.308 vs. 7.62x39
Key Differences and Choosing the Right Caliber
When it comes to rifle cartridges, the .308 Winchester and the 7.62x39mm are two of the most widely discussed rounds in the world. Both are excellent in their own right, and fairly similar to each other, but in all reality they serve vastly different purposes. In this article, our team at Core Vision Training will dive into the critical differences between these two calibers, their applications, and factors to consider when choosing between them.
Let’s dive in.
Origins and Design
The .308 Winchester, introduced in the 1950s, is a high-powered rifle cartridge developed for long-range precision and hunting. It is the civilian counterpart of the 7.62x51mm NATO round, widely used by military forces worldwide. Known for its versatility, the .308 excels in hunting, competitive shooting, and tactical applications. It has been a favorite among hunters and marksmen for decades, thanks to its ability to maintain accuracy over long distances.
The 7.62x39mm, developed by the Soviet Union during World War II, is synonymous with the iconic AK-47. This intermediate cartridge is compact and designed for reliable performance in semi-automatic and fully automatic rifles. Its rugged design and widespread adoption have made it a staple in military and civilian use for decades.
The cartridge’s history is closely tied to its role in arming militaries around the world, cementing its reputation as a workhorse.
Ballistics Comparison
Velocity and Energy:
The .308 Winchester generates higher muzzle velocity, typically ranging from 2,600 to 2,800 feet per second (fps), and delivers impressive energy between 2,500 and 2,800 foot-pounds (ft-lbs). This high performance makes it ideal for long-range shooting and taking down large game animals.
The 7.62x39mm, in contrast, achieves muzzle velocities around 2,300 fps and energy levels of approximately 1,500 ft-lbs. While it lacks the sheer power of the .308, it’s sufficient for medium game hunting and close to mid-range engagements.
Trajectory:
The .308 has a flatter trajectory, which allows for precise targeting at distances beyond 500 yards. Its ballistic performance ensures minimal bullet drop over long distances, a critical factor for marksmen and hunters.
The 7.62x39mm experiences more pronounced bullet drop, particularly beyond 300 yards. This limits its effectiveness at extended ranges but makes it highly reliable within shorter distances.
Recoil:
The .308 produces noticeable recoil due to its higher energy. While manageable for experienced shooters, it can be intimidating for beginners or those who prioritize comfort.
The 7.62x39mm’s lighter recoil makes it more shooter-friendly, particularly for extended sessions or for those new to firearms. Its lower recoil also aids in faster follow-up shots.
Use Cases

Hunting:
The .308 is a powerhouse for hunting large game such as deer, elk, and bear. Its long-range accuracy and stopping power allow hunters to take ethical shots from significant distances, ensuring a clean kill.
The 7.62x39mm is better suited for medium game, such as hogs and deer, at ranges under 200 yards. It’s a popular choice for hunters in dense woods or brush where long-range shots are unnecessary.
Home Defense and Tactical Use:
The 7.62x39mm excels in home defense and tactical scenarios. Its moderate power and use in compact platforms like the AK-47 and SKS make it effective in close-quarters situations. The round’s ability to penetrate barriers without excessive over-penetration adds to its practicality in defensive roles.
The .308, while powerful, is generally overkill for home defense. Its high penetration can pose risks in urban or suburban environments, where collateral damage is a concern.
Recreational Shooting:
Both calibers are excellent for recreational shooting, but the 7.62x39mm stands out for its affordability. Bulk ammunition is widely available, making it ideal for plinking and practice sessions.
The .308, though more expensive, offers a premium shooting experience. Its precision and power are perfect for those seeking a more challenging and rewarding range session.
Availability and Cost
Ammunition:
The 7.62x39mm is one of the most cost-effective rifle cartridges on the market. Its widespread use ensures a steady supply and competitive pricing, often costing half as much per round as the .308.
The .308, while more expensive, offers a broader range of bullet types and premium loads. This versatility allows shooters to select ammunition tailored to their specific needs, whether for hunting, target shooting, or tactical applications.
Firearms:
Rifles chambered in 7.62x39mm, such as the AK-47 and SKS, are generally more affordable than their .308 counterparts. These rifles are known for their rugged reliability and simplicity, making them a popular choice for budget-conscious shooters.
The .308 Winchester is commonly chambered in bolt-action hunting rifles and semi-automatic platforms like the AR-10. While these firearms tend to be more expensive, they often come with superior accuracy and build quality.
Factors to Consider
Purpose:
If your primary goal is long-range hunting or precision shooting, the .308 Winchester is the clear choice. Its flat trajectory, high energy, and accuracy make it ideal for these applications.
For shorter-range engagements, home defense, or casual shooting, the 7.62x39mm offers a more practical and cost-effective solution.
Shooting Environment:
Open terrains and long distances favor the .308, while the 7.62x39mm is better suited for dense woods or urban environments.
Budget:
The 7.62x39mm is the more economical option, both in terms of ammunition and firearms. It’s a great choice for those just starting out or looking to maximize their shooting time without breaking the bank.
The .308 requires a higher initial investment but delivers unmatched versatility and performance for serious shooters.
