What is 7.62×39?

The 7.62×39 cartridge was introduced in 1944 and represents an early intermediate cartridge. While the intermediate 7.92×33 Kurz precedes the 7.62×39, the latter is still in common use today while the other has been completely phased out of conventional usage. The cartridge officially entered service in 1945 and served as the standard issue military cartridge for the Soviets for most of the Cold War, still seeing some limited usage today. Beyond the Soviet Union, countless other countries on nearly every continent have utilized the cartridge in one form or another. This is mainly due to the fact that many surplus firearms worked their way around the globe as newer equipment became available and countries sold off or exported surplus arms.

The round was developed by the Soviets to address the desire for an intermediate cartridge which could be utilized in a variety of different weaponry. The goal was for infantry arms such as a light machine gun, semi-automatic carbine, and select-fire rifle to utilize the same cartridge. This mission was achieved and made manifest with designs such as the SKS, AK-47, and RPD and RPK light machine guns.

Among civilian shooters, the cartridge is a staple, particularly among milsurp shooters and AK enthusiasts. Before some of the recent sanctions and gun control laws which were passed in recent decades, 7.62×39 ammunition and firearms chambered in the caliber were both prevalent and extremely affordable. Stories of sub $100-dollar Russian SKS rifles and heaps of 7.62×39 spam cans are common from the 1980’s and early 1990’s. In today’s market, many of the old surplus arms have seen significant price hikes due to things such as sanctions and supplies generally waning over the years. Modern production firearms chambered in the 7.62×39 continue to keep the cartridge relevant and in common usage.


What is 5.45×39?

The 5.45×39 cartridge was developed in 1974 for use with the AK-74 rifle. The cartridge was intended to replace the currently issued 7.62×39 round and perform similarly to the West’s 5.56x45m NATO round. By going to a smaller diameter projectile, higher velocities could be achieved. Simply put, what the 5.45×39 may lack in mass when compared to the 7.62×39, it makes up for in its velocity and extended effective range. A lighter projectile traveling at higher velocities allows for a higher degree of penetration as well, a factor which was important to the Soviets during the Cold War era. Both the 5.45×39 and 5.56x45mm NATO loadings like the M855 “green tip” round were designed to have good effect on target when up against body armor of the Cold War era.

Like its predecessor, the 5.45×39 has been utilized in a wide variety of firearms. Everything from mainline service rifles such as the AK-74 and AK-12 to shorter firearms like Krinkovs and even RPK light machine guns in the cartridge. The 5.45×39 essentially sought to be the Soviet’s answer to the 5.56x45mm NATO round. Many 5.45×39 loadings were developed for military usage such as the multiple 7N6 designations designed to have good effect on body armor.

Civilian shooters adore the 5.45×39 cartridge and AK-74 pattern rifles are some of the most popular firearms in the world of AKs. Shooters enjoy the light recoil of the 5.45×39 and find it to be a capable and handy cartridge. Unfortunately, this round has been harder to get ahold of lately, mainly due to sanctions and the lack of widespread production enjoyed by something like the 7.62×39. Recent sanctions and scarcity of ammunition has led many 74 owners to divest themselves of their 5.45×39 ammunition and rifles. This painful reality was observed on forums such as The AK Files within recent years. That being said, we are finally seeing more importation of the round while domestic companies are committing to manufacturing the cartridge.

How Available is 5.45×39 Ammunition?

At this point in time, there is significantly less 5.45×39 ammunition offerings available than there are options for 7.62×39. Simply put, there are less companies producing the cartridge and the supply of the round has been impacted heavily by sanctions. Companies such as Wolf and TulAmmo used to consistently bring in steel cased 5.45×39 ammunition prior to import restrictions. At this point in time, companies such as TelaAmmo have started mass importation of the cartridge, helping increase the supply of 5.45×39 in the United States. Domestic companies have also announced plans to produce ammunition in this caliber, another factor which will aid in increasing the supply of 5.45×39 ammunition. At this point in time, while scarce, the 5.45×39 round is not dead. Ammunition is coming in and gradually becoming more available, meaning that we will hopefully have a sable supply of 5.45×39 ammunition again.
