* **Bullet Diameter:** 7.92mm (.312 inches)
* **Case Length:** 39mm
* **Overall Length:** ~56mm
Historical Context and Development
The 7.62x39mm cartridge was developed in response to the need for an intermediate cartridge that could provide better range and accuracy than pistol rounds but with less recoil than full-power rifle cartridges. The Soviet military sought a round that would be effective in close-quarters combat while still offering sufficient range for engagements at moderate distances. The result was the 7.62x39mm, which quickly became a staple of Soviet and Warsaw Pact forces.
Variations and Types of 7.62x39mm Ammunition
Several variations of the 7.62x39mm cartridge exist, each designed for specific purposes. These include:

Detailed Features Analysis of the 7.62x39mm Cartridge
The 7.62x39mm cartridge possesses several key features that contribute to its effectiveness and widespread use.
1. Bullet Weight
* **What it is:** The weight of the bullet, typically measured in grains (gr). Common bullet weights for 7.62x39mm range from 122 to 125 grains.
* **How it works:** Heavier bullets tend to have better ballistic coefficients, meaning they retain energy and resist wind drift more effectively. Lighter bullets may offer higher velocities.
* **User Benefit:** The bullet weight affects the cartridge’s trajectory, recoil, and terminal performance. Users can choose bullet weights based on their specific needs, such as hunting or target shooting.
* **Example:** A 123-grain bullet is a common choice for general-purpose shooting, offering a balance of velocity and energy.
2. Muzzle Velocity
* **What it is:** The speed at which the bullet exits the barrel, measured in feet per second (fps).
* **How it works:** Higher muzzle velocities typically result in flatter trajectories and increased energy transfer to the target.
* **User Benefit:** Higher velocities can improve accuracy and effectiveness at longer ranges.
* **Example:** The 7.62x39mm cartridge typically has a muzzle velocity of around 2,350 fps.
3. Muzzle Energy
* **What it is:** The kinetic energy of the bullet as it leaves the barrel, measured in foot-pounds (ft-lbs).
* **How it works:** Muzzle energy is a key indicator of the cartridge’s potential stopping power.
* **User Benefit:** Higher muzzle energy can improve the cartridge’s effectiveness against targets, particularly in hunting and self-defense scenarios.
* **Example:** The 7.62x39mm cartridge typically has a muzzle energy of around 1,550 ft-lbs.
4. Cartridge Case Material
* **What it is:** The material used to construct the cartridge case, typically brass or steel.
* **How it works:** Brass cases are more expensive but offer better corrosion resistance and reloadability. Steel cases are more affordable but less corrosion-resistant.
* **User Benefit:** The choice of case material can affect the cartridge’s reliability and longevity.
* **Example:** While brass cases are preferred for reloading, steel cases are commonly used in military applications due to their cost-effectiveness.
5. Primer Type
* **What it is:** The type of primer used to ignite the propellant, typically Berdan or Boxer.
* **How it works:** Boxer primers are more common in the United States and are reloadable. Berdan primers are more common in Eastern European countries and are generally not reloadable.
* **User Benefit:** The primer type affects the cartridge’s reloadability and availability.
* **Example:** Most commercially available 7.62x39mm cartridges in the US use Boxer primers.
6. Bullet Construction
* **What it is:** The design and materials used to construct the bullet, such as full metal jacket (FMJ), hollow point (HP), or soft point (SP).
* **How it works:** Different bullet constructions are designed for specific purposes, such as penetration, expansion, or fragmentation.
* **User Benefit:** The bullet construction affects the cartridge’s terminal performance and suitability for different applications.
* **Example:** FMJ bullets are used for general-purpose shooting and military applications, while HP bullets are used for hunting and self-defense.
7. Propellant Type
* **What it is:** The type of gunpowder used to propel the bullet, such as single-base, double-base, or triple-base.
* **How it works:** Different propellants offer varying burn rates and energy output, affecting the cartridge’s velocity and pressure.
