The plan to upgrade the machinery and equipment of the arsenal has been completed, and a total of three lathes and one 10-ton press have been renovated. There was also a machine for mechanically loading bullets with gunpowder. Although far less advanced than the fully automatic and unattended machines of later generations, it has greatly liberated the labor force of the workers.

However, only one machine for the mechanical filling of gunpowder was produced. Although everything was normal during the test, the yield rate of bullets is directly related to the life safety of soldiers on the battlefield, and can even affect the success or failure of a battle. Therefore, Tian Zheng asked to produce one first, and then sample the bullets produced by this machine. Moreover, these products are not directly assembled with troops, but handed over to Tian Zheng to be used as training bullets for the security regiment.

Today is the 24th day of the twelfth month of the solar calendar, and tomorrow is Christmas. Liu Tianxing told Tian Zheng that the imitation of the German Mauser 24-year rifle had been successfully trial-produced. Today is to invite Tian Zheng to do the test in person.

Tian Zheng drove the car he had robbed from Wu Yuanwai in Xuzhou and ran to the shooting range in Sanlidi, east of Liaocheng City. There was already a company of soldiers on duty here. And then there's a bunch of engineers in the arsenal.

Tian Zheng took the gun sent by Liu Tianxing. The length of the gun is 1.11 meters, of which the barrel is 0.6 meters long. The ruler is used to illuminate the door, and the blade type crosshair. The magazine has a capacity of five rounds, and the bridge clamp loading method is adopted. Four rifling wires are engraved in the barrel, and when the bullet is discharged, it rotates forward, which increases stability and accuracy. The design scale has a range of 2 kilometers, and the practical range is 500 meters. The muzzle velocity of the bullet is 810 meters.

Tian Zheng took a look, and it was indeed basically the same as the drawings he had drawn. Even the shape of the round pimple at the tail of the bolt has not changed in the slightest.

Tian Zheng loads, raises the gun, aims, shoots! The whole action is done in one go and is very coherent. The onlookers applauded!

"Bang!"

Pull the bolt.

"Bang!"

……

After five consecutive gunshots, Tian Zheng put down the gun. The flag soldiers here issued flags, and the target reporters at the target at 100 meters, 200 meters, 300 meters, 400 meters, and 500 meters away in the distance reported the rake in turn.

"10 rings!"

"10 rings!"

"10 rings!"

"9 rings!"

"10 rings!"

The five target reporters finished counting the rings in turn, and at this time, everyone present shouted,

"Captain!"

"Captain!"

"Captain!"

……

Tian Zheng pressed his right hand weakly, and the audience fell silent, but everyone's faces were filled with an expression of excitement!

"This gun is good!" Tian Zheng expressed his opinion. Liu Tianxing and his party immediately jumped up excitedly!

"It worked!"

"yes, it worked!"

The engineers and masters of these arsenals were excited to congratulate each other!

No one can describe their mood at this time! They may not have heard of the fame of the German Mauser, or maybe they have heard of it but do not know it too deeply, but this does not prevent them from admiring this new weapon! Because this new gun is much better than the Hanyang-made gun that has been produced before!

Tian Zheng waited until their excitement gradually calmed down, and said, "This gun has basically reached the performance parameters of the design. Next, I have to work hard for everyone to do a specific performance test about this gun! I've got a list of test items here, and you need to follow it strictly! And this gun has a drawback, that is, every time a bullet is fired, there will be a very small amount of gunpowder residue remaining, which leads to the difficulty of pulling the bolt next time! If it is a continuous shot, it will be difficult for a normal person to pull the bolt if he can fire about 30 shots in a row at most! I have some ideas for this problem, and there are two main directions to solve it, the first is about the improvement of the new formula of bullet primer gunpowder. The other is a redesign of the bolt! But this is a research topic! Just think about it in your spare time. It's best to have a harvest, and you don't have to mind if you don't. After all, the Germans have not been able to solve this problem! ”

At this moment, the surrounding engineers looked at each other and smiled. They can also make guns that rival the advanced German rifles!

"Moreover, in every battle, under normal circumstances, a rifle rarely has a chance to fire thirty shots in a row!"

The parameter test table left by Tian Zheng greatly shocked the group of engineers and gun testers.

For example, the relationship between muzzle velocity and the charge of the bullet, the effective range of the bullet's trajectory in the absence of wind, the angle of deviation and lethality to each distance, the penetration of the bullet at the range of each target, the relationship between the ballistics and the customs, the range of the bullet in water, and so on. The exhaustive options make these engineers tired and happy. For each option, they strictly followed Tian Zheng's requirements and made no less than 300 tests. There was no rest overnight, and more than 100 lamps of various kinds were erected on the shooting range. There are fifty high-power bulbs among them. Concerned about the power of the power plant, I didn't dare to connect too many light bulbs, but the rest was lit by oversized kerosene lamps and torches. The entire shooting range was as bright as daylight.

Tian Zheng didn't know that they were actually testing overnight. That night, he returned to the headquarters of the security regiment early, holding a big red apple in his hand, but he was in a daze there.

"It's Christmas Eve! Tomorrow is Christmas! If it hadn't been for this sudden crossing, I would have been entertaining myself with my colleagues at the institute! A large group of old men chatted and farted together, and watched various news and entertainment programs in the army through the military network special line. Or drive the two warriors in the institute and take people to the bubble bar in the city below the mountain at night. No matter how drunk you are, you can wake up the next morning with a gift on the bedside table and a simple but exquisite breakfast. Thinking of the major Wang Mei who had always secretly liked him but didn't dare to confess, Tian Zheng somehow had a slight sense of happiness in his heart. Did I fall in love with her? But I've always thought she was my sister! Tian Zheng shook his head a little confused! Perhaps, only when you lose all this, you can know that the Tao is precious, and only when you no longer have it, can you discover your heart!

I don't know what happened to her? I was in the middle of the explosion when it exploded, so she shouldn't have been doing anything, right? Thinking of this, Tian Zheng's desperate desire to go back to the mountains to take a look calmed down again.

Since I've come to this world, I must do something! Otherwise, I didn't come for nothing! Wang Mei, don't worry, I'll accept you when I go back!

But can I go back?

Tian Zheng asked himself this in his heart.

Perhaps, the answer lies in the southwest mountains, and it will not be revealed until the day when you go to check it yourself.
