Origin of this round can be traced back to 1944, during World War II, in the Soviet Union, when the Soviets were in quest of a multipurpose cartridge that could be used in different sorts of weapons to simplify the process during war. It was in the view of countering the US who had someweapons that could use similar round efficiently. Some of the platforms they had in mind included, SKS, AK-47, and RPD among others. Further minor developments occurred throughout 20thcentury, and it continued to be Soviet standard cartridge until the 1970s.
On the contrary, while 7.62x39 was developed as a military caliber, the .308 was introduced a sporting round in 1952 but originated during WW 1. It was an army weapon T65 and machine gun cartridge that was commercially modified. In 1932, it was rejected because a better alternative that could offer better performance was found but then later revived during WW II to find a way of equipping NATO militaries with single rifle and cartridge.
The 308 has been embraced by many countries albeit in different rifles. Presently, it is regarded as one of the big game calibers in the industry used by various types of shooters. Apparently, most of the manufacturers produce this cartridge for purposes of sporting and hunting activities.
If you want to get best result regarding comparing the ballistics of two different calibers, it’s only fair if you consider choosing cartridges of the same brand that probably use matching weapons. This way, you come to understand that values are inclined to alterations from varying manufacturers and accuracy can only be achieved by carrying out the tests repeatedly with other brands.
7.62x39 and .308 have different ballistics. In this case, the former is a transitional cartridge while the latter is a full power cartridge that has relatively heavy shells and high muzzle speed. Preferably, .308 is ideal for long range power. The .308 also seems to be comparatively heavy than the 7.62x39.
Ballistically, 7.62x39 is suitable at CQB/HD since it tends to lose force at 16” barrel. 308 in comparison to 7.62x39 is remarkable t most of the things provided that you use an 18+” barrel. Nevertheless, it depends on the manufacturers where some produce the latter that have a considerable weight though it should be noted that the lighter cartridges compared to .380 from reputable brands are more efficient.
The essence of this is that the caliber for each of 7.62x39 and .308 are designed to aim short and long trails. It also suggests that muzzle velocities and bullet energies are also different in both of these calibers.
The bullet in a 7.62x39 has a diameter of .312, which can also imply that the cartridge is less powerful than .308. The length of the case for .308 is about 51mm while that of 7.62x39 is 39mm. The .308 also safe and when you observant you shall realize that it is stamped on the barrel.
One main similarity between these two cartridges is that they have the necessary power for halting any kind of undertaking that you would wish to bring down. They both have sturdy bullet energy with the ability to deliver more than 1000 pounds pressure.
The .380 seemingly is far-reaching compared to 7.62x39,but it does not essentially show that it is a better option to choose between the two.
Power and range
In terms ofpower, .308 is regarded as one of the highly prolific snipers/DMR calibers. 7.62x39 works better with relatively longer barrels in terms of achieving ideal accuracy at range. Nonetheless, it does not make logic walking with a longer barrel since it does not substantially benefit from the additional length. Actually, the extra 4” will not make any significant difference rather than maneuverability.
The .308, on the other hand, is more accurate, and this is attributed to the fact that it has nicer iron sights compared to the 7.62x39. However, it should be noted that it was not developed with accuracy in mind but rather reliability and dependability. 7.62x39 shoots efficiently between the range of 400-600 meters, and at times it can shoot beyond that.
In general, the .380 is largely superior when used in shooting long range compared to the 7.62x39.
This is another essential thing that you need to know how in regards to comparing these two calibers. The 7.62x39 is manufactured in abundance in most of the former USSR block. Presently, the cost is becoming seemingly large because of the difference in components and quantity of the cartridge. Both 7.62x39 and .308 come with different components, which on paper appear to be minor bit importantly, enough to substantiate the variance in cost. Gunpowder and primers that are used in manufacturing the guns are relatively costly and dangerous thus affecting the difference in pricing.
However, 7.62x39 is more economical that .308 because the latter is more of picky with the powder. In most cases, you also tend to incur additional costs because you need to move the .308 from AR platform to an AR-10.
In terms of reloading, the cost is somewhat same. However, the .308 seems to be more popular than the 7.62x39 when it comes to usage, which simply means that many people own it compared to the 7.62x39.
The good thing with both of these calibers is that they are readily available in many of the ammo stores. It, therefore, means that if you choose either, you will have less time looking for them in major shops dealing with these items. However, if perhaps you reside in the countryside that has few penetrable areas, you should consider going for .308 between the two. The main reason for this is because with .308 you are always assured of getting it any specific time given that most of the ammo manufacturers, especially in the US tend to produce it in large quantity.
At the end of it all, your particular choice will heavily depend on the needs you wish to utilize the gun in. Ordinarily, you can decide to buy a gun for home safety, others for hunting and sporting among others. Some are large while other provide amazing concealability, which means that they would be ideal to carry along for personal security.

But as it has been outlined in the article, if you are seeking a powerful caliber that can shoot in the long range you better go for .308 given that it has all it takes to give you the best results. 7.62x39, on the other hand, is also ideal for users with relativelysmallbudget; it is easy to use and also offer accuracy.
