Starting from the bright sword to engage in military industry

Chapter 230 Chapter 229, the magic reform raises its guns, old readers don't subscribe

Thanks to Hu Changyi's request and the efforts of comrades, the guerrillas have copper plates, and they are brass plates of very good quality, which are just right for making bullet casings.

It took Hu Changyi more than a day to prepare more than 100 kilograms of nitrocellulose, plus some left over from before, and he spent more than a day to make 200 kilograms of single-base propellant.He doesn't know whether the speed is fast or slow, and there is no comparison, so that's it.

Well, this is not the point, the point is that with these, the workers who reload the bullets can reload the bullets as much as they want.

For bullets, there are only four parts: shell case, primer, propellant, and warhead.The shells are ready-made, the primers are stamped and manufactured by themselves, and the warheads?
The warhead production of bullets has already become proficient at the military workshop. Put a few molds there, some for beating the steel core, some for beating the copper shell of the warhead, and then use lead as an adhesive to seal the steel core. Filling into the shell, after shaping, a bullet is formed.

Unlike the devil's plated rifle bullets, the Bing Workshop made the front of the bullet not round or pointed, but hollow-pointed.Hu Changyi did not tell others what effect the hollow point bullet will have after hitting the human body, but told everyone that doing so will save a little copper.

It took more than three days, and the news of Taierzhuang's great victory also spread to the southeast of Shanxi. The troops from all walks of life were excited, and they also gained confidence when facing the enemy.

That's right, Taierzhuang has won a great victory, and the little devil is not invincible, so let's fight!

Hu Changyi is in the military workshop, so he doesn't know too much about the battle on the outside line, but occasionally some transport companies will arrive at Hanjia Village.They came here with applications from various regiments and guerrillas, as well as materials seized on the battlefield and bullet casings they picked up, and they brought news of the battle.

After they told the comrades in the military workshop about the battle situation, Minister Zhang, who came back from inspecting the village from the east, would issue an approval note according to the situation, and they would bring the bullets that had just been reloaded in the military workshop, or the Time to store those grenades back.

I believe that within a day or two, these bullets and grenades will greet the devils.

In this way, it is much more enjoyable than slashing the devil's head with a big knife.

Hu Changyi finished working on the propellant, and the modification of the big gun that he asked for had also been completed, and he also had time to finalize the magically modified big gun.But before that, he still had to focus on the production of custom shotguns.

"These shell casings are well made and ready for production! From now on, our military workshop can be considered to be able to produce bullets by ourselves! Oh, they are so big, they should be called artillery shells!" In a temporarily added courtyard, Hu Changyi looked Starting with a bullet case in his hand, he said very satisfied.

The barrel of the Shaan-made large gun is 41.3mm in diameter and smoothbore.The shell mold that Hu Changyi requested was 41.5, which is not contradictory.

In fact, the outer diameter of the cartridge case is even larger, after all, it has to match the barrel.The larger caliber is actually to give the shell a fixed positioning.Why are some cartridge cases flanged at the bottom?There are also structures such as elastic neck and shoulders?In fact, it matches the mechanical structure of the barrel and the bolt.

These things are very troublesome to say, but because they are compared with the original bullets of Shaanxi-made big guns, it is not troublesome to make them, just follow the gourd painting.Now that you have a qualified cartridge case, add a primer, propellant powder, add steel balls and wooden bullets to seal, and do another wax seal.

Here, what Hu Changyi needs to determine is actually how many grains of black powder or single-base propellant to put in, and how many steel balls to put in the shell.After choosing from various solutions given by the system, Hu Changyi finally chose a standard that he thought was the most suitable.

Therefore, after some modification, the gun can shoot out about 4 2000mm steel balls (1 grains per kilogram), and it can penetrate the devil's cotton coat at a range of 3831 meters and embed about one centimeter in the human body. 150 meters, that is the best killing distance, it will beat people into a sieve.

Well, this is the standard value chosen by Hu Changyi.For the Eighth Route Army, which lacks bullet training and lacks good guns, being able to hit the enemy at a distance of 100 meters is good marksmanship.Especially for those rifles made by the old Hanyang, the bullets will float away after firing tens of meters, or even turn around.

Now, raising the gun can hit a large area of ​​enemies at a distance of 100 meters. How do you think the eight roads will choose?And this does not require marksmanship training, you only need to master how to pull the bolt and how to reload.Hit someone?Where there are more people, the squad leader no longer has to worry about my marksmanship...

Of course, with such a change, these tanks with big guns that want to hit the devils should not even think about it, and even slugs should not be fired anymore, the barrel can't hold it anymore.

However, this gun is absolutely handy for hitting devil trucks at a distance of 100 meters.Especially these days, devils lack steel, and the fenders of some trucks are made of wood. This gun is enough to deal with trucks, and it can even get a good engine.

The main purpose of the previous modifications to the big gun is to reduce the weight, adding a built-in bipod and a separate tripod that can be used as a support.Well, it's similar to the general-purpose machine guns of the MG series.

Carrying the gun, it used to be used by two people, one carrying the barrel and the other aiming the gun, which was very troublesome.Now after Hu Changyi's modification, it is still operated by two people, but the person in front does not need to carry it on his shoulders, and it is good to be the assistant shooter with the tripod and ammunition.

After the modification, the weight of the large gun has changed from the original 14.4 kg to about 10 kg at once, which is 8 catties and 8 taels lighter, and only 0.4 kg heavier than the Czech type.With this weight, the gunner can carry it away alone.

Um, not everyone has the strength of Li Tieniu. This is to consider the physical fitness and strength of ordinary people. After all, this is not for Li Tieniu.

After the modification, the gun length has changed from the original 1588mm to 1314mm. The sawed-off barrel can be used as a grenade projectile tube after being hammered, or transformed into a grenade launch tube, but that is a later story. up.

By the way, after the system-assisted inspection of these big guns brought by the organization, it was found that the steel of the barrels was all high-quality barrel steel imported from abroad in the past, otherwise Hu Changyi would not dare to change it randomly.

In fact, no matter how you change it, the big gun is still an old-fashioned old-fashioned product, but after some modifications, it is more suitable for the battlefield.Well, the most important thing is to turn the previous slug into a fixed shotgun, which is very important.

A slug, no matter how powerful it is, how many bullets can one shot pierce?You have to be able to hit people, it's different if you switch to shotgun.
