Chapter 256 Changes to bullets

    "Crack, click." When they returned to the factory, almost all the machines were in motion.

    Qin Baoshan stood in front of a shell punching machine, watching the operation of the machine.

    Before this machine, the Eighth Route Army could only use reloading bullets, that is, recovering the shell casings, cleaning, and refilling the bullets. After all, the quality of the secondary filling bullets is not as good as conventional bullets.  On an automatic rifle, the problem may not be big, but when it is used on an automatic machine gun, due to the irregularity of the shell casing, it is easy to cause jamming.

    If the bolt-action rifle jams, just withdraw it. Anyway, the rate of fire is not high, but if it is a machine gun, it will be a waste of time.

    Therefore, even if he was just starting out, Qin Baoshan filled the bullets when he was in the guerrillas of Lujiao Mountain, and he used them for the 38th cover, and the finished bullets were used for the crooked handle.

    Now, with this stamping machine, our side can finally produce brand new bullets.

    "Actually, we could also make it in the past." At this time, a new worker named Liu Zizhong was operating the machine tool, and while operating it, he introduced it to Qin Baoshan.

    "In the past, we used the manual beating method." Liu Zizhong used to work in other repair shops, and he was transferred here when he obtained a large number of machines and planned to become the largest military factory of the Eighth Route Army.  , now, he is already the operator of this machine.

    In fact, the bullet casing is stamped with brass. The texture of brass is relatively soft, so even if it is beaten by hand, the bullet casing can be pressed out.

    However, under that method, the quality cannot be guaranteed. After all, there are errors in manual manufacturing, and it depends entirely on the operator's own technology.

    "A skilled worker like me can make about 20 in an hour." Liu Zizhong is a middle-aged man in his forties. His two hands are covered with calluses and his face already has wrinkles, but he is still  Smiling: "Now, one can be made in a few seconds!"

    What's the effort? Put the brass and copper wires that have been cut into sections, click it, and one will come out.  Even under the premise of ensuring safety, two or three hundred can be punched out in an hour, and two to three thousand can be made in a day!

    Moreover, the stamped shells have a bright surface without any scratches. They are the best shells. The quality of the copper wires from the little devil is really good!

    "Well, Master Liu, you are right. With this machine, we can make bullets faster." Qin Baoshan said it casually, because now his heart is not on this.

    "However, the batch of copper wires seized last time may only be used until the end of the month. Next, we have to think of other ways." Liu Zizhong continued.

    As an old master, he still has a lot of things to worry about. The raw materials are snatched from devils, and there is always a time when they run out.

    "Next, we still have a lot of copper coins." Qin Baoshan said: "It has been stored for a long time, and we will use copper coins to make it."

    Copper coins?  That's money!  Liu Zizhong sighed with his tongue, "Our men are all copper coins."

    "Yeah, there is no way, we can only do this temporarily, and when our technicians can smelt brass by themselves, the cost can be greatly reduced." Qin Baoshan said: "After all, we want to use copper-clad steel instead  , Technically, it is estimated that it is enough.¡±

    "Copper-clad steel? What is that?" Liu Zizhong was very surprised.

    People in this era have never heard of these things. Qin Baoshan smiled: "It is to use steel to make the shell, but on the outside of the shell, brush a layer of copper."

    The shell case looks simple, just like the one in front of you. It was made on the stamping machine at once, but its requirements are very high. It needs to be filled with propellant, and the warhead and primer must be connected to  Together, it will bear the power of gunpowder gas pressure and firearm automatic machine when launching.

    Therefore, since its birth, the cartridge cases have been made of brass, which is also the best raw material for making cartridge cases. Brass is not easy to rust and has a long storage time, good self-lubrication and thermal conductivity, high ductility, and low probability of fracture and jamming.

    Therefore, the bullets of major countries in the world use brass casings.

    However, brass is expensive.

    Just like casting bronze cannons in ancient times, it was made with money, and brass was used to mint coins. Even now, brass is still very valuable.

    The motherland's brass resources are not rich, so after the founding of the People's Republic of China, copper-clad steel was used to make the shells, which are made of steel and have a layer of brass on the outside.  Of course, the performance is worse, but fortunately, it is cheap.

    ? This requires superb craftsmanship to?Understand, at present, the level of our side here is impossible to be satisfied.

    And this Liu Zizhong, after hearing about it, became curious and was probably thinking about what to do.

    "Well, Master Liu, I have an idea." Qin Baoshan said to Liu Zizhong: "Can you specially produce a batch of bullets with shortened casings for me? Shorten the casings from 57mm to 33mm?"

    Hearing his words, Liu Zizhong immediately withdrew his hand from the punching machine, and looked at Qin Baoshan with strange eyes: "What did you say? Change the bullet?"

    What's this?

    This is an innovation that no one can imagine.

    In China, there are a large number of military factories. Zhang Xueliang's military factory in the north is the most comprehensive, and the Jinsui Army is also good. Lao Jiang's has inherited previous achievements. However, no matter what military factory it is, it is impossible to change the bullets by itself.  !

    The bullet looks small, but the emergence of a bullet requires years of research and development, experimentation and improvement, and finally becomes a standard, just like now, almost all domestic weapons use 7.92mm Mauser  Rifle bullets, this kind of rifle bullets started in 1888, with a round head at that time, and later in 1905, it was changed to a pointed head, which has been used until now.

    Everyone's rifles can be imitated at will, and they can even be invented and created, just like our own Bayi-style rifles, but in terms of bullets, no one dares to move them, so it is not on the same level anymore.

    This Qin Baoshan actually wants to change the bullet?

    Moreover, if you want to change and increase the power, there are still people who believe that you are trying to shorten the shell, or reduce the power. What is the purpose of this?

    Looking at the way the other party opened his eyes wide, Qin Baoshan knew that the other party must be shocked at this time. There is no way, there is no medium-power rifle ammunition in this era!

    "Can it be made?" Qin Baoshan asked.

    "It can be made, but the mold needs to be changed." Liu Zizhong said: "But why is this?" (Remember the website address of this website: www.hlnovel.com
