Chapter 3175

For a long time, the caliber of rifles in various countries was chaotic, and they chose their own standards. It was not until the end of the world war that the 7.62mm rifle became the mainstream with the development of assault rifles. However, due to the large caliber, the problems of recoil and muzzle jump were still difficult to solve.

Therefore, Eagle first put forward the standard of 5.56 mm rifle bullet, which soon became the mainstream caliber in the West.

Then, Xiong Guo also started research and development and chose 5.45mm caliber. For a time, rifles all over the world began to change to small caliber.

With the same carrying weight, small caliber bullets can carry more. Moreover, many battles break out below 200 meters. Therefore, the concept of small caliber is very popular.

On the other hand, small caliber bullets can roll more obviously when they enter the human body, which can better kill the enemy and create more power than large caliber rifles.

Han naturally followed the trend of small caliber. After years of research, it chose 5.8mm. Moreover, following the development trend of rifles in the world, it developed 95 gun families, which can be regarded as entering the sequence of small caliber rifles and supportless rifles.

But then?

After equipping the army, the supportless rifle still brought a lot of trouble to the army, and the army is the most conservative service. After repeated weighing, the 03 gun family came out again. This assault rifle has returned to the structure with butt again, and the 95 rifle is destined to be a flash in the pan.

Just after that, the eagle people found that the small caliber rifle was not enough in the war of the mountain country.

In the war of mountain countries, the fighting distance is very different from previous experience. Due to the mountains and deserts, they often appear in the fighting area of about 500 meters. At this time, their 5.56 mm rifles are powerless.

In fact, the bullet of a rifle can fly far. It's OK for a 5.56 mm bullet to fly 500 meters away. However, 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, it will not produce deformation and fragments, and it can't bring any lethality.

The eagle army suddenly found that they had only 7.62mm squad machine guns on hand and could maintain their lethality. However, it was impossible for the whole infantry squad to use the same equipment. Although the lethality of machine guns was amazing, they also consumed a lot of bullets. An infantry squad could only have one machine gunner, otherwise, their firepower sustainability would be seriously insufficient.

Moreover, what's more, in order to unify the caliber and facilitate supply, many of their squad machine guns also use 5.56 mm caliber. Therefore, where their automatic rifles can't reach, their squad machine guns can't do anything. The eagle soldiers in combat at that time didn't know what it was like to hold the fire stick in their hand, and their opponents, Holding the seemingly backward AKM, you can pour it effortlessly with 7.62mm bullets.

The eagle people finally found that the caliber of 6.8mm is very good. This caliber is between the small caliber and the normal caliber, so it is also called medium caliber. The warhead weighs 7.45g, almost twice the weight of the M855 warhead of 5.56mm. In this way, the killing power at a long distance can be guaranteed. At the same time, the shell length of this bullet is similar to that of the 5.56mm bullet, A normal 30 round magazine of M-16 can hold 28 6.8mm SPC bullets, so the number of bullets carried by infantry will not be greatly reduced. Moreover, even at 600 meters, its residual energy is 40% higher than that of 5.56mm bullets.

Therefore, the voice of 6.8mm rifle bullets is getting higher and higher. However, it is not easy. After all, 5.56mm bullets have been produced for decades and have a large inventory. Although many 7.62mm bullets have been produced before, they can be installed on machine guns after all, but once 6.8mm bullets are fully used, the 5.56mm bullets will be completely discarded, This is a huge waste. Even the rich Eagle country absolutely dare not do so. Later, with the end of the mountain country war, the topic of whether to change the caliber is no longer so popular.

For these reasons, Qin Guan always had some concerns about the caliber of infantry rifles. He did not firmly support 5.8mm or oppose it, but chose to wait.

After all, now the eagle country has begun to fight in the mountain country. Soon, there will be a voice of 6.8mm rifle caliber. At that time, the Han country will not have to take detours.

Anyway, the 7.62mm bullet has been used in China for a long time. It's no problem to change to the 6.8mm caliber. It won't be heavier than the 5.8mm bullet. Everyone is used to the heavy steel gun in his hand.

Don't underestimate rifles. This kind of equipment is characterized by a large number. Therefore, it affects the whole body with one shot. We must be careful.

"What caliber are you going to choose?" Ramses asked Qin Guan. He wanted to deceive the other party. Since you haven't chosen, you might as well use our standard system. In this way, there is a greater possibility of export.

After thinking about it, Qin Guan solemnly replied, "I think 6.8mm caliber is more suitable."

This is not a leak. Even if more countries in the world choose the caliber of 6.8mm, it can promote the change of caliber in Han country and directly transition to the medium caliber of 6.8mm. So, just take this opportunity to deceive each other.

Sure enough, when he heard Qin Guan say 6.8mm, Ramses was stunned: "why?"

This caliber is now nondescript. Only during the world war did some countries adopt this caliber. Now of course, there is such a caliber. It is a special shotgun and a special caliber of precision shooting rifle, which is not popular.

"This is a caliber that we are currently studying in China. We think that although small caliber is a trend, we still like powerful ones." Qin Guan said: "our pursuit of power is endless."

Ramses felt puzzled and always felt that this caliber was neither fish nor fowl.

"I also suggest you study it, even if you first produce some trial products, so that you may have a chance to sell them." Qin Guan said with a smile, "seize this business opportunity, it is a world of heart."

"6.8mm? Greater power?" Ramses carefully tasted this sentence. It is difficult for other manufacturers to touch a new caliber rashly. After all, many manufacturers make guns, but not bullets. They only make guns according to the specified bullets. But for Steyr, these are their strengths. They have this ability.

If there are real business opportunities, whoever gets involved first will take the lead. It's like a supportless rifle. Their Aug can be famous because they come in early.
