When he came back from Shouningbo's Mansion, Zhu Houwei found more than a dozen masons with good skills in Huangzhuang, gave them a stack of drawings, and then asked them to discuss whether they could build it.

It takes time to build a house, and what Zhu Houwei wants to build this time is a relatively large building, so he can only wait slowly.

News came from the munitions factory that a new flintlock pistol had been made. When the Zhu Houzhao brothers heard the news, they immediately took Liu Jin and the guards and took a carriage to leave the capital.

The military factory is located in the southwest of the capital, about 10 miles away from the water and land camp, and the surrounding area is empty. It took 1 hour for the carriage to arrive, and because the road in the second half was difficult to walk, most of the manpower was now spent building roads and reservoirs between the various royal villages in the Gyeonggi area, and there was really no one to build a road connecting the capital to the military factory.

The military factory is in the mountains, and there is a road to the north and south to lead to it, and now the checkpoints have been built at the two exits, which is easy to defend and difficult to attack. Far away, you can see the tall checkpoint, although it can't be compared with the city wall of the capital, but it is also about 8 meters high. The walls are about 6 meters thick and 300 meters long, and you can ride on them. All kinds of fortification facilities are complete. The walls were built of cement and good steel (much worse than in later generations, but it was a good time), and small-caliber cannons could not threaten the walls.

There are 10 soldiers of the land and water battalion patrolling the city wall, after all, this is the top priority for the two Zhu Houzhao brothers, and there is no room for mistakes, so the soldiers of the land and water battalion are sent to defend.

The current person in charge of the military factory is Li Tiezhu, the youngest son of Li Deli. Although he has no cultural knowledge, he is diligent and has been studying in the past few years, and he is also very smart, which reassures the Zhu Houzhao brothers.

Under the guidance of Li Tiezhu in front of the checkpoint, Zhu Houzhao and his party soon came to the gunsmith factory. The director of the factory here is called Wu Jiabao, who is just over 50 years old, and he used to make firearms for the imperial court, and he has rich experience, and he was later dug up.

After Wu Jiabao stepped forward to salute, he didn't say much, and took the two brothers to a school yard behind the manufacturing factory. The school field is narrow from east to west and wide from north to south, about 100 meters from east to west, and 300 meters from north to south. There is no fence on one side of the mountain, and the other three sides are concrete walls about 2.5 meters high.

When he came to the school field, Wu Jiabao had already prepared all the guns, there were two kinds of guns, both of which were rifled guns, one was a straight rifled gun, and the other was a diagonal rifled gun. The length of the two guns is basically the same, and under Zhu Houwei's previous guidance, the length of these two guns has been deliberately shortened. The flintlock pistols of the amphibious battalion are now about 1.5 meters long, and the soldiers are 1.7 meters tall, so they are a bit troublesome to load.

Zhu Houzhao picked up a straight-line rifled gun and examined it carefully. The butt of the gun is made of pear blossom wood, and all the other iron parts are rubbed with tung oil, which makes it look dark and shiny, which is very popular. The butt plus barrel is only about 1 meter 4, which is very good for reloading. Now what is worrying is its effective range, after all, if the barrel is shortened, the range will also be reduced to a certain extent.

Zhu Houwei also picked up a straight-line rifled gun, and then began to load ammunition. Speaking of this bullet, I can't help but make a special note. Because this is not an ordinary buckshot bullet, but a mini bullet that was originally born at an inopportune time in history.

Mini bullets, the diameter of the conical warhead is slightly smaller than the diameter of the breech, so it is convenient to reload. There is a conical cavity at the bottom of the warhead, a wooden plug blocks the bottom of the hole, and when firing, the gas presses the wooden plug to squeeze into the cavity, forcing the bottom of the bullet to expand, close to the rifling, and close the gap between the warhead and the rifle, so that the gas cannot leak out, and can make the warhead rotate at high speed under rifling pressure. The Mini bullet solved the problem of the difficulty of loading the front-loading rifled gun and the low range accuracy of the smoothbore gun, which made the rifle surpass the artillery and become the decisive weapon on the battlefield at that time.

But there are some problems that cannot be solved with the Mini bullet, which can only be made of a very soft alloy such as lead, so that the warhead can expand easily. The warhead is soft, it deforms immediately after hitting the target, the stopping effect is good, but the penetration is too weak.

Weak penetration is not a big problem for the current war. Even if the enemy wears strong armor, the kinetic energy generated by the bullet hitting the armor is enough to stun the enemy or even kill him.

After the loading, both Zhu Houzhao brothers began shooting. The target was made of thick wood, a circle with a radius of about 50 centimeters, and the first time the gun was fired, the distance was 50 meters.

"Bang bang" twice, a burst of white fog, Zhu Houzhao's target pierced a hole, and Zhu Houwei's target was safe and sound, obviously off target. Zhu Houwei rubbed his shoulder, which was a little painful, and thought to himself, "It's still too small, and the body can't stand such recoil." ”

Zhu Houzhao was very happy, continued to put the wooden rake 70 meters away, and shot again. Only to hear a bang, the wooden rake pierced again. Seeing such a result, the Zhu Houzhao brothers were very satisfied, because it was really good to have such accuracy at a distance of 70 meters. The range of precision has surpassed the range of the Tartar's bow and arrow, and it is of great significance for warfare.

Immediately afterwards, Zhu Houzhao experimented for 80 meters, 90 meters, 100 meters, and did not stop until 150 meters. Zhu Houzhao really can't put down this gun, within 120 meters, basically do not miss the target, 120 meters to 130 meters can also have 10 5, to 150 meters, the hit will be 10 to 2.

Zhu Houwei thought about it in his heart, in this way, he can basically shoot at 110 meters, which is not a little better than the previous smoothbore gun. The difference between 110 meters and the range of the Tartar's bow and arrow is 60 meters, which means that after the Tartar receives the first round of gunfire, it has to run 60 meters to shoot the bow and arrow, and this 60 meters takes about 6 seconds, which is enough for the second round of shooting. After 2 rounds of shooting, only God knows how many people will be left to run to 50 meters to shoot arrows.

The Zhu Houzhao brothers are very happy, but there is still a sharp weapon that has not yet been test-fired, that is, a slash rifled gun. The same loading, the same target, but at 70 meters it was already beginning to show how good this gun was. Because at this distance, the bullet shot by Zhu Hou almost hit the red heart of the wooden rake, which means that the accuracy is very high.

Zhu Houzhao immediately gave up the straight rifled gun just now, and devoted his love to the slash rifled gun. Immediately afterwards, the wooden rake slowly moved away, until 150 meters, the bullet can still shoot to the middle position, and below 140 meters, it basically hits the red area, of course, this is also related to Zhu Houzhao's marksmanship.

It is difficult to control the accuracy beyond 150 meters, which is mainly a personal ability, after all, after 150 meters, a circle with a radius of half a meter is only the size of a coin to the naked eye, and it is also a dime in later generations.

The sharpest thing about this gun is that even if it doesn't hit the wooden rake, it can fly to the wall, which means that the range has exceeded 300 meters, flying over the entire school field, making Zhu Houzhao almost jump with joy.

However, this gun is not without drawbacks, due to the slash, the bullet flies out of the barrel and the whole process of severe friction with the rifling, for the rifling wear is serious. After firing 100 shots, the accuracy began to decline, and when it reached 200 shots, it was basically 100 meters away from the target. These data are not derived by Zhu Houzhao, after all, it takes too much time to fire 200 guns.

Under Zhu Houwei's question, Wu Jiabao began to introduce the data of the two guns. The first is the straight-line rifled gun, which can basically maintain 300 to 500 shots for accurate shooting due to the slightly less rifling and bullet friction, while the basic life of the slash rifled gun is 150 shots. Once the rifling of the barrel is smoothed, it can only be rebuilt. Both rifled guns are time-consuming, and the most critical thing is rifling. It takes 1 craftsman nearly 5 days to drill a barrel, and even if an assembly line is used, a gun takes 2 days, and the only way to solve it is to continue to increase the number of people.

Under the discussion of the Zhu Houzhao brothers, the straight-line rifled gun was called the Dingyuan gun, while the oblique rifled gun was named the sharpshooter. Since both guns were made in the first batch and may be improved in the future, they are both called Dingyuan Type 1 and Shenjian Type 1.

After discussing with Zhu Houzhao, Zhu Houwei finally decided that all the soldiers of the land and water battalion would be equipped with the Dingyuan 1 type, and the gun factory would wait until Zhu Fu brought a scope and installed it on the Shenjian 1 type, and then produced it in small quantities, and finally equipped it with a better marksmanship for the water and land battalion.

At present, in addition to improving these two types of guns, it is also necessary to develop cavalry short guns suitable for cavalry to shoot on horseback, and pistols that are easy to carry and operate.
