Chapter 296 The Eve of Tranquility (First update, please subscribe)
Smokeless gunpowder is an extremely simple technology!

What is the simplest smokeless gunpowder?
It's "celluloid"!

That is collodion.This material, which should have been invented in 1869 in history, was "invented" by Shin Kong Film Company as early as 1864.In fact, this kind of material is not complicated, but by adding camphor to nitrocellulose, it becomes a kind of material with good flexibility, hard and not brittle.

In the past five years, "celluloid" has been widely used not only in the film industry, but also in other industries. Huafu Chemical uses celluloid to produce plastic products such as fake ivory and billiard balls.Later, boxes, buttons, rulers, table tennis balls and spectacle frames were made of celluloid.

As for the propellants... In another world, film film was used to make propellant in large quantities in the base areas behind enemy lines during the Anti-Japanese War, and the film film at that time was made of celluloid!

Since celluloid film can be used as gun propellant in the enemy's rear base areas, Nanhua can also use "celluloid" to make propellant!At least this plan is very feasible!

After this idea came to his mind, Zhu Xianhai took out a pencil and drew the shape of a bullet on the paper.

"Let the arsenal try to produce a new type of bullet. It should be pointed, bottomless, and caliber. It should be around 7 mm for the time being. As for the length of the shell, 50 mm is enough. For the propellant, use "celluloid" particles... ..."

Standing on the shoulders of giants, Zhu Xianhai didn't mind giving a direct reminder, and even skipped the round bullet and used the pointed bullet instead. In fact, the reason why the 9mm rifle bullet performs so well is because it uses a semi-pointed bullet.

""Celluloid" particles? Can it replace gunpowder? With such a small caliber, is it powerful enough?"

Faced with Sun Mingyue's question, Zhu Xianhai said.

"Can you, is it enough? I'll know after the test. Okay, let's connect with the arsenal. The purchase of Type 70 rifles will be temporarily suspended. Wait for the new ammunition, um..."

After thinking about it, Zhu Xianhai said.

"If there is a temporary problem with the propellant, you can make a batch of black ammunition first, but the caliber of the bullet must be reduced,"

As the director of the Military Industry Department, Sun Mingyue was not only a Chinese gold mine worker, but also the first batch of firearms engineers trained by Nanhua. This is why he became the Director of the Military Industry Department. As soon as we got back to the Ordnance Department, we immediately summoned the engineers,
"That's what the boss told me."

Sun Mingyue said directly.

"The commander-in-chief's request is being fulfilled no matter what, so I don't want to hear your opinions, I just want to ask if you can do it!"

"It's no problem to do it..."

Holding his glasses frame, Wang Shiwei took a look at the sketch drawn by the commander. He just came back from the United States last year. During his study in the United States, he had practiced in many weapon factories including Winchester Company. He was an expert in light weapons. expert.

"Whether celluloid can be used as a propellant is still unclear. Even if it can be used as a propellant, whether it can be stored for a long time is also a problem. These need to be fully tested, but before that we can make a backup plan."

"back up plan?"

Under the gaze of others, Wang Shiwei grinned awkwardly, the black-rimmed glasses on his face reflected the light above his head, and his eyes behind the lenses were shining brightly.He pushed his glasses up the bridge of his nose.

"It seems that the commander-in-chief is focusing on new types of ammunition. The issue of propellant powder can be postponed for the time being. Let's produce new types of bullets first. Well, in fact, the bottomless ammunition designed by the commander-in-chief is more suitable for Type 70 rifles. For the magazine, there will be some feeding problems due to the bottom edge of the magazine, and the removal of the bottom edge can overcome this problem. This design is definitely a stroke of genius.”

This is not a compliment, but telling the truth, and then Wang Shiwei said again.

"We can first design a bullet that meets the general's basic requirements, with a caliber of about 7mm and a pointed bullet. What if we use black powder as the propellant?"

"Use black powder? Is this your plan?"

Sun Mingyue asked,
"Will this plan work?"

"Try it and you'll know. It's okay to have a smaller caliber. As long as the muzzle velocity is sufficient, the power is always guaranteed. Besides, you can also make some fuss about the warhead."

Speaking of this, Wang Shi couldn't help laughing, as if he was talking about something ridiculous.

The so-called making some fuss about the bullets, in fact, some people in the army have been doing this all the time. For example, the bullets of 9mm rifle bullets are worn out by armor. When the bullets hit the target, they will deform and expand, and their power will definitely double.It can be used for reference.

"I think in this way, the new type of bullets can be manufactured in the shortest time, so that it will not affect the reloading of the troops. After all, if you change the bullets, you only need to simply adjust the production tools in the factory."

"Um……"

After a moment of pondering, Sun Mingyue said.

"There is a great need for troops to change their costumes now, I think we should follow your method first!"

No one knows what this simple decision means, but what is certain is that the replacement of the security forces was delayed for almost two months, and the 7.7mm Type 70 rifle was issued to the army two months later, while For reasons of prudence and safety, the new bullet uses black powder that looks outdated. In order to meet the requirements for muzzle velocity, the arsenal stuffed a full 50.8 grams of black powder into the 5.4 mm long shell case, which also makes its muzzle velocity Reached an astonishing 760 meters per second.

The newly designed warhead took into account the lack of stop effect of bullets with smaller calibers, so Wang Shiwei, the chief designer, ingeniously designed the structure of the front paper and the rear lead, so that the center of gravity of the warhead is at the rear, and it flips violently after hitting the target to increase the lethality.

Of course, this new type of black powder bullet will eventually be replaced by a new type of smokeless powder bullet, but thanks to Wang Shiwei's suggestion, the security team's replacement was not delayed for long.

Almost at the same time when the security team began to change their outfits, the Paraguay War in the north reached the most critical moment. Although the war hundreds of kilometers away seemed to have no effect on Nan Hua, even the students in Nan Hua School The students are also very clear that the expansion of immigrants in the Shandong area, that is, the Pampas prairie, is entirely due to the fact that the Argentine military was involved in the Paraguay War and was unable to go east. In the past two years, while building the railway, immigrant farms were set up at the same time.

The expansion of Nanhua on the prairie on the north bank of the North River also directly caused the tension between Nanhua and Argentina to the extreme...
