7.62x39 vs .308: Which Cartridge Is Right for You?
The .308 Winchester is the clear choice for long-range shooting and big game hunting, generating roughly 2,700 ft-lbs of muzzle energy compared to about 1,500 ft-lbs for 7.62x39, according to ballistics data from Bear Creek Arsenal.
The 7.62x39 pulls ahead on cost, recoil, and platform affordability.
The .308 produces close to three times the recoil energy of the 7.62x39 on average, according to comparison testing from Sniper Country, and AK-pattern rifles chambered in 7.62x39 typically cost far less to buy and feed than a comparable .308 rifle.

7.62x39 Ammo Overview
The 7.62x39mm cartridge was developed by the Soviet Union during World War II and introduced in 1943. Designed by a team led by Nikolai Elizarov and Boris Semin, it was intended as an intermediate cartridge that balanced the power of traditional rifle ammunition with more manageable recoil.
It was initially associated with the SKS rifle and later became famous as the cartridge of the AK-47.
Typical 7.62x39mm ammunition uses a .310–.312-inch bullet, commonly weighing 122–154 grains, with muzzle velocities around 2,350 feet per second, depending on the load according to ballistics figures from Ammo.com's cartridge database.
Its combination of moderate recoil, practical medium-range performance, and reliable operation helped make it one of the world's most widely produced rifle cartridges.
Although rooted in military use, the cartridge also became popular among civilian shooters. It is used for recreational shooting, competition, and hunting medium-sized game such as deer and hogs where permitted.
Modern ammunition is produced with several bullet types, including full metal jacket (FMJ) loads commonly used for target shooting and soft-point (SP) or hollow-point (HP) loads intended for applications such as hunting.
More than eight decades after its introduction, the 7.62x39mm remains internationally recognized for its historical importance, widespread availability, manageable recoil, and close association with the AK-pattern rifle.
.308 Winchester Ammo Overview
The .308 Winchester was introduced by Winchester in 1952 as a compact, modern alternative to the .30-06 Springfield, offering similar ballistic performance in a shorter case.
A closely related military cartridge, the 7.62x51mm NATO, was adopted shortly afterward in the 1950s and became a standard chambering for numerous military rifles and machine guns.
Typically loaded with 150- to 180-grain bullets, the .308 Winchester combines substantial power, manageable recoil, and consistent accuracy. These characteristics have helped establish it as one of the world's most widely used cartridges for hunting and precision rifle shooting.
Hunters commonly use the .308 Winchester for medium to large game, while target and competitive shooters value its predictable ballistics and broad selection of match ammunition. Depending on the rifle, ammunition, environmental conditions, and shooter, the cartridge is also used for precision shooting at extended ranges.
Today, manufacturers offer a wide variety of .308 Winchester and 7.62x51mm NATO loads, including soft-point hunting ammunition, match bullets, and full metal jacket (FMJ) ammunition for sporting and training applications.
Although the two cartridges are closely related, their specifications are not completely identical, so shooters should use ammunition appropriate for their firearm's marked chambering and manufacturer guidance.
More than seven decades after its introduction, the .308 Winchester remains a major hunting, sporting, and precision-rifle cartridge, valued for its versatility, accuracy, widespread availability, and long-established performance.
Head-to-Head Comparison
Velocity, Energy, and Trajectory
The .308's larger case capacity and higher operating pressure let it drive heavier bullets at substantially higher velocity.
At the muzzle, the .308 generates roughly 2,700 ft-lbs of energy versus around 1,500 ft-lbs for 7.62x39, according to Bear Creek Arsenal's comparison data.
That gap widens with distance: at 300 yards, the .308 still carries close to double the retained energy of the 7.62x39.
Trajectory and Effective Range
Sportsman's Warehouse's ballistics comparison shows the .308 dropping about 8.5 inches at 300 yards versus roughly 14 inches for 7.62x39, and the gap grows further at 400 yards.
The .308's higher ballistic coefficient, averaging around 0.434 compared to roughly 0.27 for 7.62x39 according to Sniper Country's testing, is the main driver of that flatter trajectory.
Recoil and Platform
Sniper Country's recoil testing found the .308 produces close to three times the recoil energy of 7.62x39 on average.
The 7.62x39's low recoil and light weight per round make it well suited to high-volume shooting in an AK or SKS, while the .308 dominates in AR-10 and bolt-action hunting rifles built for range and power over volume.
Which Should You Choose?
Big Game and Long-range Hunting
- Choose .308 Winchester for its flatter trajectory and significantly higher retained energy past 200 yards.
Budget-friendly High-volume Shooting
- Choose 7.62x39, especially through an AK-pattern rifle, where steel-cased ammunition keeps cost per round low.
Close-range Defense or Hog Hunting
- 7.62x39 delivers adequate energy inside 150 to 200 yards at a fraction of the recoil and cost of .308.
Bottom Line: The .308 Winchester wins on power and range for hunting and precision shooting, while 7.62x39 wins on cost, recoil, and volume shooting in an AK or SKS platform.

Frequently Asked Questions
Question: Can a rifle chambered in .308 fire 7.62x39?
Answer: No. These are entirely different cartridges with different case dimensions, and 7.62x39 will not chamber or fire safely in a .308 rifle.
Question: Is 7.62x39 as powerful as .308?
Answer: No. The .308 generates nearly double the muzzle energy of 7.62x39 and retains significantly more energy at range, making it the more powerful cartridge by a wide margin.
Question: Why is 7.62x39 cheaper to shoot than .308?
Answer: Most 7.62x39 ammunition is manufactured with inexpensive steel cases and produced in high volume for AK-pattern rifles, while .308 is typically brass-cased and loaded to more demanding hunting and precision standards.
Question: Is 7.62x39 good enough for deer hunting?
Answer: Yes, at close range. 7.62x39 works for deer inside about 150 to 200 yards with an expanding soft point bullet, but the .308 is the stronger choice for hunting at longer distances.
