477 War Preparation 3
Now everyone wants to test the gun to see how powerful it is, Li You also wants to try it out, anyway, the gunpowder has already been produced, and even the launched projectiles were cast a few days ago. If you want to try it, you can’t Simple, as long as you load the medicine, you can try it right away.
Afterwards, Li You went to the gunpowder workshop and took some gunpowder and fuse. He first inserted the fuse into the hole of the rear cartridge, and then put the gunpowder into the cartridge, using a cast copper warhead that had been prepared a long time ago. Just plug it in. Both cartridges are charged two kilograms. This is specifically used to test the barrel, not a stereotyped cartridge.
Actually shaped cartridges will not contain so much gunpowder. The ratio of black powder to ammunition is one to three. One catty of powder pushes three catties of projectiles. For a gun with a caliber of less than nine centimeters, one catty of powder can be used. It is enough, not to mention this is a rifled gun with a long barrel. It doesn’t really matter how much the cartridge is charged. If you need to reduce or increase the cartridge, you just need to remake a suitable cartridge. Whether it’s OK or not, it depends on the results of the test.
Since the warhead is not round, but a streamlined body similar to the bullet shape, and hollow inside, the weight is naturally not that heavy. Although the gunpowder is not particularly large, the range should not have any effect. Li You doesn't know how far he can go, so he can only wait to test later.
At the corner of the bastion site, Li You asked him to build a stone wall with stone bars. About a hundred meters away, he tied the cannon on a wooden stand. Since there is not much gunpowder, it is estimated that the recoil will not be very large. After aligning, Li You took the Huozhezi and lit the lead. Then he ran away. Although the lead wire was not long, most of his thread medicine was charcoal. He had time to run away. To be honest, the theory is one thing, but the experiment is another. I dare not just stand aside like this.
For rifled guns, the accuracy is relatively high, but whether it can be hit or not is really hard to say, but, again, now it’s all large corps fighting, even if there is no accuracy, it doesn’t matter much. , As long as the shells fall into the crowd.
What's more, what Li You got out was a rear cannon, which has many benefits. Although there are not many medicines, the power is still not bad, and the bullet is changed quickly. You don’t need to consider the temperature of the barrel and the residue of the barrel. You can wait until after a battle is over before you come to clean up.
With a sound of "bang", the cannon moved, but it did not show a particularly strong recoil. It seems that a small amount of medicine is still good. Everyone was shocked. The stone wall that everyone looked at at first had already collapsed. This was indeed very powerful.
This is not over yet. There is one more shot. Li You needs to test the range. He holds the projectile and twists it to the left. The projectile exits the slot and can be taken out easily. Then, he took out another bullet body similar in appearance to the later-generation bullet case and stuffed it into the breech, and after reaching in, he twisted it to the right to complete the replacement.
The last shot was not shot from the back, but the person looking for the warhead found it only four miles away. This distance made Li You very satisfied. Next, Li You checked the body of the gun. There was no problem at all. As long as you change the barrel with a pound of bullet, the recoil will be smaller. The rest is the quasi-equipped with these external things. There are two circular grooves cut out on the barrel. As long as the cannon is mounted on a carrier with a clamping device, the cannon is installed, and the carrier needs to be followed. It is made, anyway, now there are ball bearings, it is not a problem at all to be a cannon, and it is easy to transport. In fact, this artillery is not heavy, only one hundred and twenty catties.
Qiu Chengfu now finally knows why Li You would let him travel so far to learn how to forge a cannon, and he has been doing it all the time. This power is really not comparable to manpower. He stepped forward to Li You and asked: "Patriarch, this cannon is so powerful that I was a little frightened when I looked at it. Could it be used for battlefields?"
"This is indeed used in the battlefield. With him, the enemy will no longer be terrible. Remember, you must not leak it to outsiders, otherwise it will be troublesome."
Qiu Chengfu bowed and said: "Patriarch rest assured, we are all members of the Li family, and we naturally obey the instructions of the patriarch. In addition, the power of this cannon is too powerful, if others learn, this will cause chaos in the world, and the younger ones will order everyone. "
Li You nodded and then said: "Forging a cannon, I will demonstrate to you again. You need to learn how to make all the equipment here. I will give you two sets of cutting tools at that time. You can learn it completely here. They returned with Dong Kui. Next, I will do some other things, so you can learn something."
"Understood, Patriarch, we will study hard."
Today’s business is over, and it’s time to take a good rest. Tomorrow we will have to continue to forge the artillery. After that, Li You will teach them how to complete the cutting. After the teaching, he can let go, and he has to prepare the cannonballs. It is the real lethal thing.
Li You is still a little helpless about this. This is not a cast iron gun. Cast iron bullets cannot be used. Cast iron does not cost much, but the gun barrel can’t stand it. In terms of material selection, he can only choose soft metal. I have considered lead, but in this era, not much is mined, and it is expensive. It is better to use copper. Therefore, for the time being, the only projectile he can use is copper. ァ新ヤ~⑧~1~中文网ωωω.χ~⒏~1zщ.còм
The next thing he has to do is to actually make an explosive projectile, which is not difficult for him. The projectile can be formed by hydraulic mechanical stamping of copper plates, which can make the projectile very thin, and then use a knife to scribe the fragmentation line inside. Open a wire opening at the tail, and finally install the designed explosive body. The pre-installed iron beads and gunpowder of the explosive are simple, and it is rare that it is the fuze of the shell. It takes a bit of brainstorming to ensure that the shell is 100% ignited and exploded.
In the next few days, the workshop was fully operational. Although it was a workshop type, it was also regarded as a factory standardization. It was nothing more than the steel quality of each furnace was different, but this did not affect it. Use, nowadays the most made here is steel pipe.
Nowadays, the mass-produced steel pipes are nearly two centimeters in diameter, less than one centimeter in diameter, and sixty centimeters in length. The selected steel is also low-manganese carbon steel. The process is the same as that of artillery. The projectile body is a pure copper bullet. It is loaded with ammunition, but this is indeed a matchlock gun. There is a groove in the lead part of the cartridge, and the lead just passes the groove. As long as the match rope is a little bit, it can be fired instantly, basically without any delay.
Li You tried the gun. The effective shooting distance is one hundred and fifty meters away. This position is still very powerful. After all, this is a rifled gun. Although the shooting distance of this gun is far more than that, but after all, the gun Its muzzle velocity is not high, no matter how far away it is, it will not be possible to shoot accurately, and the distance visible to the naked eye is already very small, even modern firearms can hardly achieve effective shooting. But that's nothing. You can shoot platoons from a long distance. Anyway, the battles are now in dense formations. (End of this chapter)
