## 7.62×39 vs .308: A Detailed Comparison
To truly understand the **7.62×39 vs .308 what’s the difference**, we need to compare them across several key performance categories.
### Ballistics and Performance
* **Velocity:** The .308 generally has a higher muzzle velocity than the 7.62×39, resulting in a flatter trajectory and greater effective range. This means the .308 will reach the target faster, with less drop over distance.
* **Energy:** The .308 delivers significantly more energy on target than the 7.62×39. This is due to the heavier bullet and higher velocity, making it more effective for taking down larger game.
* **Trajectory:** The .308’s flatter trajectory makes it easier to shoot accurately at longer distances. The 7.62×39 has a more curved trajectory, requiring more holdover for long-range shots.
* **Effective Range:** The .308 has a longer effective range than the 7.62×39. The .308 can effectively reach targets out to 800 yards or more, while the 7.62×39 is typically limited to around 300-400 yards.
### Recoil
The 7.62×39 produces less recoil than the .308. This makes it more comfortable to shoot, especially for extended periods, and easier to control in rapid-fire situations. The .308 has a more substantial recoil, which can be a factor for smaller or less experienced shooters.
### Rifle Platform Availability
* **7.62×39:** Primarily chambered in AK-pattern rifles, SKS rifles, and some bolt-action rifles. AK-pattern rifles are known for their reliability and ruggedness, but may not offer the same level of accuracy as some .308 rifles.
* **.308:** Available in a wide variety of platforms, including bolt-action rifles, AR-10 pattern rifles, and semi-automatic rifles. This gives shooters more options in terms of rifle style, features, and customization.
### Cost and Availability
Generally, 7.62×39 ammunition is less expensive than .308 ammunition, especially in bulk quantities. However, ammunition prices fluctuate, so it’s always best to check current prices from reliable sources. Both cartridges are widely available, but the specific types of ammunition available may vary depending on location and current market conditions.
### Accuracy
While both cartridges can be accurate, the .308 generally has the potential for greater accuracy, especially in well-built bolt-action rifles. The 7.62×39, particularly in AK-pattern rifles, is known for its acceptable, but not exceptional, accuracy. As a rule of thumb, a good shooter with a good platform will be able to obtain better groups with a .308 than with a 7.62×39.
## Real-World Applications: Choosing the Right Cartridge
The best choice between the 7.62×39 and the .308 depends heavily on the intended use. Let’s examine some common scenarios:
### Hunting
* **Medium-Sized Game (Deer, Hogs):** The .308 is generally a better choice for hunting medium-sized game at longer ranges due to its higher energy and flatter trajectory. However, the 7.62×39 can be effective at shorter ranges (under 200 yards) with proper shot placement.
* **Large Game (Elk, Bear):** The .308 is a more suitable option for larger game due to its superior stopping power. The 7.62×39 is not recommended for hunting large, dangerous game.
### Sport Shooting/Target Practice
* **Short-Range Target Shooting:** The 7.62×39 can be a fun and affordable option for short-range target shooting, especially with AK-pattern rifles. Its lower recoil makes it comfortable for extended shooting sessions.
* **Long-Range Target Shooting:** The .308 is the clear winner for long-range target shooting due to its flatter trajectory, higher velocity, and greater accuracy potential. It is a popular choice for precision rifle competitions.
### Self-Defense
Both cartridges can be used for self-defense, but there are factors to consider:
* **Home Defense:** The 7.62×39 offers a good balance of power and controllability for home defense. Its shorter effective range is less of a concern in close-quarters situations. Overpenetration can be a concern with both cartridges, so choosing appropriate ammunition is crucial.
* **Long-Range Self-Defense:** The .308 provides greater range and stopping power for longer-range self-defense scenarios. However, its higher recoil can make it more challenging to control in rapid-fire situations.
### Tactical/Military Applications
The .308 (7.62x51mm NATO) is the standard cartridge for many military and law enforcement applications requiring long-range accuracy and stopping power. The 7.62×39 is still used in some military applications, particularly in regions where AK-pattern rifles are prevalent.
