"The production of bolt-action rifles is indeed simple and saves materials."
Zhu Han picked up Xiao Xiaoyuan's 38 poses and explained with gestures:
"The three most critical things about a rifle."
"Barrel, locking structure, firing structure."
"Compared with bolt-action rifles, the semi-automatic firing structure has changed a lot but is acceptable."
"The barrels are all the same."
"It has a more complex bolt and receiver, as well as an additional gas tube and recoil spring."
"The processing is indeed more difficult and more materials are used."
"but……"
Everyone is waiting for this but.
Everyone knows semi-automatic rifles are better.
Especially during this period, half of them were used by the Eighth Route Army.
Let’s just talk about the earliest discovered shooting in a group of three.
In order to shoot accurately, the machine gun has to fire three bursts.
Each of the three of them fired one shot, and the three of them aimed separately.
Like a machine gun, but more accurate than a machine gun.
Anyway, the machine gun requires two shooters and one auxiliary shooter. If you add the ammunition handler, it will be three.
The three-person rifle team didn't look too bloated.
If they cooperate well and load the bullets separately, the bullets fired will not break.
Suppress a point if necessary.
When not needed, the three of them split up to cover on three sides.
Just ask the enemy if you are afraid?
This is only the most basic usage.
How else could the soldiers say that five or six and a half are better than machine guns?
But what Zhao Sizhe said is right.
The reality is here, if it cannot be produced or the output is low, no matter how good the weapon is, it can only be hoped for.
Not practical.
So they wanted to push Zhu Han directly to the ground. Stop laying the groundwork and talk about the rest!
Zhu Han said: I just like to see you helpless when you see me unhappy.
"Have you calculated the speed difference between different production lines?"
This time it was Zhao Sizhe's turn to be confused.
When he was interning in the United States, he was an intern at the Browning Firearms Manufacturing Factory.
Although it can be said to be the world's first-class ordnance factory.
But no matter how powerful it is, it cannot escape the fact that it is a company.
Their production line must be matched with the order, and they always produce as many parts as the guns required.
In a situation like the current Shitouqiao Village Arsenal where all the production lines are running at full power, he really has no idea.
"Our gun action is milled according to size by millers."
"Our gun barrels are carved by workers using hand-cranked rifling machines."
"Oh, the rifling is the rifling. Even though it's called such an unfortunate name, it actually has nothing to do with the boring machine."
"While workers are cutting out a gun and carving out a barrel, dozens or even hundreds of steel pipes have been produced on the steel pipe production line."
"The spring production line also squeezed out dozens of recoil springs."
"The work of assembling the firearms will be done directly by the soldiers responsible for security."
"Since what restricts us is the production speed of bolts and barrels, why don't we make better rifles in the same time?"
Okay, now the commanders and fighters are comfortable.
How about saying Zhu Han is a treasure?
When we were still in Xiaojiazizi’s mood, we were already studying the issue of time in a higher dimension.
“But the materials used do have to be deducted.”
Zhu Han seemed to know what everyone was thinking.
"It's just that you didn't button it in the right place."
"The place where you really need to calculate the materials is..."
At this time, Zhu Han had led everyone to a huge warehouse.
He took out the key and opened the warehouse door.
As the wooden door, which was almost two people high, was slowly pushed open.
The scenes inside come into view bit by bit...
"bullet."
bullet!
Neatly stacked bullet boxes like a mountain, each box filled with bullets.
"Oh my God!"
"Someone slap me quickly to see if I'm dreaming."
"I've never seen so many bullets in my life."
"My dear, did you rob the Devil's Palace?"
Looking at the warehouse that was almost filled with ammunition, the brains of everyone present had short-circuited.
Before that, if someone said there were twenty or thirty boxes stored here, all of them would be very happy.
But if they hear that there are forty or fifty boxes of bullets here, these officers and soldiers will most likely kick out the person who reported the news.
When you brag, you don’t know how to brag reasonably, do you treat people like fools?
After all, for the current Eighth Route Army, all the bullets in a regular regiment may not be able to fill 5 boxes.
But what is before them now is no less than 1,000 boxes.
Mr. Liu forced himself to move forward little by little with trembling hands.
Looking at the bullets lying in the packaging in an orderly manner but densely packed, I was stunned.
"how did you do it?"
Now Zhao Sizhe no longer had the arrogance he had just now.
At this time, he was finally like everyone else, his mind went blank.
He couldn't figure out how Zhu Han used that little raw material to produce so many bullets.
“Originally, I used copper-clad steel.”
Zhu Han looked at the stunned people and continued his hard-core science popularization.
"Copper is a good thing. Red copper (also known as purple copper) - that is, pure copper, is even a metal lubricant itself. Unfortunately, it is too soft."
"To make a bullet casing, you have to mix zinc into it to make brass, thereby increasing its hardness."
"And copper-clad steel uses red copper as an anti-rust layer and metal lubricant."
"Based on the plated bullets used in Type 38, one bullet contains approximately 11.5 grams of brass."
"Based on 95% copper and 5% zinc, a plated bullet can extract up to less than 11 grams of red copper."
"To make a short steel bullet, internally coded M43, based on 10% copper coating, a total of 0.9 grams of red copper is needed for the warhead and cartridge case."
"This is still too wasteful, and you won't get many bullets out of it."
The commanders and fighters present were all numb.
One ghost bullet can be exchanged for 12 short steel bullets, which is very small.
Should my math teacher be shot, or should our Chinese teacher have a fight?
Brigadier Chen, on the other hand, expressed his emotional stability.
Did you see that?
This is Zhu's unique magical arithmetic.
"Fortunately, as we develop, the demand for steel is increasing."
"The greater the production of steel, the greater the demand for coke."
"The more coke is produced, the more coal tar is produced as a by-product."
Just when everyone was confused by a lot of unfamiliar terms, Zhu Han finally said the result.
"So I asked the chemical factory to use coal tar as raw material to produce phenolic resin."
"Using phenolic resin as a base material to make anti-rust lubricating paint and then make painted steel."
"In this way, the most copper-consuming cartridge case can be made directly from painted steel, without consuming precious copper resources at all."
"So, for an M43 bullet with a painted steel shell, the theoretical copper amount came to 0.08 grams (10% warhead armor, 10% copper coating), which finally reached a level that I accepted."
"How much!???"×N
Enlightenment! Everyone is enlightened!
Emotions are not what Zhu Han said deliberately to make people angry.
People are afraid that we will get too excited about the past.
According to his calculation, doesn't it mean that one Japanese bullet can be exchanged for more than 150 short steel bullets?
Let’s say it’s less, let’s get 130 instead!
what does that mean?
It means that 15,600 rounds of steel short bullets are enough to kill a Japanese soldier!
It's earned!
It's earned!
Damn it, after so many years of fighting, this is the first time I know that I can still do this when buying and selling bullets.
"There are 1.36 million rounds of ammunition here, most of which were produced in the past month and a half."
"With the investment of large-scale roller presses and stamping machines, two more production lines were built some time ago, and currently eight bullet production lines have been put into production."
"Based on 12 production hours per day, each production line can produce about 5,000 rounds of bullets a day. Although the output is small, it is better than nothing..."
"Okay, okay, okay..."
At this time, Mr. Liu, who was already in tears, completely lost his usual composure.
How could he not be excited?
You know, the Eighth Route Army just entered Jin and achieved the world-renowned Pingxingguan victory.
As the main force and strongest force of the Eighth Route Army at that time, the 115th Division had only about 200,000 rounds of ammunition before the start of the war.
Martyrs who sacrificed their lives, have you seen it?
We've made it through the Eighth Route Army!
"Are these bullets rust-proof? Are they corrosion-resistant? Are they easy to store long-term?"
Zhao Sihan still refused to give up.
But this time, Zhu Han didn't need to speak, Zhu Han's bodyguard Li Dayou answered him directly.
"No problem, Comrade Zhao Sihan."
"Director Zhu starts from the first batch of bullets and takes out some for testing in extreme environments every day."
"Facts have proven that although the storage time of these steel-cased bullets in a humid environment is a little shorter than that of copper-cased bullets, they are within the acceptable range. If properly maintained, they can fully meet the requirements for long-term storage."
This is already the last piece of the puzzle to measure the quality of an ammunition.
Zhao Sihan nodded reluctantly: "It seems that you have indeed come up with a usable ammunition."
In fact, he didn't have any bad intentions from beginning to end.
It's just that Zhu Han's plan was too radical and completely unacceptable to him.
"What about the gun? Even with such a large output of bullets, how many guns can you make? When can soldiers use this gun?"
"Currently, the monthly output is 300 pieces..."
