The .308 is known for its accuracy, versatility, and stopping power, making it a favorite among hunters, target shooters, and law enforcement professionals.
## Deep Dive: 7.62×39 vs .308 – A Detailed Comparison
To truly understand the **7.62×39 vs .308 what’s the difference**, we need to delve into the specific characteristics of each cartridge. This section will explore ballistics, recoil, effective range, and other key factors that differentiate these two rounds.
### Ballistics and Performance
The ballistic performance of a cartridge is a crucial factor in determining its suitability for a particular application. Let’s examine the key ballistic characteristics of the 7.62×39 and the .308 Winchester.
* **Velocity:** The .308 Winchester generally exhibits higher velocities than the 7.62×39. This translates to a flatter trajectory and greater energy retention at longer ranges. Common .308 loads can achieve muzzle velocities of around 2600-2800 fps, while 7.62×39 typically ranges from 2300-2400 fps.
* **Energy:** The .308 Winchester delivers significantly more energy than the 7.62×39. This is due to its larger bullet diameter, heavier bullet weights, and higher velocities. The .308 can generate muzzle energies of around 2600-2800 ft-lbs, while the 7.62×39 typically produces around 1500-1600 ft-lbs.
* **Trajectory:** Due to its higher velocity and ballistic coefficient, the .308 Winchester exhibits a flatter trajectory than the 7.62×39. This means that the .308 will drop less over a given distance, making it easier to hit targets at longer ranges. Our testing shows a noticeable difference in bullet drop beyond 200 yards.
* **Ballistic Coefficient:** The .308 typically has a higher ballistic coefficient, allowing it to resist wind drift and maintain velocity better at longer ranges. This is a significant advantage for long-range shooting.
### Recoil
Recoil is another important factor to consider, especially for new shooters or those sensitive to recoil. The 7.62×39 produces significantly less recoil than the .308 Winchester. This makes it easier to control the rifle and maintain accuracy, especially during rapid fire. The .308, with its greater power, delivers a more substantial recoil impulse. Experienced shooters often prefer the .308’s power, while those seeking more manageable recoil may opt for the 7.62×39. Based on expert consensus, recoil management is key to accurate shooting, regardless of the cartridge.
### Effective Range
The effective range of a cartridge is the distance at which it can reliably and accurately hit a target with sufficient energy to cause the desired effect. The .308 Winchester has a significantly longer effective range than the 7.62×39. The .308 can be effectively used out to 800 yards or more, while the 7.62×39 is typically limited to around 300-400 yards. This difference in effective range is primarily due to the .308’s higher velocity, flatter trajectory, and greater energy retention.
### Firearm Availability and Cost
Firearm availability and ammunition cost are also important considerations. Both the 7.62×39 and the .308 Winchester are widely available, but the specific types of firearms chambered in each cartridge may vary.
* **7.62×39:** Primarily associated with AK-pattern rifles, SKS rifles, and some bolt-action rifles. Ammunition is generally more affordable than .308.
