Wizard: I Brought the Wrong System - Chapter 381

Yarrow is going to make bullets first.

Although bullets are notorious and difficult to make, they are actually not complicated in principle.

Analyze the process of bullet excitation.

After the primer (or detonator) is ignited by impact, the flame is transmitted to the propellant through the fire guide hole, and the propellant deflagrates rapidly to generate high-pressure gas, which pushes the uppermost solid warhead.

The primer (or detonator) is the fuse, the case is half of the barrel, the propellant is placed in the case, and a solid bullet is plugged on it.

—Exactly the same as the firing mode of the soil artillery!

A bullet is basically composed of four parts: warhead, shell case, propellant, primer (or detonator).

The best choice for a cartridge case is brass.

The choice of warheads is much wider. The common ones are copper, iron, lead, less common silver, gold, and the legendary ice, glass, and ceramics.

Considering the cost performance, here Yarrow still chooses brass as the raw material.

The propellant can be directly granulated sugar gunpowder.

The primer is divided into two parts, one is the internal fire material, which needs to be detonated when it is hit, and nitroglycerin can be used here.

In addition, the external wrapping material can also be made of brass.

Brass is soft, ductile, and strong, so most bullets are made of brass.

The warhead is a solid piece of brass. You can make a copper rod first, then cut it off one by one, and process it into a shuttle shape one by one.

Two small holes are reserved at the lower end of the cartridge case for ignition, and a groove is left at the base, which is the reserved position for the primer.

The primer can be divided into two types according to the structure, the Berdan primer (berdan) and the Boxer primer (boxer).

The Berdan-style burner is integrated with the primer, and the Boxer-style burner is integrated with the cartridge case.

The fire platform is the impact point of the gunpowder in the primer after the firing pin strikes the bullet. It can work together with the deformed primer shell, similar to the flint of a flintlock, which can “squeeze” the primer gunpowder to ignite.

The effects of the two fire stands are not much different. Yarrow chose the Boxer-style primer, which is a raised dot in the middle of the groove of the shell base, because the primer of this kind of fire stand is easier to make. Convenience.

The final primer is a small button-sized bowl. After the nitroglycerin is placed, you can cover it with a thin layer of button lid.

If you want to do good things, you must sharpen your tools.

Make the template tool in advance, and the bullets made are of the same size, so there will be no problems when firing.

Just like the fire platform is slightly larger than the groove under the shell, so that it can be stuck with the toughness of the metal itself.

For the same reason, the bullet is also 0.2-0.3 mm thicker than the barrel.

If the precision is not enough.

If the warhead is too large, it will cause jamming and bombing.

If the warhead is too small, the airtightness is not enough, and the high-pressure gas will be squeezed out from the edge gap, which will damage the kinetic energy and reduce the lethality of the bullet.

Therefore, the most important tool is a manual press, which is not complicated, just a large vise borrowed from the principle of leverage, but requires sufficient precision.

As long as a copper tube of appropriate length is heated and put in, a large vise is tightened with brute force, and then a shell case can be successfully produced by hot melting and mold closing.

These tools made by Yarrow are made of self-refined steel, which is not strong enough. After a few times of use, the stamping die of the bullet case will be slightly deformed, so it needs to be constantly adjusted and repaired.

Time passes unconsciously.

…

The rising sun broke through the thick dark clouds and sprinkled warmth on the broken earth.

Facing the golden sunshine, the people in the ruins looked at the surrounding ruins in confusion as if they had just woken up from a dream.

“What happened?”

“Oh! My head hurts!”

“My hand! Why is my hand gone!”

“What happened last night? Why were so many people injured?”

“I’m so tired, I feel like my body has been hollowed out.”

…

Before the frantic noise subsided, an even louder noise broke out.

The harsh sound wakes up the busy Yarrow.

He glanced up at the wooden window, and the soft light hit his face, making him squint slightly.

“It’s dawn.”

The green shoots sprouting on the wooden window tremble slightly in the soft warm wind, and through the lazy light, the mottled little dust is playing and playing.

In the mild sunshine, it seemed like a rich and sweet wine was added, and the lingering biting cold instantly melted away.

Unknowingly, Yarrow closed his eyes.

The pain in his head gradually weakened, as if he had unloaded a heavy burden, the refreshing feeling made him drunk without drinking.

When he came back to his senses, Yarrow couldn’t help laughing wryly when he saw dozens of shiny golden bullets on the table.

“You haven’t even made guns, and you haven’t conducted actual combat tests, so you’ve already made so many?”

However, this also shows that all the production steps have been sorted out by Yarrow.

If necessary, Yarrow can directly take out these utensils and let servants or recruit other people to make them.

Of course, a better way is to directly design a fully automatic production line.

Just as Yarrow was thinking about these issues and tidying up the room, there was a sudden knock on the door outside the house.

“Master Arrow, are you done?”

Lord Clare?

What is he here for?

Although Yarrow was puzzled, he quickly put all the bullets into the space ring, then turned around and opened the door.

The military uniform on Baron Claire’s body was still not removed, his face was cold, his eyes were sharp, and there was a hostility all over his body:

“Lord Yarrow, I’m sorry to disturb you, I have something I want to ask you.”

Baron Clare’s sentiments were not directed at Yarrow, since he did not wear them and, still,

Coincidentally, Yarrow also has a lot of news to tell him.

Although Yarrow is also involved, he will not be arrogant and take everything on himself.

After all, the protagonist of this incident is the County.

At the same time, the earldom is not a fat sheep that is completely slaughtered.

They also have a large number of people, have the Scarlow Fortress that can withstand the attack of an empire, have their own army, and have formal knights that can rival intermediate apprentices.

Thinking of that Red Llanelli who plotted against him~www.mtlnovel.com~ Yarrow’s eyes flickered slightly, he glanced around, and then said:

“What do you want to know?”

“Lord Yarrow, do you have any clues about Ying Xiao?” Baron Claire asked in a deep voice.

Yarrow: “The insider, your personal bodyguard, Miles, didn’t you explain?”

“Last night, he died inexplicably.”

“Inexplicable?” Arrow thought thoughtfully.

Baron Claire’s face became even more ugly: “Yes, the whole body has turned into blood!”

blood?

Isn’t it the same after the blood apprentice who betrayed the Fernando family died?

Wait… Clare’s bodyguard, Miles, who did he obey?
