I'm sure of the prosperous age of Kangxi and Qianlong!

Chapter 412 Rifled Gun and Jiahe Xiangrui
Be careful.

Old man Li brought two craftsmen to the meeting, and also brought two firecrackers.

"I see your Majesty!"

Old Man Li had obviously cleaned up today and put on a brand new official uniform. Even the two craftsmen had tidied up in advance.

The emperor does like officials to do practical things, but he cannot go to see the emperor in dirty clothes every day. This would be really ignorant.

Zhu Yijiong smiled and said: "No courtesy. Did you tell me earlier that the new fire gun has been improved?"

Old Man Li replied: "The improvement has been completed. I have outlined the rifling in the inner chamber of the fire blunderbuss according to your Majesty's instructions. What I have brought here are the two best new fire blunderbuss after the improvements made by the Ordnance Bureau."

Zhu Yijiong was shocked, and quickly asked Old Man Li to bring over the two muskets, and looked at the muzzle of one of the guns. The interior was indeed covered with thread-like rifling.

This is indeed a rifled gun!

Old Man Li also explained: "After our testing, the hit rate of all new fire guns with outlined rifling is generally better than that of old fire cannons. Different rifling outlines and different density will affect the improvement of hit rate. This one in your Majesty's hand , it is the rifling thread with the highest hit rate that we have achieved through constant trial and error.”

Both flintlocks and matchlocks are traditional smoothbore guns (as are shotguns). After the bullet exits the barrel, the strong impact will cause the bullet trajectory to be out of control, and then scatter, greatly reducing accuracy.

Rifled guns are different, because the existence of rifling can provide the bullet with its own rotation force when it comes out of the barrel, thereby keeping it on a fixed track.

The better and more rifling hooks there are, the stronger the rotation force will be and the more stable the bullet trajectory will be.

Zhu Yijiong was very happy: "Li Qing did a good job. I wonder what the output of this rifled gun is?"

Old Man Li was a little embarrassed: "Nowadays, rifled guns basically rely on manual rifling by craftsmen. Although we have adopted double barrel rifling, which improves efficiency, it still requires experienced craftsmen. It is difficult for ordinary apprentices to be competent, so the output is not high. .A craftsman can now only make two or three rifled guns at most a day, while the Nanjing Ordnance Bureau has only a dozen craftsmen capable of fulfilling this responsibility."

The Ordnance Bureau has long adopted assembly line production, and the output of both firearms and artillery has been greatly improved.An experienced craftsman can only make up to three rifled guns a day. This is due to the special method adopted by the Ordnance Bureau, that is, reusing two barrels, rifling the thin barrel, and then inserting the thick barrel.

Because the thinner the barrel, the less difficult it is to hook up the rifling. This is also the original method of making guns by the Red Army in later generations.

However, even so, the huge Nanjing Ordnance Bureau's single-day output of rifled guns was only thirty.

It seems that we still have to rely on the steam engine from Huang Wu. Not to mention starting the industrial revolution, at least we must first develop the rifling of industrial lathes.

Although the rifling of this kind of industrial lathe hook has a lower success rate, it is more efficient than manual work.

Zhu Yijiong nodded slightly: "Thirty guns a day, almost a thousand in a month, and you can teach some smart apprentices while rifling, and then set up awards. As long as you can learn rifling, you can be promoted to a formal craftsman. This rifling When the guns are produced, they will be distributed to the dragoons first, and after the dragoons are equipped, they will be distributed to the various arms and gun battalions."

"Old minister, I obey." Old Man Li responded with cupped hands.

As the ace army unit of this era, the dragoons must still have resources.

It will take at least a few years until these rifled guns can be installed in the entire army, and even if they are installed, the formations will have to be retrained.

Zhu Yijiong asked again: "By the way, does Li Qing have any way to improve the problem of the gun exploding and misfiring?"

Old Man Li shook his head: "I have tried various methods, but the problem of misfire of the flintlock gun is still difficult to solve. Please give me some more time."

It is really difficult to reduce the misfire rate of a flintlock gun that uses flint as the firing device. Basically, it can only rely on technological breakthroughs.

Zhu Yijiong nodded: "Li Qing, don't be anxious. I just asked casually. Take your time with everything. Going too far is not enough."

"Thank you for your strength, Your Majesty." Old Man Li cupped his hands and said, "However, although the problem of misfiring is difficult for me to solve, I have some ideas when it comes to exploding the barrel of a firecracker. I have found that when a firecracker explodes, it is often caused by bullets and a firecracker. Caused by the mismatch of the bore. In this case, the gun bore is difficult to solve, so you can start with the bullets. I have trial-produced a batch of new bullets. These bullets are hollow inside and have a smaller caliber, so they can easily enter the gun bore. When the gunpowder is fired Finally, the bullet will be enlarged by the gunpowder, so it really doesn’t explode.”

Okay, this is the hollow point bullet.No one may have heard of hollow-point bullets, but everyone knows about its advanced product, the Mini bullet.

Moreover, when the effect is similar, the cost of hollow-point bullets is also lower than that of Mini bullets. Although it is still higher than traditional bullets, it can significantly solve the problem of gun blasting.

As soon as Zhu Yijiong heard it, he could tell that it used the principle of thermal expansion and contraction.

This old man Li is a talent!
Zhu Yijiong commended Old Man Li and rewarded the two accompanying craftsmen.These two craftsmen are both good at rifling, and they made the two rifled guns by hand.

Although it is impossible to award a title, it is still very generous to give some gold and silver to land and increase salary.

From the perspective of the officials, the emperor was obviously too biased in terms of his attitude towards the craftsmen.Especially for Huang Wufenghou, many officials sent memorials to tactfully persuade him afterwards.

Unfortunately, the emperor didn't listen at all.

……

The Nanjing Ordnance Bureau began to officially produce rifled guns and hollow-point bullets, which mainly relied on manual rubbing by craftsmen, and the technical productivity was there.

Zhu Yijiong asked Huang Wu about the progress of the steam engine, and asked if the steam engine could be connected to a mechanical lathe, and then the steam engine could be used to mechanically rifle and stamp bullets.

This was considered the emperor's mission. Huang Wu retreated thoughtfully.

a few days later.

"Your Majesty, local officials have reported auspiciousness!"

"Auspicious? What auspicious?"

Zhu Yijiong was stunned for a moment, then took a look at the so-called auspicious box.

I saw an ear of rice lying in the brocade box, and when I picked it up and took a closer look, I saw that it was still one rice with five ears.

A rice with two ears is a good harvest, and a rice with five ears is even more rare.

Since ancient times, the birth of Jiahe has been a sign of auspiciousness. One of Sun Quan's reign names was the Jiahe reign.

In another time and space, in the second year of Yongzheng's reign, Jiahe was discovered in the fields. It was still one rice with four ears. In the second year, one rice with nine ears was even found.

You don't need to guess to know that it is man-made, but it should be found from somewhere, and then lied that it was discovered by Emperor Zutian.

Yongzheng liked auspiciousness, but his father Kangxi, who hated auspiciousness, were two extremes.

Zhu Yijiong only glanced at it for a few times, then shook his head and put it back into the brocade box, and ordered: "Let the big sacrificial altar try to plant Jiahe rice ears on one-third of an acre of land to see if it can be bred and hybridized. Really plant it." It doesn’t matter if you don’t come out. If you order the local officials who discovered Jiahe, they can just do good business and govern the people from now on, and stop thinking about offering Jiahe auspiciousness.”

Zhu Yijiong couldn't really scold and punish someone who was just offering good luck.

After all, the ancients really believed that this thing was auspicious, so they had no choice but to not reward it. As time went by, the local officials would naturally have no interest in dealing with these fictitious things.

Meng Yan, the daily commentator, remained silent and wrote: "On March [-]th, Raozhou Prefecture presented Jiahe, with one rice and five ears. Jiahe and five grains are long, and the king's virtue is prosperous, so the two seedlings will be beautiful together. In Zhou De, Three seedlings share the same ear; in Shang De, they have the same roots but different stalks; in Xia De, they have different roots and show the same beauty. This is the holy virtue of the Son of Heaven. However, it is said: Local governments are no longer allowed to bring in good harvests. The most important thing is to govern and care for the people. And to The emperor dedicated one-third of an acre of land to cultivate golden crops for the well-being of all people."

Zhu Yijiong used Jiahe for breeding and crossbreeding, just to try his luck. There is a high probability that it will not succeed. Such advanced technologies in later generations have not been studied yet.

Jiahe Xiangrui is just a small episode, and the northern war is finally about to begin.
