After sending the letter, Hao Fenglou was still a little annoyed.

In fact, he had the idea of ​​a rotating musket from the beginning. This idea came from some kind of YY. Thinking about it, although he was powerless, he was facing the enemy in the future. Someone rushed towards him with a machete. He pulled out the musket and shot five guns in a row. He blew the musket... He raised his cloak and blew the musket, and his face was full of loneliness.

With this idea, I want to put in practice. In fact, the structure of the rotary wheel musket is the simplest. Moreover, with the rotary wheel musket, I will first build the foundation of the flint gun. In the future, the flint gun can be modified into a flintlock musket. However, Hao Fenglou did not expect that he would ignore the most critical issue, that is, the range of the musket.

Because the barrel of this kind of musket is short, the biggest feature is that it is easy to carry, so the range is so low that it is only less than ten meters, and the effective range is only six or seven meters. Although the rotor musket is a sharp weapon for melee combat, such an effective range is really useless. The key to the problem is still on the rifle. You must know that later revolvers have rifles. Although the rifle is short, the bullet rotates rapidly with explosive force when firing, which greatly strengthens the thrust of the bullet and greatly improves the accuracy. Therefore, ordinary rotor muskets can theoretically reach a distance of fifty steps, and fifty steps are enough to become a weapon.

What Hao Fenglou ignored was this rifle. If the modified musket of Hao Fenglou greatly improved the smoothness of the inner wall of the musket and turned the rough musket into a real smoothbore musket, it can be said to be a qualitative leap in the history of the Ming Dynasty muskets, then if the rifle could be applied to the muskets, it would be another qualitative leap.

However, if you want to get the long gun nearly half a meter long to get the rifle in the camp, it is probably very difficult, because the barrel of the bird gun is originally slender, and its narrowness increases the difficulty of the process in a geometric multiple. But what about the short gun of the wheel? This seems to be much less difficult.

Hao Fenglou thought about it in the study for a long time, but finally couldn't sit still. Because his eyes fell on the secret book in the palace again, the secret book had been torn apart, and Hao Fenglou threw them into the incense burner. The incense burner suddenly shone brightly and flames ignited.

"It's too late to take time, so it's better to be on guard against it. Although the emperor and the master are extremely smart, they are very confident, but who would know if there will be any secrets? If they can use the rotary musket as soon as possible, they might be able to take precautions."

Thinking of this, Hao Fenglou cheered up and hurried out of the study room. Outside the study room, a servant from the mansion trotted up and said, "Master, please come over."

Hao Fenglou shook his head and said, "I have something to do here. If you go back and tell the master, you will listen to his teachings tomorrow. You can go to the horse house to prepare horses now. I will go out of the city."

The servant hesitated for a moment, but he still hurriedly went there.

The groom in Hao Fenglou, who was on a horse, left the city and arrived at the camp with a familiar car. In fact, before that, the camp had received a letter from Hao Fenglou. Some craftsmen's leaders gathered in the treasure building and were negotiating Hao Fenglou's so-called rifling process.

Baibao Building is a conference hall for craftsmen. Carpenters spent two months to build it. Generally, when encountering some major events, some craftsmen with higher ranks will gather here for consultation. Every time there are special records of clerks, and then archive them, which can be used as reference in the future.

More than a dozen highly respected and skilled blacksmiths gathered together at this time to analyze the principle of rifle, which was spiraled. The function was actually to jamm the lead bullet. After being subjected to the huge thrust of gunpowder, the lead bullet would sprint forward quickly along the rifle, and a certain inertia arose in this process. Finally, the lead bullet was shot out of the musket in a rapid rotation, thereby greatly improving the accuracy, impact force and inertia.

The so-called "principles" written by Hao Fenglou in the note is actually understood by everyone, but the problem is that it is obviously not easy to rifle on the inner wall of the musket.

After we got together to discuss, we finally concluded that there were only two ways to get rifle, one was the so-called casting mold and the other was file. The former was difficult. Although the casting mold skills were already very high, it was a bit disappointing to get the rifle texture on the mold; as for the method behind it, it was a stupid method, and it was directly used to dig out the rifle by hand, which not only made the rifle uneven, easily errors, but also time-consuming and labor-intensive.

After the discussion, there was no result and the hall fell into silence; and just then, Hao Fenglou arrived.

Hao Fenglou didn't say much, and came up with a plan straightforwardly, directly ordered people to create a hook-shaped cutter and then penetrate the gun barrel by rotating. This method is like a bottle cap from later generations, and the bottle cap is tightened by rotating.

The method was very simple and feasible. Early American colonists used this method to build chambers. The tools were very simple manual wooden machinery and cutting knives. Those colonists who basically did not have many mechanical tools could make them by themselves. The camp was obviously much better than the colonists at that time. After Hao Fenglou came up with the plan, everyone immediately started to do it. First, they asked the carpenter to create a simple wooden machine tool, and then a spiral cutter with hooks. Someone fixed the cutter on the wooden machine tool and used a musket to experiment. Sure enough, a rifle with almost no error was formed inside the musket.

The iron filings inside were shaken off one after another, and lubricants such as lard were re-administered. They held a cotton-filled cloth plug and wiped it clean. After confirming that there were no flaws, the next problem to be solved is to make lead bullets that match the rifling.

Because of rifling, there is a concept of bullets. Bullets must fit the rifling, otherwise they will be easily stuck by muskets. Fortunately, Hao Fenglou did not expect to create exquisite bullets from later generations. He just hoped to produce solid lead bullets that fit the rifling. The process requirements were not too high. After several mold masters accurately calculated the calculations, they began to model, pour in lead water, and after cooling, the lead bullets formed.

A true rotary wheel musket fell into Hao Fenglou's hands. Hao Fenglou seemed quite excited. After ordering people to get the ammunition, he held the heavy rotary wheel musket in his hand. Hao Fenglou felt like he was going back to the past.

He arrived at the schoolyard, and countless craftsmen and musketeers also surrounded him. Hao Fenglou directly pressed the trigger. When the trigger moved, the striker behind the musket hit the flint groove with a bang. The gunpowder in the groove suddenly made a loud bang, and the huge white smoke expanded out. The lead bullet aimed at the rifle quickly advanced along the gun barrel under the huge force. With the spiral rifle, it rotated rapidly, and finally sprayed out the gun barrel like a fire snake, and sprayed directly towards the target.

Then... I missed!

The target did not move at all, and only God knows where the lead was ejected.

Hao Fenglou was ashamed and called Liu Yang, a hundred households of the Musket Team, in disappointment, and said, "Come and try it."

Liu Yang responded quickly, unable to bear to see the embarrassment on Hao Fenglou's face, so he took the rotary wheel musket, thrust the rotary wheel, stood still, and shot at the target.

Bang……

The wooden target was pierced immediately and it was smashed.

Liu Yang said: "There is a total of twenty steps away from the target. Twenty steps can penetrate the wooden target, which is indeed more than twice as sharp as just now."

Hao Fenglou said: "Calculate how much effective the range can be."

Liu Yang nodded, continued to retreat, shoot, and after shooting, he recorded the data, then took another ten steps back and fired until all the gunpowder and lead bullets in the rotor were shot. He took the data and pondered for a moment, and came to report to Hao Fenglou: "Sir, the effective range should be about thirty steps, close to a distance of ten to fifteen feet, but even within fifty steps, there is a certain penetration power. Only after more than thirty steps, the accuracy may not be accurate."

Thirty steps are simply a qualitative leap compared to the first ten steps. The revolver musket in later generations is roughly about fifty steps. The revolver musket may not pursue the maximum range. After all, no matter how short the gun is, it is impossible to compare with the long gun. If the bird gun is a weapon to deal with the cavalry when the two armies are fighting each other, then the short gun in Hao Fenglou's hand is a magic weapon when fighting fierce battles or close combat. In the melee, your enemy is only ten meters away from you. They rushed towards you, you raise your hand and knock him down directly. This feeling must be very pleasant. Moreover, although revolver musket is more troublesome to load gunpowder, after all, you have to load five shots at a time, but don't forget that once it is installed, you can attack five times in a combo. It's a common small-scale battle, I'm afraid that your ammunition will end before it is finished.

This is definitely a huge advantage, and it is also very wide-ranging. Hao Fenglou smiled and called Hao San and said, "Just use this method to build a batch of rotary wheel muskets. It is necessary to speed up. Can I do it before the young master gets married?"

Hao San scratched his head and said, "Unless you put down everything else, this short gun is too cumbersome to build..."

Hao Fenglou said seriously: "It's settled. Put down all the others in advance. The fire gun team will immediately train the fire gun team to familiarize them with it. Without further ado, start now. Don't be in a difficult position. If it's not difficult, what should I do for you? Let's tell you the truth, your young master may not be able to be peaceful when he gets married. If something really happens, we have to protect ourselves. These short guns are our trump card, do you understand?"

When Hao Sanyi heard this, he realized that he was amazing and hurriedly said, "Yes, yes... Master, don't worry about entering your bridal chamber, just leave the rest to me."
