niche Adaptations
Less common calibers for AK-pattern rifles exist, often developed for specific markets or purposes. These might include cartridges like 7.62x51mm NATO or shotgun calibers. However, these are highly specialized and not representative of standard AK-47 ammunition sizes.
The Importance of Correct Ammunition Selection
Using the correct ammunition size and type in your AK-47 is paramount for safety, reliability, and accuracy. Incorrect ammunition can lead to malfunctions, damage to the firearm, or even serious injury.
Safety Considerations
* **Chamber Pressure:** Using ammunition with excessive pressure can damage the firearm and potentially cause catastrophic failure.
* **Headspace:** Incorrect headspace (the distance between the bolt face and the cartridge case) can lead to malfunctions or dangerous conditions.
* **Bullet Diameter:** Using a bullet diameter that is too large can cause excessive pressure, while a bullet diameter that is too small can result in poor accuracy and potential damage to the barrel.
Reliability and Functionality
* **Cycling Issues:** Incorrect ammunition can cause failures to feed, extract, or eject, leading to malfunctions and reduced reliability.
* **Accuracy:** Using ammunition that is not properly matched to the firearm can result in poor accuracy and inconsistent performance.
* **Damage to the Firearm:** Using incorrect ammunition can damage the barrel, bolt, or other components of the firearm, potentially rendering it unsafe to use.
Checking Ammunition Compatibility
* **Consult the Firearm’s Manual:** Always refer to the firearm’s manual for the manufacturer’s recommended ammunition specifications.
* **Check the Chamber Marking:** Most firearms have a marking on the barrel or receiver indicating the chambering. Ensure that the ammunition matches this marking.
* **Use a Cartridge Gauge:** A cartridge gauge can be used to verify that the ammunition is within the correct dimensions for the chamber.
