Chapter 1510: The caliber of rifle bullets

Up to now, Han's steel bullet technology has also developed to a mature technology.
For example, the bullet case is a painted steel bullet case. The material is cold drawn steel. The ductility is better but not as good as copper. The bullet is mainly steel, but there is a layer of copper wire wound on the outside of the bullet. This is mainly due to the better ductility of copper. Steel is better, which can better protect the rifling in the barrel.
So, what if the opposite is true?
Not to mention, as long as the copper layer on the outside of the warhead is reduced, that is enough. In this way, when the bullet is out of the barrel, the resistance is too large, and the risk of exploding the chamber will be greatly increased. Exploding the chamber constantly, that scene can definitely make people laugh.
"Yes, let's take a multi-pronged approach. We will work out these plans for them, even if we don't make money, we will do it."
Refurbishing with stocked guns can save part of it, but for bullets, this improved white elephant country-specific bullet does not save costs. It is only when I am happy that I want to cheat you.
Everyone's faces are very happy, and of course they have not discussed it.
"Next, let's start making them. It doesn't have to be all of these bullets. If there are some standard bullets, the other party will not pay attention." Qin Guan said.
Another advantage is that not only Han, but Xiong also have steel-shelled bullets. After all, they are cheap. Therefore, even if they are exported to Baixiang, there will be problems in the end, and only Boris can do it himself. It's hard to argue, it has nothing to do with yourself.
This matter was discussed and decided. Everyone was very interested. Director Gao continued to say to Qin Guan: "Mr. Qin, what do you think of our current Type 81 rifle?"
Factory 2296 is the first domestic light weapons manufacturer, which is why it can undertake the heavy responsibility of producing Type 81 rifles.
Although it is only the design office of the factory, not the design unit of the Type 81 rifle, they have thoroughly understood the overall structure of the Type 81 during the trial production process.
The reason for studying the Type 81 gun family is to replace the Type 56 semi-automatic rifles, Type 56 submachine guns and Type 56 light machine guns being equipped with a squad gun family. After all, the Western world has adopted assault rifles as the main force of the infantry squad.
After all, there is no gun family and no system. It still uses 1956-style 7.62×39mm bullets.
In terms of appearance, it is not much different from the AK47 series, and even laymen can’t tell it. In fact, it already has some of its own characteristics.
For example, the open drum is a new invention. Moreover, the development trend of multi-purpose guns, serialization of gun family, and generalization of ammunition greatly facilitates training, use and maintenance, and not only strengthens the combat effectiveness of combat units, but also Exchange of firearms and enhanced firepower provide conditions.
This weapon was only produced in 1983, and it is still the latest.
However, everyone also knows that it is only a transitional weapon. Now, the development trend in the world has begun to be small-caliber. In 1978, China has officially decided to use a 5.8mm small-caliber automatic rifle in the future.
Now, to ask Qin Guan to give some opinions on this rifle, Qin Guan still can’t mention it, because there is a specialization in the art industry. Qin Guan used to be a military fan. His favorite is aircraft, artillery and tanks. His research on light weapons, really It's not very professional.
However, one thing Qin Guan knew was that the small caliber of the automatic rifle was definitely a pit.
"Our Bayi rifle is our rifle with reasonable design and moderate performance. I think it's good except that it is a bit heavy." Qin Guan said: "In the future, we will use new materials and new processes. By reducing its weight, this rifle can even become our mainstream rifle for decades to come."
"I'm sorry, President Qin, you probably don't know that our rifle is only a transitional model. Now, the country is preparing to use the 5.8mm caliber as the next-generation standard rifle." Director Gao said to Qin Guan.
"I think this is inappropriate." Qin Guan said. I don't know anything else. Qin Guan still has knowledge of small-caliber rifles. If it is appropriate, why later generations, that is, before 2020, including Eagle Country. Is the caliber of the next-generation rifle from 6.5 mm to 6.8 mm?
Now, after hearing what Qin Guan said, everyone was immediately curious: "Mr. Qin, you mean that our choice of 5.8 mm is not appropriate. Should we have the same caliber with the West and adopt a 5.56 mm caliber?"
Qin Guan continued to shook his head: "Whether it is 5.8.5.56 or 5.45, it is not appropriate. A small-caliber rifle is not appropriate at all."
The small caliber is one pit, and the unsupported rifle is another pit. Look at Han, no matter how good the 95-type rifle is blown, didn't the later 03-type rifle return to its normal structure?
Went around in a circle, and finally came back, the rifle is fortunate to say, the big deal is scrapped and rebuilt, what about the bullet? Once a new caliber is changed and so many bullets are produced, it is finally found that the caliber selection is not appropriate, which is a huge waste.
Now, the country has to catch up with the trend and adopt small-caliber rifles. Qin Guan decided to intervene. Don't make detours and directly set the caliber between 6.5 and 6.8. This is the kingly way.
The development of rifle caliber is a major event related to a country or even a military group. After the World War, under the intervention of the Eagle State, the Western world chose 7.62×51 mm rifle bullets as NATO standard bullets, which are called full-scale bullets. Powerful bullets.
Xiong Guo insisted on taking the road of intermediate bullets, namely 7.62×39mm bullets, and introduced the classic AK47 rifle.
But soon, Eagle Country once again led the mainstream and introduced the M16, a 5.56 mm caliber rifle, which fully demonstrated the advantages of small caliber in the Monkey Country War. At the same time, Xiong Guo quietly introduced the 5.45mm AK74 rifle.
In this way, the two camps began to change their outfits. The West unified the 5.56 mm caliber, and the Xiong State faction unified the 5.45 mm caliber.
Where is Han? Han has not caught up yet.
There is no need to rush at all. Think about the helplessness of Eagle Country’s M16 fighting in the Mountain Country, and you know that power is the most important thing.
Eagle Country single-handedly led the trend of small-caliber light weapons, but then overthrew the small-caliber with another hand and began to make 6.5mm rifles.
Now, since I’m here, I’ll do it all in one step. Qin watched everyone and said,
I think our rifle should be between 6.5 mm and 6.8 mm. Choose a suitable caliber, a small caliber rifle. There is no future."
The caliber Qin Guan said is definitely not a small caliber. Generally speaking, the caliber below 6 mm is considered a small caliber.
