I'm only seven years old, Lao Zhu, you let me supervise the country?

Chapter 350 Good news!New results from the Bureau of Technology Research and Manufacturing!

Rifling has a long history. In fact, it appeared as early as the fifteenth century, and the 27th year of Hongwu was actually at the end of the fourteenth century.

The fifteenth century was only a few years away.

Therefore, rifling is actually not complicated for Ming craftsmen.

However, it was not until the nineteenth century that rifling was truly applied in actual combat.

This is due to the disadvantages of muzzle-loading guns. When loading ammunition from the front, it is impossible to make the bullets match the rifling, which is equivalent to nothing.

Only by loading from the rear, directly from the starting point of the barrel, can the rifling be used to its maximum effect.

But now, Xu Miaojin told him that Ming craftsmen had figured out how to make rifling.

And it can be produced initially.

How can Zhu Yunzhen not be surprised?
You know, rifling is not a great addition to the power of firearms!
High accuracy and high range are the characteristics of firearms only after rifling!Otherwise, with the capabilities of an ordinary gun barrel, the power of the bullet would simply not be that great!

"really?"

Zhu Yunzhen was slightly confused.

But Xu Miaojin quickly took a box from his subordinates, containing a brand-new spear.

Exquisite styling.

Zhu Yunzhen's hands felt very smooth, but upon closer inspection, he could feel the obvious frosting, which increased the friction on his hands.

Allowing people to better control firearms.

On the surface, there is not much difference between this gun except that it looks more refined.

But when Zhu Yunzhen looked from the barrel of the gun.

Inside the barrel, there are uneven grooves in a simple spiral shape, which can make the bullet more stable.

Among them, the concave part is called the Yin line, and the convex part is called the Yang line.

Only by allowing the bullet to clamp the rifling exactly and follow the direction of the rifling can the bullet gain better stability and its power will be greatly improved.

However, due to the uneven rifling, ordinary bullets cannot be placed in it. Bullets of the original caliber will be stuck by the rifling formed by the negative and positive lines.

Making loading extremely difficult.

"It's true that you made it happen." A faint joy flashed across Zhu Yunzhen's face.

But it is not strong, because he is too aware of the disadvantages of rifling.

It is precisely this shortcoming that has caused rifling to fall into silence for a long time and can only be reduced to a supporting role.

Because no one can solve the problem of loading the rifling of the front-loading gun for the time being.

Only a breech-loading gun can perfectly solve this problem.

So Zhu Yunzhen was just happy for the breakthrough of the Technology Research and Manufacturing Bureau. As for the rifling... Zhu Yunzhen could only say that it happened as it happened.

Let's wait and see who can improve the rifling to the point where it can be equipped with the entire army.

But waiting for that day, Zhu Yunzhen felt that it would take a long time.

After all, it is very difficult for the current Da Ming Dynasty to provide firearms to the new army. Jinling Shibafang works overtime every day and can only produce less than [-] firearms.

If you add the effort of rifling, I'm afraid it will be more complicated and time-consuming.

"Your Highness, you think we haven't solved the problem of bullet loading?"

Xu Miaojin suddenly asked.

Zhu Yunxuan nodded, he indeed thought so.

"Yes, although the rifling has been manufactured, it is still useless without matching bullets."

Whether it is the loading of gunpowder or the loading of bullets, it is a big problem.

Even if you can barely fire it, after at most one or two times, the remaining residue of black powder will clog the muzzle, making it difficult to fire the firearm.

It's not as good as a flat barrel with no rifling, but it makes cleaning and loading bullets easier.

But the next moment.

Xu Miaojin suddenly took out a bullet from his sleeve and pressed the bullet into the barrel of the gun easily.And he took the pipe on one side and pressed it down hard.

Said: "Your Highness, look! This is enough!"

Zhu Yunxuan frowned and looked around with confusion, only to see that the bullet in the barrel seemed to be smaller in caliber than the original barrel.

It can be easily pressed into the barrel without being hindered by the rifling.

Moreover, Zhu Yunxuan discovered at this time that the place inside the barrel where ammunition is loaded and fired is smaller than that of normal firearms.

All it takes is a firm press on the strip to hold it in place.

Not only that.

Xu Miaojin even introduced: "Your Highness, don't worry, the rear end of the bullet we developed this time is partially hollow."

"The explosion caused by the ignition of the gunpowder will cause the bullet to expand!"

"At that time, the bullet will not be able to break away from the constraints of the rifling, and can only follow the trajectory of the rifling! The bullet fired in this way will be fast and accurate!"

Zhu Yunxuan couldn't help being stunned for a moment.

The skilled craftsmen of the Ming Dynasty completely exceeded Zhu Yunxuan's expectations.

Gave him a big surprise!

No one would have thought that the craftsmen of the Ming Dynasty could come up with such a way to solve the practical application problem of rifling!

It's really ingenious!
Utilizing the expansion characteristics of metal, gas is injected into the metal to completely seal the matching rifling.

There is no problem of loading bullets, and the problem of bullets that are too small to be fired is avoided.

Simply a genius among geniuses!

"Then Gudang really wants to give it a try." Zhu Yunxuan was overjoyed. He took the musket in his hand and pointed it at a stone on the riverside.

bang!
Smoke is everywhere!

Zhu Yunzhen could clearly feel that the bullet flew out faster and more accurately!
Then hit the stone by the river!
And that stone is a full 500 meters away from Zhu Yunxuan!If it were a normal firearm, it would be impossible to hit it!
Only a musket equipped with rifling can have such accuracy!

"Great!"

Zhu Yunxuan was overjoyed.

Although the development of rifling made Zhu Yunxian happy, what really made Zhu Yunxian happy was that he saw the potential of Ming craftsmen!

The craftsmen of the East are far better than those of the West!

It can even be said to be far ahead!It would take hundreds of years for the West to make it, but today's Ming craftsmen can already solve what they think of!

This is the miracle of the East!

Moreover, the emergence of rifling further enhanced the strength of the new army.

Let Zhu Yunxuan be more bold to use the new army to dismantle the old army and transform the original old army into the labor of the Ming Dynasty!
Build this Jinling Yangtze River Bridge, which is also a miracle, for the Ming Dynasty!

Yes, Zhu Yunxian had the idea of ​​continuing to reduce the army again, but this time, Zhu Yunxian would learn from the previous lessons.

Focus on stability and allow military households to naturally become laborers.

Rather than a semi-forced approach.

Zhu Yunzhen slowly put away the gun, and the smile on his face could hardly be hidden.

"Sure enough, the future of Ming Dynasty cannot be separated from the Technology Research and Manufacturing Bureau."

"I can't live without you!"

"Send the order and I will reward the craftsman who came up with this idea!"

"Let everyone rush to imitate and contribute to the Ming Dynasty!"

Zhu Yunxuan was in high spirits.

Said: "If everyone can have such a wonderful idea, the Jinling Yangtze River Bridge can be completed within next year!"

"I hope that within three years, a bridge spanning the north and south and spanning the natural dangers of the Yangtze River will be built here!"
