By pulling the bullets from inexpensive ball ammo and replacing them with a suitable expanding bullet, you can improve the 7.62x39's accuracy and terminal performance.

After coming into its own in the horror that was the Eastern Front, the intermediate cartridge concept has slowly fallen out of favor. Although Germany, with its 7.92x33 Kurz, is often considered the originator of this cartridge type, such is not the case. The concept for a true intermediate cartridge was actually conceived in Imperial Russia by weapons designer Vladimir Grigoryevich Fedorov.

Prior to the First World War, Fedorov developed a rimless 6.5mm cartridge driving a 131-grain projectile at 2,821 fps. However, due to resistance from the czar, Fedorov had to make due with the readily available 6.5x50 Arisaka cartridge.

The next Russian attempt at fielding an intermediate cartridge was much more successful. The 7.62x39 M43 cartridge was adopted in 1943 and remained the Soviet standard until replaced by the 5.45x39 M74 cartridge in 1974.

Driving a 123-grain FMJ-BT projectile with a mild steel core at approximately 2,330 fps, it has proven fairly effective. Its strong points include reduced bulk and weight compared to a full-size rifle cartridge, reduced recoil, fairly good penetration through intermediate barriers, low manufacturing costs and sufficient terminal performance at common engagement ranges.

While the 7.62x39 cartridge does many things well, it does nothing outstanding. It is considerably heavier than more modern military cartridges such as the 5.56x45 NATO, 5.45x39 M74 and 5.8x42 Chinese. It has a trajectory similar to a thrown bowling ball. Its recoil is noticeably heavier than modern small bore military cartridges, and "accuracy" and "7.62x39" have never been synonymous. Last, terminal performance of standard M43 steel-core ball has always been lackluster.

For American shooters this cartridge's main attraction has always been its inexpensive price. There was a time when you could purchase 1,000 rounds of 7.62x39 ball for $70.

Unfortunately those days are long gone. Like all other ammunition, the price of 7.62x39 ball has steadily climbed. Today it's often more than $200 per 1,000 rounds.

Despite the spike in prices, the 7.62x39 cartridge remains hugely popular among American shooters. However, those who would like to utilize this intermediate cartridge for self-protection face a lack of modern loads in this caliber. Due to the availability of inexpensive foreign ammunition, domestic manufacturers have largely ignored this round.

To be blunt, AK shooters tend to be the cheapest shooters on the planet. In years past they were interested only in the best deal they could find while leafing through the pages of Shotgun News. So designing a modern dedicated projectile, and developing a suitable load, for this cartridge was not economically viable.

However, the introduction of the 6.8x43 SPC and 6.5x38 Grendel cartridges stirred interest among many shooters for a modern 7.62x39 load. Both of these modern intermediate cartridges offer a substantial step up in terminal performance compared to traditional intermediate military loads.

Cor-Bon came out with a 123-grain Barnes load in its DPX line, but it's very expensive. So what can your typically frugal 7.62x39 shooter do to improve the performance of their ammunition without busting the bank? Well, quite a bit actually if you have some basic reloading equipment and a quantity of steel case ball.
