In the machining workshop, the sound of metal hitting metal echoed one after another. The seven most senior and most skilled workers naturally took on the responsibility of the basic production unit of manual custom-loaded ammunition to run the entire production line.
At the beginning, as they had not been exposed to this manual stamping production method, everyone was inevitably a little unfamiliar. Under Zhuang Qianding’s careful instruction, the seven workers quickly became familiar with each other as they gained skills and experience from hammering to hammering. .
The second 7.92mm fixed-loading bullet took eight minutes to complete the entire manufacturing process, and the third one took two minutes, which was the same as the first bullet manufactured by Zhuang Qianding.
The higher the experience and craftsmanship, the faster the production speed.
By the time the fifth bullet was fired, the production speed of the seven-person production line had risen to a higher level, and the time taken for a single bullet had been shortened to 5 minutes and 30 seconds.
The sixth one, 5 minutes and 20 seconds.
The seventh one, 5 minutes and 10 seconds.
The eighth one, 4 minutes and 55 seconds.
As the five-minute mark was exceeded, the seven workers, who were already sweating profusely in the sweltering heat, worked even more passionately and energetically. Everyone showed no signs of slacking off and all operated at the highest efficiency.
They know very well what they are doing. This is to produce the most precious new bullets for the troops!
Since the Long March, the army has been in extremely short supply of ammunition and has been completely unable to meet demand. Due to the lack of relevant technology, they have to resort to reloading ammunition. This makes the original ammunition very precious and is generally only used by sharpshooters and veterans.
Recruits who use reloaded bullets often have inaccurate shots on the battlefield, leading to battle defeats.
I have to say that this is a shame for military workers.
Nowadays, it is possible to produce new custom-loaded ammunition with this set of tools. What a precious opportunity is this?
The seven people did not dare to slack off at all.
Lin Wan stood next to the production line, holding a pencil in hand, constantly recording the production time of each bullet and the technical essentials of the production process. These production data are extremely precious, and can be summarized as a set of production standards suitable for manual custom-loaded bullets.
She clearly remembered what Yu Hua said, standards are the most important.
"This kind of production line can be replicated. I suggest that the Military Industry Bureau's reloading bullet production line be stopped and all the collected brass cartridge cases be remelted and rolled into brass plates. In addition, the mining and smelting of Jingbian Copper Mine should be accelerated. The supply of copper materials must keep pace with the On the market, one ton of copper can produce 1.6 tons of brass. Calculating the mass of 11 grams of cartridge cases, jackets and primers, it is equivalent to approximately 145,000 rounds of bullets." Zhuang Qianding looked at the steel and brass plates that were being consumed in the production line and took back Looking at it, he handed the five bullets that had passed the quality inspection into the hands of Chen Kang beside him, and reminded him.
The manual custom-loading ammunition production line has been set up. The next step is to train personnel, manufacture equipment, replicate the production line, and exchange manpower for output.
However, the core issue must not be ignored, and that is the supply of raw materials.
Once this kind of manual custom-loaded ammunition production line is laid out and reaches a certain scale, the supply of copper must be guaranteed.
Moreover, when it is possible to produce fixed-loading ammunition, it is meaningless to continue to reload bullets. Instead of doing this, it is better to remelt the cartridge case and roll the brass plate.
"I'll make arrangements right away. The Jingbian Copper Mine has started mining and smelting. Brass will be delivered soon. Don't worry." Chen Kang took the five brand new bullets and knew its importance without hesitation. He responded that he had already made up his mind to stop the production of reloaded bullets immediately.
"Director Chen, do you have a gun? I haven't shot a gun since I returned to China. I had a great time today and tested the bullet performance by the way." Zhuang Qianding continued to ask.
"Of course." Chen Kang nodded.
The bullet production in the workshop continued. Zhuang Qianding and Chen Kang left and found a piece of wasteland to the north of the arsenal. They planned to clear the surrounding area for a temporary shooting range. Then they found an 80% new Hanyang-made rifle from the guard soldiers and used it. Do bullet testing.
The content of the entire bullet test is simple. It is mainly to detect whether the bullet has problems such as jamming and ejection, as well as basic parameters such as whether the bullet can be fired normally and shooting accuracy. Ballistic tests such as extremely professional bullet muzzle velocity measurement cannot be carried out due to limited conditions.
Zhuangqianding stands in the center of the shooting range. There are three gun targets in total, fifty meters, one hundred meters, and two hundred meters.
Four guards belonging to the headquarters security regiment were standing around. Their sharp eyes spotted the five bullets in Zhuang Qianding's hand. These bullets looked very new, with a bright yellow surface and extremely smooth surface. They were newer than the bullets he carried. many.
Looks extremely tempting.
"Squad leader, these bullets look so new..." As the owner of the original gun for bullet testing, the young guard couldn't help but said to the squad leader beside him.
"Keep quiet." The monitor signaled to shut up and not violate discipline. Even so, his eyes were fixed on the bullet in Professor Zhuang's hand.
"I will only hit fifty meters, leaving one hundred meters and two hundred meters to you, let's experience it together." Zhuang Qianding held Hanyang Zao while loading five rounds of bullets with Liushugou manufacturing labels into the funnel magazine. Said to Chen Kang and several guards around him.
Upon hearing these words, the guard squad leader and the three guards suddenly brightened up.
"As you please." Chen Kang smiled.
Complete loading and pull the big bolt.
Zhuang Qianding held up the Hanyang-made gun with both hands, showing the most standard gun-holding posture. He aimed the dark muzzle at the fifty-meter gun target, locked the target, and pulled the trigger.
The whole process is done in one go and takes two seconds.
While studying in the United States, Zhuang Qianding was often exposed to firearms, whether they were shotguns or revolvers, including Springfield rifles currently in service in the U.S. Army.
"Bang!" The firing pin fires the primer, and the primer explodes and ignites countless nitrocellulose particles in the cartridge chamber. The metal warhead with a real bullet diameter of 8.2 mm rotates at high speed, is embedded in the 7.92 mm barrel, and rotates at high speed under the action of four riflings, achieving a nearly Perfect interference fit.
In an instant, the entire circular metal warhead shot out at a muzzle velocity of 640 meters per second, spanning a short distance of fifty meters, and accurately hit the middle of the bullseye.
Hit the bullseye with one shot from fifty meters.
Seeing this scene, Chen Kang and the four guards were a little surprised. They didn't expect Zhuang Qianding's marksmanship to be so good.
From a linguistic point of view, fifty meters is a very short distance. From a practical point of view, it is already difficult to shoot with a mechanical target fifty meters away.
After looking at the gun target, Zhuang Qianding withdrew his gaze and pulled back the bolt of the gun with his right hand. The yellow bullet shell then exited the gun chamber, and a faint smell of gunpowder smoke filled the air.
The entire ejection process is easy and without any hindrance.
Carefully observing the leaky magazine and the internal conditions of the gun chamber, there was no abnormality. Zhuang Qianding nodded with satisfaction: "There are currently no problems with jamming or difficulty in ejecting the shell. The accuracy of the bullet is good. Director Chen, come and try it."
After finishing his words, he handed the Hanyang-made sword in his hand to Chen Kang.
"Okay." Chen Kang nodded, took the rifle, cocked the bolt and aimed at the 100-meter target, his eyes narrowed.
"boom!"
A few seconds later, the clear and loud sound of gunfire spread throughout Liushugou. The high-speed spinning metal bullet flew along the predetermined trajectory and accurately hit the center of the 100-meter gun target.
After shooting, Chen Kang pulled the bolt of the gun and the cartridge case was ejected. Looking at the golden cartridge case, his eyes were full of satisfaction and comfort.
No matter how you look at it, no matter how pleasing it is.
After two shots, the sound of gunfire attracted workers around the arsenal, who gathered here to watch curiously.
"How do you feel?" Zhuang Qianding came up and asked about the customer's experience.
"Satisfied, very satisfied. It's better than the original ammunition we used." Chen Kang praised repeatedly.
Zhuang Qianding nodded: "Continue to test and see how effective the 200-meter target is and whether the accuracy can be maintained."
After hearing these words, Chen Kang did not object, and then handed the rifle to the original owner: "Xiao Zhou, you are the sharpshooter of the guard regiment. You shoot the 200-meter target. There are three bullets left."
"Yes!" Guard Zhou Rui, who had been waiting for a long time, quickly stepped forward and took over his Hanyang-made product with a face full of joy.
Despite his young age, with this Hanyang-made gun in his hand, he has already set a shooting record of twenty enemies. He is one of the three sharpshooters in the headquarters security group. If it were not for his excellent marksmanship, he would not be able to serve as Professor Zhuang's personal guard. .
Under the gaze of everyone, guard Zhou Rui looked confidently at the 200-meter gun target. Holding a familiar rifle in his right hand, his sharp eyes like an eagle locked the center of the gun target through the gap in the mechanical sight.
"Bang! Bang! Bang!" Three gunshots rang out one after another, accurately hitting the straw gun target 200 meters away, with three bullet holes evenly distributed in the center.
After Zhou Rui finished shooting, Zhuang Qianding and Chen Kang went to the 200-meter gun target to check the bullet holes.
"The accuracy of firing hand-loaded ammunition is about 4.5 MOA. I remember that the shooting accuracy of the Hanyang Type 88 rifle is 4 MOA. Considering the wear of the barrel rifling and the production quality of the original gun, this accuracy is already very good. Overall, it is very good. Generally speaking, there have been no problems such as jamming of manual custom-loaded bullets for the time being, and the performance is still very good. Director Chen, what is the shooting accuracy of reloaded bullets?" Zhuang Qianding looked at the three shooting bullet holes and drew a circle with the center. After a simple calculation, the shooting accuracy of this Hanyang-made hand-loaded ammunition was determined, and he commented.
4.5MOA, which is 4.5 arc minutes, means that at a distance of 100 meters, bullets will be evenly distributed in a circle with a diameter of about 13 centimeters.
This shooting accuracy is definitely far inferior to bolt-action rifles equipped in various countries around the world. After all, the average accuracy per 100 meters is as high as 3MOA, and some guns can even reach 2.5MOA, but it is much better than the reloading bullets used by the Red Army.
"I haven't calculated it. Basically, if it exceeds 200 meters, it will be inaccurate." Chen Kang was a little embarrassed. They had never calculated this kind of shooting accuracy parameter that required mathematical calculation.
"That's it for the time being. The shooting accuracy of the Hanyang-made rifle is 4 MOA, and the shooting accuracy of the Type 38 Arisaka rifle is about 2.5 MOA. There is a big gap between the two. We need to quickly imitate the official rifle to shorten the gap in accuracy. ." Zhuang Qianding sighed.
The shooting accuracy of a formal rifle at 100 meters is about 3MOA. Although it is not as good as the Type 38 rifle, at least there is no generational difference in accuracy.
Yes, generation difference.
Hanyang-made rifles are still lingering around, but the Type 38 rifle has broken three and entered the 2-3MOA 100-meter accuracy range. This is an irreparable gap.
"God's Coming"
The bullet test came to an end. Soon, the test results were handed over to Chen Kang in written form. Chen Kang then went to the cave dwelling to report the situation in person, carrying a report on the manual loading of the bullets and the test results.
…
Moscow, suburbs.
As the world's top radio research institution, the Soviet Academy of Communications Sciences is located in a house with a classical temperament, close to the Moskva River. Standing on the third floor, you can overlook the Red Square building in the city center.
In summer, the climate in Moscow is warm and comfortable, without the coldness of winter.
Inside the Academy of Communications Sciences, there is a statue of Alexander Stepanovich Popov, the father of radio. In the hearts of countless Soviet people, the father of radio in the world is not Marconi, but forever. Popov.
For this reason, there is a statue of Popov in the Academy of Communications Sciences to commemorate Popov’s great contribution in the field of radio.
The gate of the Academy of Sciences.
A group of Soviet radio experts gathered here. Looking around, any one of them would be a top-notch scholar who would be astonishing. And they have only one purpose here today - to see them off.
Among the crowd was a man with an oriental face, wearing glasses and a suit. His gentle manners blended with the temperament of an elegant scholar. This man was the only foreign professor in the entire Academy of Communications Sciences.
"Li, I'm sorry that I can't study electromagnetic waves with you. From the dean's point of view, I don't want you to go back, but from a personal point of view, I support you going back to help your motherland." Dean Ivanov looked at him with both eyes. Li Qiang said slowly with reluctance in his eyes.
Li Qiang, who comes from Eastern China, has been ranked among the top radio experts in the Soviet Union and has his own place in the field of communications.
If it weren't for the request of his superiors, he really wouldn't let Li Qiang go back, firstly because of Li Qiang's talent and strength, and secondly because of Li Qiang's future.
Staying in the Soviet Union, Li Qiang will have a very good platform to gain access to the most cutting-edge and advanced science and technology in the world.
Unfortunately, a war broke out in Li Qiang's motherland, and the Japanese were invading China. Ivanov must agree to Li Qiang's request to return to his country, even though he was reluctant to give up.
"Thank you for your support, and thank you for your continued help and dedication. I have no choice but to return to China." Li Qiang knew what returning to China meant, but he had no regrets. He turned his back to the door and faced the Academy of Communications Sciences with his face exposed. Smile freely and nod in thanks.
"Li, goodbye, take care along the way." Ivanov took a deep breath, stepped forward, and gently hugged Li Qiang.
"Dean, professors, goodbye." Li Qiang and Dean Ivanov hugged each other, and then naturally let go, saying goodbye to the other six top radio experts who were professors.
After saying that, he turned around and left the Academy of Communications Sciences and got into the car parked at the door.
Next, he will take a train to St. Petersburg and take a ship back to his country. This is a journey of 20,000 kilometers, passing through the European and African continents.
Return home.
Go back to help the motherland that was invaded by Japan.
Li Qiang stared at the Moscow scenery outside the car window. He knew that he might not come back for more than ten years after leaving.
Goodbye, Moscow.
