Chapter 3175: 6.8 mm diameter

For a long time, the calibers of rifles in various countries were chaotic, and each chose their own standards. Until the end of the world war, the 7.62mm rifle became the mainstream with the development of assault rifles. However, due to the large caliber, the recoil And the muzzle jump problem is still not easy to solve.
Therefore, the Eagle Country first proposed the standard for 5.56mm rifle bullets. This standard soon became the mainstream caliber in the West.
And then, Xiong Guo also started research and development, choosing 5.45mm caliber. For a while, rifles all over the world began to change to smaller calibers.
In the case of the same carrying weight, small-caliber bullets can carry a larger number, and many fighting outbreaks are also less than 200 meters. Therefore, the concept of small-caliber is very popular.
On the other hand, small-caliber bullets can roll more obviously when entering the human body, which can kill the enemy better and create even more power than large-caliber rifles.
Naturally, Han is also following this trend of small-caliber. After years of research, it chose 5.8mm. Moreover, following the trend of world rifle development, the 95 gun family came out, which can be regarded as entering the small-caliber rifle and In the sequence of unsupported rifles.
But what happened later?
After equipping the army, the unsupported rifle still brought a lot of trouble to the army, and the army is the most conservative service. After repeated weighings, the 03 gun family came out again. This assault rifle is back again. It has the structure of the butt, and the 95 rifle is destined to be a flash in the pan.
And just after that, in the war of the Mountain Country, the Eagles discovered that the small-caliber rifles were not enough.
In mountain country wars, the combat distance is very different from previous experience. Because it is mountainous and desert, it often appears in the combat area of ​​about 500 meters. At this time, their 5.56mm rifles are already powerless. .
In fact, the rifle’s bullet can fly very far, 5.56 mm bullets can fly to 500 meters away, but at this time, the speed of the bullet has been reduced to less than 700 meters per second. At this time, even if it can hit The target will not produce deformation and fragments, and it will not bring any lethality.
The Eagle Nation Army suddenly discovered that they had only 7.62mm squad machine guns on hand that could maintain the lethality. However, it was impossible for the entire infantry squad to use the same equipment. Although the machine guns had amazing lethality, they also consumed a lot of bullets. Yes, an infantry squad can only have one machine gunner, otherwise, their firepower will be seriously insufficient.
Moreover, what’s more terrible is that in order to unify the caliber and facilitate the supply, their squad uses machine guns, many of which are also 5.56 mm in caliber. Therefore, their squad’s machine guns cannot do anything where their automatic rifles cannot reach. The Eagle Nation soldiers in a fighting state don't know what it feels like to hold the fire stick in their hands, but their opponent, holding the AKM that looks backward, can use 7.62mm bullets to pour over without any effort.
The Eagles finally discovered that the 6.8 mm caliber is very good. This caliber is between the small caliber and the normal caliber, so it is also called the medium caliber. The warhead weighs 7.45 grams, which is almost twice the weight of the 5.56 mm M855 warhead. , It can ensure the long-range lethality. At the same time, the length of this bullet is similar to 5.56mm bullets. A normal M-16 30-round magazine can hold 28 6.8mm SPC bullets. Therefore, the infantry’s The number of bullets carried will not be greatly reduced, and even at 600 meters, its remaining energy is 40% higher than that of 5.56 mm bullets.
Therefore, the call for 6.8mm rifle bullets is getting higher and higher, but this is not easy. After all, 5.56mm bullets have been produced for decades, and the inventory is large, although the 7.62mm bullets have not been produced before. Less, after all, it can be used on a machine gun, but once the 6.8mm bullet is fully used, the 5.56mm bullet will be completely discarded. This is a huge waste. Even the eagle country with rich wealth would definitely not dare to do so. Later, with the end of the Mountain Country War, the topic of whether to change the calibre became less popular.
For these reasons, Qin Guan always had certain concerns about the caliber of the infantry standard rifle. He did not firmly support or oppose the 5.8mm, but instead chose to wait.
After all, the Eagle Country has already started fighting in the Mountain Country. Soon, there will be calls for a 6.8 mm rifle caliber. When that time comes, Han Country will not have to make detours.
Anyway, the 7.62mm bullets have been used in China for a long time. I switched to the 6.8mm caliber. There is no problem. It will not feel heavier than 5.8mm bullets. Everyone is used to the heavy and heavy steel guns in their hands.
Don't underestimate the rifle. This kind of equipment is characterized by its large quantity. Therefore, it affects the whole body by a single shot and must be cautious.
"What caliber do you plan to choose?" Rams asked Qin Guan, he really wanted to fool the other party. Since you haven't chosen yet, it's better to just use our standard system. In this way, there will be a bigger export. It is possible.
After thinking about it, Qin Guan solemnly replied: "I think the 6.8mm diameter is more appropriate."
This is not a leak, and even if more countries in the world choose the 6.8 mm caliber, it can also promote the replacement of the domestic caliber in Han, and directly transition to the middle caliber of 6.8 mm. So, simply take this opportunity to fool the other party.
Sure enough, when Qin Guan said 6.8 mm, Rams was taken aback: "Why is this?"
This caliber is now nondescript, and only during the World War, certain countries adopted this caliber. Of course, there are also such calibers now. They are special shotguns. The special caliber of precision shooting rifles is not popular.
"This is a caliber that we are currently studying in our country. We think that although small caliber is a trend, we still like powerful ones." Qin Guan said, "Our pursuit of power is endless."
Rams found it inexplicable, and always felt that this caliber was nondescript.
"I also suggest that you study it, even if it is to produce a part of the trial products first, then there may be a chance to sell it." Qin Guan said with a smile: "This business opportunity, grasping, that is a world of heart. "
"6.8 mm? Greater power?" Rams carefully tasted this sentence. For other manufacturers, it is difficult to touch a new caliber. After all, many manufacturers make firearms. , But they are not making bullets, they just make guns in accordance with the required bullets. But for Steyr, these are their strengths, and they have this ability.
If there is a real business opportunity, whoever gets involved first will take the lead. Just like an unsupported rifle, their AUG can be famous because of the early entry.
