Its widespread use in military rifles has made it one of the most common cartridges in the world. This cartridge has been used in many conflicts, and is a popular choice for many shooters.
Ballistic Performance: A Head-to-Head Comparison
To determine which cartridge is “stronger,” we need to analyze their ballistic performance characteristics. This includes muzzle velocity, muzzle energy, bullet weight, and trajectory.
Muzzle Velocity: Speed Kills
Muzzle velocity refers to the speed of the bullet as it exits the barrel. Generally, a higher muzzle velocity translates to a flatter trajectory and greater energy transfer to the target.
* **.308 Winchester:** Typically, .308 Winchester rounds achieve muzzle velocities ranging from 2600 to 2800 feet per second (fps), depending on the bullet weight and load.
* **7.62x39mm:** The 7.62x39mm typically achieves muzzle velocities ranging from 2300 to 2400 fps.
**Advantage:** .308 Winchester
Muzzle Energy: Impact Power
Muzzle energy is a measure of the kinetic energy of the bullet at the muzzle. It is often used as an indicator of the cartridge’s potential stopping power.
* **.308 Winchester:** .308 Winchester rounds typically produce muzzle energies ranging from 2600 to 2800 foot-pounds (ft-lbs).
* **7.62x39mm:** The 7.62x39mm typically produces muzzle energies ranging from 1500 to 1600 ft-lbs.
**Advantage:** .308 Winchester
Bullet Weight: Mass Matters
Bullet weight influences the bullet’s trajectory, penetration, and resistance to wind drift.
* **.308 Winchester:** .308 Winchester bullets typically range in weight from 150 to 180 grains, with some loads exceeding 200 grains.
* **7.62x39mm:** 7.62x39mm bullets typically weigh around 123 grains.
**Advantage:** .308 Winchester (due to wider availability of heavier bullet options)
Trajectory: The Path to the Target
Trajectory refers to the path of the bullet in flight. A flatter trajectory allows for easier aiming and greater accuracy at longer ranges.

**Advantage:** .308 Winchester
Effective Range: Where the Cartridges Shine
Effective range is the distance at which a cartridge can reliably and accurately hit a target with sufficient energy to cause the desired effect. This range is based on a multitude of factors. The .308 round is the clear winner here.
* **.308 Winchester:** The .308 Winchester has an effective range of up to 800-1000 yards, making it suitable for long-range shooting and hunting.
* **7.62x39mm:** The 7.62x39mm has an effective range of around 300-400 yards, making it best suited for close to medium-range engagements.
**Advantage:** .308 Winchester
Recoil: Managing the Kick
Recoil is the backward force exerted by the firearm when firing. Excessive recoil can affect accuracy and shooter comfort.
* **.308 Winchester:** The .308 Winchester produces moderate to heavy recoil, depending on the rifle weight and load. The recoil can be managed with proper technique and recoil-reducing devices.
* **7.62x39mm:** The 7.62x39mm produces lighter recoil than the .308 Winchester, making it easier to control, especially in lightweight rifles.
