After destroying the caravan, Qin Chuan knew that the person was not Zhong Deguang, but a subordinate Xu Yijie specially chose to pretend to be a subordinate who was somewhat similar in height and appearance to Zhong Deguang.

Therefore, he did not send anyone to Dingxiang to find the Zhong family.

He didn't go to trouble King Ninghua, Xue Dongting and Xu Yijie.

After learning that the matter failed, these people definitely did not go out easily, and there were many guards in their own hands, so it was not so easy to kill them.

It's not too late to clean them up later.

Since the weather cooled down, Qinchuan sent people out to the transportation arteries of Lanzhou, Xingxian, Linxian and Yongning Prefecture to set up porridge sheds to relieve the hungry.

This winter, many, many people will freeze to death and starve to death.

The people who repair water conservancy still go out in groups every day, braving the cold wind to hoe and dig mud in the ravines, and the people who reclaim farmland do the same, so they have to reclaim as many acres of farmland as possible before the land is completely frozen.

The northwest of Shanxi is an arid and sunny area, now is not the coldest time, the land will be frozen hard at night, during the day by the sun shining on the water evaporation and thaw, and at night again and again, and so on, until the temperature continues to drop, the land will be completely frozen, if it snows, it will freeze faster.

At that time, all the work such as reservoirs, farmland, and roads will not be able to be done, and the people will have to stay at home to weave cloth and do some manual work such as bamboo baskets and sacks.

Qin Chuan went to Montenegro and inspected the mines and several factories, and then he stayed in Montenegrin Fort, playing rifled guns and twelve-pounder guns with Li Xuejing and Chen Zhan.

After touching for half a month, the first front-loading rifled flintlock pistol was made.

The spiral shaft was made by Qin Chuan's method, and after making three of them, one of them was finally qualified, and the rifling wire drawn out could finally meet Qin Chuan's requirements.

This first rifled gun was engraved with four yin lines, about 0.2 millimeters deep, parallel to the right, and it was very beautiful to look at closely when it was in the light.

With rifled guns, you have to get Mine.

If the previous round lead bullet was used, the same size as the caliber, the gas that would expand sharply when the gunpowder detonated would leak out of the rifling, resulting in a greatly reduced range and accuracy of the lead bullet, and even inferior to a smoothbore gun.

Before the advent of the Mine, European rifled guns used lead bullets slightly larger than the caliber, forced into the barrel, let the edge of the lead bullet into the rifling, and then hit the whole strip with a hammer to hammer the bullet into it.

This method avoids gas leakage to a certain extent, increases air tightness, and gives full play to the performance of rifled guns, but the reloading speed is not generally slow, more than twice as slow as smoothbore guns.

Because the reloading speed was not generally slow, the early rifled guns were not mass-assembled, but were only used by a small number of elite troops, such as the French chasseurs.

Until the advent of the Minne bomb.

This conical buckshot is slightly smaller than the caliber of rifled guns, and when loading, it can be stabbed with a stabbing strip, and there is no need to pad deerskin or paper, reducing one step, and the loading speed is faster than that of a smoothbore gun.

There is a hole at the bottom of the lead bullet, which is resisted by a wooden plug, and the gas formed by the deflagration of gunpowder when fired hits the wooden plug, and the wooden plug is pushed into the hole, and the bottom of the bullet is propped open, so that the bottom is embedded into the rifling, which plays the role of holding the air, and can also make the bullet rotate at high speed under the action of rifling, and the flight is stable, the range is longer, and the power is greater.

This thing is not difficult to make, just have a mold with good accuracy.

Qin Chuan asked Li Xuejing to make a rolling mold, then poured the boiling lead water into the mold, pressed the lid on the top down, and only waited for a short while, and after the lead inside cooled down, it was poured out, and the lead bullet could be obtained.

Qin Chuan did not rush to install the wooden stopper, but after making dozens of warheads, he put these warheads into an iron pot, and then mixed paraffin wax and graphite powder to make small round balls, which were also put into the pot and stirred with the lead warheads.

This is done by applying a layer of paraffin wax and graphite to the surface of the warhead to increase smoothness, reduce friction with the chamber, and reduce wear and lead trapping.

At the same time, when the friction is reduced, the rotational speed and muzzle velocity of the bullet will be slightly faster, which can increase the range and power to a certain extent.

After firing the warhead, Qin Chuan put a wooden plug on the tail of the bullet, took the barrel to the shooting range, loaded it with four times the propellant to test the strength, and after confirming that there was no problem, he began to install the butt and bolt and other parts.

Next, it's time to test the gun.

Qin Chuan asked Huang Liuxi to pick a few marksmen out and go to the shooting range to test the gun together.

When Huang Liuxi heard that this gun could shoot 300 steps, he still didn't believe it, thinking that the big boss was fooling him.

When they arrived at the shooting range, they saw a human-shaped target standing 100 paces, 200 paces, and 300 paces away, and dozens of people around them, the ugly face that had been injured by the explosion suddenly twisted into a bitter gourd.

"Big boss, you are deliberately making me ugly, how can you hit such a far target."

"Hey, hey, hey."

Qin Chuan patted him on the shoulder and said, "Don't worry, you're so ugly, you can't be ugly." ”

"Hmmm......"

Huang Liuxi didn't know how to refute for a while.

"Hurry up, start with a target of 100 paces."

Qin Chuan patted him on the shoulder again, and then took a few steps back.

Huang Liuxi had a bitter face, poured the gunpowder into the barrel, looked at the strange-shaped bullet for a long time, and then loaded it, and then put the gun on the wooden table in front of him, and lowered his head to aim.

It's strange to say that Huang Liuxi was blown up half to death by the bird's gun, and after picking up a life, his marksmanship became more and more accurate, as if the musket owed him a face and had to pay him a debt.

A distance of one hundred paces is not difficult for a rifled gun, and ordinary soldiers can hit it, not to mention Huang Liuxi.

After a "bang" gunshot, Qin Chuan raised his binoculars and looked at it carefully, and then nodded with satisfaction: "Yes, it's right in the bull's-eye." ”

Huang Liuxi was a little incredulous, picked up his binoculars and looked at it, and said "hey".

"The big boss, I use the best self-generated firearm, and I can't hit so accurately a hundred paces away, and this Rausch rifled gun you got is not bad."

"Don't talk nonsense, go down."

"Okay."

Huang Liuxi reloaded again, aimed at the humanoid target one hundred and fifty steps away, and fired a total of three shots, all of which hit the target, the most accurate shot was only two inches away from the bull's-eye, and the worse one was five inches off.

Huang Liuxi began to get excited.

Then there was the humanoid target of 200 paces, this time, one of the three shots missed, and the other two shots were also very deflected, one shot hit the lower abdomen of the humanoid target, and the other shot focused on the edge of the lower part of the target.

Huang Liuxi looked at it with a telescope for a while, and his face was full of disbelief.

Luo Daniu and other onlookers of the Guan Emperor army were also in an uproar, two hundred steps away, three shots in two, if they hadn't seen it with their own eyes, they wouldn't have believed that there was such a far and accurate musket in the world.

One step in the Ming Dynasty is about equal to one meter six in later generations, and two hundred steps is about three hundred and twenty meters, although there is a table gun, hitting the target at such a distance not only proves that Huang Liuxi's marksmanship is good, but also proves that the performance of this rifled gun is very good.

Immediately after that, he went to two hundred and fifty steps, and this time Huang Liuxi only hit one shot, and it was able to hit the edge of the lower end of the humanoid target, and he only barely hit.

After that, three hundred and three hundred and fifty steps, he missed all of them.

Despite this, Huang Liuxi was still excited, and several other marksmen were also eager to try this far-reaching and accurate sharpshooter.

Qin Chuan frowned and scratched his head.

He remembered that later generations recorded that the effective range of front-loading rifled guns used in Europe in the nineteenth century could reach 500 yards, or 460 meters, equivalent to 280 steps.

Effective range means the distance at which the expected accuracy and power can be achieved.

But after more than 200 paces of rifled guns, the accuracy dropped sharply.

Huang Liuxi's marksmanship is fine, but after two hundred steps, the accuracy is much worse, is it a problem with the gun?

Still is......

Qin Chuan suddenly slapped his head and secretly scolded himself for being stupid.

Ruler issues.

He didn't get the ruler out.

After the bullet is discharged, it flies in a very slight arc, and after flying out of a certain distance, there will definitely be a drop, and the human eye is in a straight line with the door and the front sight, and the accuracy will definitely be affected if the previous front sight is aimed and shot.

No wonder the bullets after two hundred paces are getting lower and lower.

After understanding what the problem was, Qin Chuan asked the rest of the marksmen to try the rifled gun, and then fixed the rifled gun and began to measure the trajectory and ruler.

Qin Chuan spent a whole day, through the different height of the ruler position, combined with the bullet landing point, through the comprehensive data of continuous testing, and finally set the 100 steps, 150 steps, 200, 250, 300 and 305 rulers.

The next day, Huang Liuxi used this rifled gun with a ruler on it to fight another round.

This time, he fired five shots at each target position 200 paces away, and the final result was: 200 steps 5 out of 4, 250 steps out of 5 out of 2, and 300 steps out of 5 out of 1.

With the ruler, the trajectory is not concentrated and deviated, it should be just that Huang Liuxi is not familiar with this gun, and after spending some time to get acquainted with it, the accuracy will definitely be improved.

Qin Chuan was very satisfied with this flintlock pistol, and asked Li Xuejing to continue to pull rifling and continue to make rifled guns on the same day.

It is also necessary to continue to build spiral shafts and increase the production line of rifled guns, the more the better.

The rifled barrel and the smoothbore flintlock pistol use the same kind of barrel, and it takes about six or seven days to pull out the rifling of a barrel, but the scrap rate is extremely high, and it completely depends on the skills and experience of the craftsman.

Qin Chuan had to train a few fine craftsmen first, and then throw a bunch of gun barrels for them to practice, and slowly cultivate them.

Therefore, if you want to mass-produce rifled guns, you must have a large number of skilled craftsmen and have enough lathes.

It will definitely not be possible in a short period of time, and it will take a lot of time for craftsmen to accumulate experience.

If he can make a hundred rifled guns before Huang Taiji enters the customs in May or June next year, Qin Chuan will be very satisfied.
