Chapter 267 Do it yourself (second update)
"My father is back. They said he should retire. My mother will no longer be alone in Kyoto. But my father is still a little unhappy." Xiaoyun pinched her bangs hard for a while, almost letting her continue to use family methods.

"Just come back, just retire." Liu Hai didn't know what to say when he heard this.

However, Lao Lou's stay on Hong Kong Island in the past few years will also be beneficial to his future development there.

Liu Hai's life returned to normal, and no one associated things thousands of kilometers away with the person in front of him.

In the maintenance department, Liu Hai is making a sniper rifle. The drawings and materials for the sniper rifle have been out for a long time, but it has been delayed for a while because of time constraints.

"Is this the sniper rifle you're talking about?" Sun Aiguo asked, looking at the parts made by Liu Hai and the bullets made by Liu Hai himself.

"Director, I made these. Do you want to find a place to try them?" Liu Hai nodded, and it was time to take them out now.There are only a few months left until October.

"I have to give it a try. Let's go and try it ourselves first." Although Sun Aiguo knew Liu Hai had good stuff, he still felt that a gun wasn't that powerful.

12.7 mm is just the caliber of a machine gun. Sun Aiguo has even fired machine guns. In Sun Aiguo's mind, caliber means everything. No matter how powerful your gun is, it is still a gun.

Liu Hai prepared four types of bullets: ordinary armor-piercing bullets, incendiary bombs, tungsten core armor-piercing bullets, and ordinary bullets.

There are only 20 bullets of one type, all of which are handmade by Liu Hai using equipment in the maintenance department.

The factory's security department often trains at the shooting range, so there is no need to notify them of preparations.

Because the security department has recently been equipped with new short assault rifles, all personnel need to be retrained, and marksmanship is learned with bullets.

When Liu Hai assembled the parts of the sniper rifle at the shooting range, the head of the factory's security department stared like a bull's eye.

The person in charge of the shooting range heard that people from the motorcycle factory were coming to test new guns again and followed him.

I originally saw Liu Hai taking out a lot of parts, and the barrel looked like a machine gun barrel, but I didn't expect that when assembled, it turned out to be a long gun.

"Sniper rifle?" The person in charge of the shooting range looked at Liu Hai and put the scope on the gun. What is this gun for?Just plain and simple.

Liu Hai equipped this gun with an eight-fold scope, and the ten-fold scope was being manufactured. The scopes of different periods, even the same three-fold scope, eight-fold scope, etc., actually had completely different qualities.

Different from previous target shootings, this time a thick steel plate was installed on the target.

"Yes, this is a large-caliber sniper rifle, mainly aimed at light armored targets." Liu Hai spoke more professionally now, and no one would question it.

This time, the targets were set at 200 meters, 400 meters, 800 meters, and 1000 meters.

After the people from the security department arranged the shooting range, Liu Hai took a look at it himself and found that the 1000-meter target was larger.

After Liu Hai carefully inspected them, he nodded with satisfaction. These targets had a steel plate on them, and they were 20 mm steel plates.

"This is an ordinary sniper bullet, mainly used against low-value targets, that is, people." Liu Hai took out a bullet and introduced it to Sun Aiguo.

Sun Aiguo nodded, and then let Liu Hai do the operation.

Of course, Liu Hai would not operate it himself. Instead, he put the sniper rifle on a machine, debugged it, and then loaded the bullet.

Then the group of people stepped aside from Liu Hai and pulled the rope. A switch on the device that fixed the sniper rifle was touched, and the trigger of the sniper rifle was pulled.

With a bang, the bullet flew towards the target 200 meters away.

As expected, the steel plate on the target did not penetrate, but only left deep marks.

Liu Hai took out the chalk and drew a circle, then came over and took out the second type of bullet: "This is an ordinary armor-piercing bullet."

Ordinary armor-piercing bullets directly penetrated 200 mm steel plates at a distance of 20 meters.

The steel plates of motorcycle factories are between ordinary steel plates and armored steel plates.

"This is an armor-piercing incendiary bomb."

With the sound of a gunshot, everyone came behind the target and looked at the wooden board that was still burning after penetrating the steel plate with shock on their faces.

Sun Aiguo looked at the target 1000 meters away and felt that today's things were not simple...

"This kind of bullet is expensive to make, so we won't shoot 200 meters for the time being." Liu Hai said while holding a tungsten core armor-piercing bullet.

This kind of bullet is expensive to make and is not very cost-effective for close range shooting. As for war, basically a sniper may not be able to beat a rifle at 200 meters. After all, the opponent can hit it. The kind of concentrated gun that can be used at dozens of meters is the best. The duel only exists in some movies. The duel between snipers is life or death. There are no fancy movements, such as lifting legs, rolling, jumping. The kind of jumping is for fear of exposing one's body size...

Then there is the distance of 400 meters. Ordinary bullets are obviously less powerful than at 200 meters.

The power of ordinary armor-piercing bombs and armor-piercing incendiary bombs is obviously greatly reduced.

Only then did Liu Hai take out the tungsten core armor-piercing bullet, which easily penetrated the 20 mm thick steel plate.

600 meters, 800 meters, is the stage for tungsten core armor-piercing projectiles.

The person in charge of the shooting range looked shocked. What did it mean to penetrate a 800 mm thick steel plate 20 meters away?
This means that the enemy's machine gun positions and mortar positions are all targets within the distance of this gun.

It may not be easy to hit a person 800 meters away, but it is very simple to hit a machine gun position to hit a lightly armored target or even a mortar position.

If such a bullet hits the mortar shell box, it will directly cause the shell to explode, and the entire mortar position will basically be destroyed.

After the gunshot, the group of people couldn't wait to run to the target 1000 meters away.

Looking at the 20 mm thick steel plate that was penetrated, although it was not an armored steel plate, it still made everyone present take a breath. What does the power of penetrating a 1000 mm thick steel plate, even an ordinary steel plate, from 20 meters away mean?
Sun Aiguo did not ask Liu Hai what was special about the bullet on the spot, and it looked unusual.

When they got to the car, Sun Aiguo couldn't wait to ask: "Xiao Liu, what was the most powerful bullet just now?"

"This is a tungsten core armor-piercing bullet..." Liu Hai explained.

"You write a document here, and then make some more bullets, and I will send them to the ministry for acceptance." In fact, Sun Aiguo wanted to pick it up and shoot it just now, but he did not do that considering the test process.

Once a sniper rifle is produced, it does not mean that it will be tested with real people immediately. It must be tested continuously to see how it can withstand.

How many times can these rifle chambers and barrels be used?
If you use people to test rashly, it may bring bad results, which is what Liu Hai requested.

Liu Hai also wanted to pick up a sniper rifle and shoot a few shots himself, but it was impossible, and Sun Aiguo would not let himself do this.

"This is more powerful than a heavy machine gun." Sun Aiguo could only express it in his own poor language.

Because in Sun Aiguo's impression, the heavy machine gun is considered the most powerful gun.

Liu Hai nodded and murmured in his mind: "If you had seen the power of a 14.5mm machine gun, you would know it. That thing uses 14.5×114 bullets, which is as powerful as a 20mm machine gun."

As soon as Sun Aiguo returned to the factory, the leader of the machine department called. The person in charge of the shooting range had already called to report first. The main reason was that this gun was too abnormal.

When the army leaders heard this, they didn't believe it at first.After repeated assurances from the person in charge of the shooting range and the rumor that someone from the motorcycle factory was here to test the gun, the army leader quickly called the leader of the First Machinery Department.

The leader of the First Machinery Department was also puzzled as to why no one reported to me. He happened to have something to do with Sun Aiguo, so he asked Sun Aiguo to come here.

Sun Aiguo had no choice but to go to the ministry to report on his work.

"Comrade Xiao Liu talked about making a sniper rifle in the first half of last year. At that time, I thought he was making a small-caliber sniper rifle, but I didn't expect that he was making a 12.7 mm sniper rifle. I was shocked when I heard that." Sun Aiguo was sitting there In front of the leader of the First Machinery Department, he said while smoking.

The leaders at this time liked to smoke. In fact, it was because they were used to relieve anxiety during the war years, such as after and before the war.

"You still haven't seen it? A 1000-meter target has penetrated a 20-millimeter-thick steel plate. With this thing, what do the enemy's heavy machine guns and mortars count?" Shen Aiguo said excitedly. Then, he explained in detail what happened during the target practice just now.

When the leader of the First Machinery Department heard this, he said angrily: "You didn't know how to ask me to go and have a look with you."

"Don't I feel confident? I will report on the work immediately after preparing for the test. I have asked Comrade Xiao Liu to prepare the materials for acceptance by the department." Sun Aiguo quickly explained that this is also a normal process.

"This new bullet designed by Comrade Xiao Liu, I personally feel that it can be made into the same artillery shell with greater power." Sun Aiguo also talked about the bullet Liu Hai mentioned.

The leader of the First Machinery Department heard this: "What kind of bullet is it?"

Sun Aiguo gave a brief introduction. After hearing the introduction, the leader of the First Machinery Department nodded and asked people in the department to study it later.

"By the way, you still have to take responsibility for the refrigerated trucks and prepare two refrigerated truck manufacturing workshops with a monthly output of at least 500 units. This is this year's output." The leader of the First Machinery Department said while drinking water.

When Sun Aiguo heard this, he said with some dissatisfaction: "Boss, didn't we agree? Let others produce this thing."

The leader of the First Machinery Department has no choice, because all the units below are calling to report, and the only thing is that we only accept refrigerated trucks from motorcycle factories, otherwise we don’t want them.

The leader was still a little angry and asked why?
The unit below said confidently: If another type of vehicle breaks down, it will be broken. We can repair it ourselves. But if the refrigerated truck breaks down on the road, whose contents are broken?
They also said that if it was not produced by a motorcycle factory, they would rather not have it.

Only then did the leader of the First Machinery Department wake up.In the past, if a truck broke down on the road, it was broken. If you could repair it yourself, you could repair it. If you couldn't repair it, you could just leave it there and go back to find someone.

But the refrigerated truck really broke down on the road and there was no place to repair it. What would happen to the contents inside?
"Old Sun, I simply feel that you are at a loss." Of course, the leader of the First Machinery Department could not tell the truth, and wanted to let Sun Aiguo do it on his own from another aspect.

Sun Aiguo looked at the leader with some confusion, and then the leader explained: "Look, you produced the platform of the refrigerated truck itself, and you produced the core refrigeration equipment. You produced all the most important things, and the supporting equipment." The factory will take it to install a carriage..."

When the leader said this, Sun Aiguo was stunned. It seemed to be the truth. The car was produced by himself, the refrigeration equipment was produced by himself, and other factories just built a carriage?
"This is not the key. You said that if you hand over good equipment and they produce it, there will be problems here and there. Do you think it is a waste?" The leader of the First Machinery Department said again.

"Okay then." Sun Aiguo weighed it up and found that building this refrigerated truck was okay and would bring more benefits to the factory, so he nodded.

In the afternoon, Liu Hai sent away a complete set of information, as well as sample guns and the like. This time the design and manufacturing were all done by Liu Hai. One person was in the maintenance department, and the others were working on compressor equipment for refrigerated trucks in the workshop.

A sniper rifle is nothing. Liu Hai is also planning to develop a 14.5mm heavy machine gun in the future. Of course, this thing will be equipped on an armored vehicle.

The main reason is that for such a large-caliber heavy machine gun, if it is not equipped with an armored vehicle, it will be really tiring to carry bullets manually.

From now on, the armored vehicle will be used as a machine gun fire support. Of course, it can also be equipped with machine guns. As for whether it is tracked or wheeled, we will talk about it later. It can also be amphibious... Ahem, it's really not who Liu Hai wants to target. After all, our vast territory coastline.

Liu Hai is currently focusing on laying out basic areas, that is, coming up with a product to fill the gaps in areas we are lacking, and we will take our time in subsequent upgrades and optimizations.

Of course, this is within the scope of our own capabilities. If we say that we are lacking too many things now, from aircraft to missiles, and then to warships.

The bangs side is measured based on the working condition level here.

"After the centrifuge production is completed, all equipment will be upgraded again." Liu Hai is ready to start with equipment such as machine tools again.

This time, after the upgrade of machine tool equipment, it is CNC machine tools.

"There are still several years to go before the first four-bit microcontroller." Liu Hai remembers that the first 4004 microprocessor chip seemed to be in 1971.

"It's a pity that I'm not proficient in the semiconductor field. It seems that I will find ways to support this industry in the future." Liu Hai doesn't know everything.

In fact, there was enough time to develop chips in the 80s. Why Liu Hai asked Xiaoyun to go to Hong Kong Island was because he wanted to have a sum of funds in his hand that he could use to do whatever he wanted. Liu Hai had no intention of interfering in the government's affairs. Yes, that's asking for death, and there is always a group of people. These people can't do anything for money...
