300 BLK vs 7.62 Origins

300 Blackout and 7.62×39 are two popular cartridges used in rifles and other firearms. While they have some similarities, they also have distinct differences that set them apart.

300 Blackout is a relatively new cartridge, developed by Advanced Armament Corporation (AAC) in 2011. It is based on the 5.56x45mm NATO cartridge, but with a larger case and bullet diameter. It was designed with the intention of creating a more powerful round that could be used in an AR-15 platform without the need for extensive modifications. This is achieved by using .308 caliber bullets in a modified 5.56mm case.

On the other hand, 7.62×39 is a more established cartridge that has been in use since the 1940s. It was originally designed by the Soviet Union and is still used in many of their military rifles. It has a larger case and bullet diameter than the 5.56x45mm NATO cartridge, but smaller than the 300 Blackout.

Aerodynamics and Reliability: 300 Blackout vs 7.62×39

7.62×39 has an average BC of 0.27, so it is not a very aerodynamic round compared to other calibers. However, there are some specialized 7.62×39 rounds with higher BCs, such as the Hornady V-Max with a BC of 0.34. Overall, the 7.62×39 is not known for its long-range accuracy or accuracy at extreme distances due to its relatively low BC.

Effective Range: 300 Blackout vs 7.62

One of the main differences between these two cartridges is their effective range. Some 300 Blackout bullets that have a lighter weight or grain have a longer effective range of around 400-600 yards. While most 7.62×39 has a maximum effective range of around 400 yards. This is due to the wider variety of grains within the 300 Blackout family. A lighter weight or grain allows 300 Blackout to retain their energy and velocity over longer distances.

Ballistics: 300 Blackout vs 7.62

Another significant difference is the ballistics. The 300 Blackout has a higher muzzle velocity and energy, making it more powerful and able to take down larger game. It also has less bullet drop and drift, making it more accurate and easier to shoot at longer distances. The 7.62×39, while still powerful, has a slower muzzle velocity and less energy, making it better suited for shorter ranges. 300 has a vastly superior BC and sectional density.

Cartridge Difference: 300 Blackout vs 7.62

There is also a difference in the types of bullets available for each cartridge. The 300 Blackout has a wider variety of bullet weights and designs. These variants include subsonic rounds and supersonic rounds making 300 BLK more versatile for different shooting needs. 7.62×39 typically uses full metal jacket (FMJ) bullets, making it better suited for target shooting and military use.

Lastly, there is a difference in availability and cost between 300 Blackout vs 7.62×39. While both cartridges are relatively easy to find, the 7.62×39 is more widely available and typically less expensive than the 300 Blackout. It is important to note the current ban on 7.62×39 in the United States as of 2023.

300 Blackout and 7.62×39 are two distinct cartridges with different strengths and purposes. The 300 Blackout offers longer range, higher ballistics, and more versatility, while the 7.62×39 is widely available and cost-effective. Ultimately, the choice between these two cartridges will depend on the individual’s needs and preferences.

30-30 vs 300 Blackout vs 7.62×39

The .30-30 Winchester starts off with significantly more kinetic energy, but the .300 Blackout and 7.62x39mm bullets have a much higher ballistic coefficient.

300 Blackout Offers More Versatility In Terms Of Bullet Selection

Both the 300 Blackout and the 7.62×39 are popular cartridges used for hunting, target shooting, and self-defense. While they are similar in some ways, there are also several notable differences between the two.

Bullet Selection:

One of the main advantages of the 300 Blackout is its versatility in terms of bullet selection. It can accommodate a wide range of bullet weights, from 110 grains to 220 grains. This variety in bullet weights and styles makes it a suitable choice for different purposes, such as hunting or long-range shooting. The 7.62×39, on the other hand, has a more limited bullet selection, typically ranging from 123gr, 147gr, and 154gr. This can be a disadvantage for those who want more options for their shooting needs.

Ballistics and Performance:

While both cartridges have similar bullet weights, the 300 Blackout typically has a higher muzzle energy and velocity compared to the 7.62×39. This can result in a flatter trajectory, making it more suitable for longer-range shooting.

However, the 7.62×39 has a heavier bullet and more energy at shorter ranges, making it a more potent choice for hunting medium-sized game at close distances. It also has better penetration and stopping power compared to the 300 Blackout.


Another advantage of the 300 Blackout is its compatibility with AR-15 rifles. By simply changing the barrel, a rifle chambered in 5.56 NATO can be converted to a 300 Blackout, making it a versatile and adaptable choice for shooters. The 7.62×39, on the other hand, is primarily used in AK47s or similar rifles. This factor limits its compatibility and versatility.

Price and Availability:

When it comes to price and availability, the 7.62×39 has the upper hand. Due to its popularity and widespread use, ammunition and rifles chambered in 7.62×39 are generally more affordable and easier to find compared to 300 Blackout. However, the price difference between the two has been decreasing in recent years, making 300 Blackout a more viable option for shooters. Sanctions are making 7.62×39 harder to find although they may be cheaper. 300 Blackout is often times more expensive than 7.62, however, easier to find.

In conclusion, the 300 Blackout offers more versatility in terms of bullet selection and reloading, making it a better choice for those who want a more adaptable cartridge. However, the 7.62×39 has better performance at shorter ranges and is more widely available and affordable. Ultimately, the choice between the two will depend on the shooter’s specific needs and preferences.


Reloading is another aspect where the 300 Blackout outshines the 7.62×39. The former uses standard boxer-primed brass, which makes it easier and more cost-effective to reload. Furthermore, the 300 Blackout has a steeper shoulder angle than the 7.62×39, which can result in smoother feeding and less jamming.

On the other hand, the 7.62×39 uses berdan-primed brass, which can be challenging to find and more expensive compared to boxer-primed brass. Reloading berdan-primed brass is also quite tricky, as it requires specialized tools and techniques.

Boxer vs. Berdan Primers

Now, getting to the difference between Boxer and Berdan primers.

Boxer primers have a single central flash hole and a single internal anvil, making them easy to reload. The flash hole is aligned with the anvil, ensuring a consistent and efficient ignition process. This design also allows for the removal and replacement of the primer in case of a misfire.

On the other hand, Berdan primers have multiple smaller flash holes arranged around the primer pocket, and the anvil is built into the casing itself. This makes them more complex to reload and also more difficult to remove and replace in case of a misfire. However, this design allows for a larger primer pocket, allowing for more reliable ignition in larger cartridges.
