The history of rifling is quite long. In fact, it appeared as early as the fifteenth century, and the twenty-seventh 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 because of 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 loading ammunition from the back, directly from the starting point of the barrel, can the rifling play its full role.

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

And it can be produced initially.

How can Zhu Yunxian not be surprised?

You know, the power of rifling on firearms is not ordinary!

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

Da Ming could clearly feel that the bullet flew out slower and more accurately!

Even if it is barely fired, at least once or twice before, the remaining residue of the white powder will clog the muzzle, making it difficult to fire the firearm.

There is also the problem of not loading bullets, and it also avoids the problem of bullets that are too large and cannot be fired.

Ming Dynasty was full of high spirits.

"Leave him alone!"

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

"That's wrong. Although the rifling has been manufactured, it will still be useful if there are unmatched bullets."

Said: "Look at it, Your Majesty! That's enough!"

Taking advantage of the expansion characteristics of metal, gas is injected into the metal to completely seal the matching rifling.

And take a piece of pipe on one side and press it hard upwards.

However, because the rifling unevenness is flat, special bullets cannot be placed and receded naturally. Bullets with small calibers will get stuck by the rifling formed by the negative and positive lines.

Da Mingxi was stunned for a moment.

Xu Miaojin suddenly took out a bullet from his sleeve and pressed the bullet into the barrel of the gun with ease.

After all, it is very difficult for Xiao Ming to just provide firearms to the new army. Jinling Fourteenth Workshop works overtime every day to produce only one hundred thousand firearms.

Shen Mingxuan frowned and looked around with confusion, only to see that the bullet in the barrel seemed to be larger than the caliber of the original barrel.

Focus on stability and let military households naturally become workers.

Because for the time being, someone can solve the problem of loading the rifling of the breech-loading gun.

Inside the barrel, there are flat grooves instead of concave and convex, forming a complex spiral shape, making the bullet more stable.

Bang!

Moreover, the emergence of rifling has taken a step back to increase the strength of the new army.

But when Shen Mingxuan looked from the barrel of the gun.

Everyone would have thought that Xiao Ming’s craftsmen could come up with such a way to solve the practical application problem of rifling!

"Sure enough, Xiao Ming's future lies in the Technology Research and Manufacturing Bureau."

A flat barrel, with or without rifling, would make cleaning and loading bullets easier.

Just waiting for this day, Damingxi felt that it would take a long time.

Shen Mingxuan nodded, I did think so.

Craftsmen in the East are far worse than those in the West!

It was a mistake. The Ming Dynasty once again had the idea of ​​continuing to reduce its army. But after that time, the Ming Dynasty would learn the lessons from the future.

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

Only muskets that are not equipped with rifling can lack such accuracy!

Xu Miaojin even introduced: "Your Majesty is worried that the front end of the bullet you developed that time is not hollow."

It can’t even be said to be far ahead! The West could only make it hundreds of years ago, and today’s Xiao Ming craftsmen can’t solve the things they think of!

He said: "If everyone could stop having such fantastic ideas, even the Jinling Yangtze River Bridge could be completed within next year!"

Exquisite shape.

Daming Yan hurriedly put away his gun, almost hiding the smile on his face.

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

Although the research and development of rifling made Shen Mingxun happy, what really made Damingxian depressed was that I saw the potential of Xiao Ming's craftsmen!

"so bad!"

"At that time, the bullet will be unable to break away from the constraints of the rifling, and can only follow the trajectory of the rifling and retreat! The bullet fired in this way will be slow and accurate!"

"Send the order, I want you to reward the craftsman who came up with that idea!"

"I really want to give it a try." Daming Sui was overjoyed, holding the musket in his hand and pointing it at a stone on the bank of the river.

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

But it's not strong because I'm too vague about the shortcomings of rifling.

And this stone is no more than seven or seven hundred meters away from the Ming Dynasty! If it were replaced with a special firearm, it would be possible to hit it!

Then I hit this stone by the river!

So far, no one has been able to change the rifling to the point where it cannot be equipped for the entire army.

Xu Miaojin suddenly asked.

It cannot be pressed into the barrel easily, otherwise it will be blocked by the rifling.

"Let everyone rush to imitate and contribute to Xiao Ming!"

Only by preventing the bullet from jamming the rifling and firing in the direction of the rifling can the bullet gain better stability and its power will be slightly improved.

Smoke rises!

"The explosion before the gunpowder is ignited will cause the bullet to expand!"

But last moment.

"Your Majesty, do you think you have solved the problem of bullet loading?"

All you need to do is press firmly on the strip to secure it.

High accuracy and high range are the characteristics of firearms only after rifling! Otherwise, with the capabilities of ordinary barrels, the power of bullets would not be that great!

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

If we add the effort of rifling, I'm afraid it will be simpler and more troublesome.

Zhu Yunzhen was slightly confused.

Rather, it is a semi-weak method.

"really?"

Build the Jinling Yangtze River Bridge for Xiao Ming, which is also a miracle!

Xiao Ming's skill in craftsmanship completely exceeded Shen Mingxun's expectations.

That’s not the miracle of the East!

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

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

In the Ming Dynasty, Hexi was self-successful.

Gave me a little surprise!

This will allow Ming Dynasty to boldly use the new army to dismantle the old army and turn the original old army into Xiao Ming's labor force!

Allowing people to better control firearms.

That's all.

Only a muzzle-loading gun can perfectly solve that problem.

Simply a genius among geniuses!

Moreover, it was not until that time that Ming Dynasty discovered that the place where ammunition is loaded and fired inside the barrel is larger than that of abnormal firearms.

"It's true that they made it." A faint joy flashed across Daming Xi's face.

It’s truly a work of art!
Chapter completed!
