The Mini rifle uses the cylindrical shell lead bullet invented by Mini. Since this bullet is slightly smaller than the caliber of the rifle, it solves the embarrassing situation of the old rifle's frontloading bullet that cannot be stuffed into the barrel or clogs the barrel due to the large bullet. Mini rounds can be easily pushed into the chamber with a ram lever, which greatly increases the rate of fire. The bullet is threaded around the body to match rifling, and the middle of the thread is stuffed with animal oil. The bottom of the bullet uses a cork material.

When fired, gunpowder gases hit the cork, and the cork was hit by an instantaneous impact, and then the bullet was violently propped up. Because the bullet is propped up, the chamber can be sealed by the bullet itself at the moment of firing, without leaking gunpowder gases and causing the kinetic energy of the bullet to be lost. This solves the problem of the sealing of the chamber of the old front-loading gun, which greatly enhances the rate of fire, range and safety of the gun (good sealing is not easy to cause gunpowder residue residue to clog the barrel and cause explosion).

Before the advent of the Mini rifle, smoothbore guns were practical weapons, and the armies of the great powers all used smoothbore guns. The rifled gun is only an experimental weapon, not a workhorse on the battlefield. The main problem with rifled guns is that due to the engraving of rifling, it is difficult for the front-loading bullet to keep the rifle closed, and the power is greatly reduced. In order to achieve a good apnea surname, rifled gun bullets are often made of the same caliber as the gun caliber or even slightly larger. As a result, loading is extremely laborious, and it is often necessary to hammer the pusher lever to propel the bullet into place.

As a result, this often leads to a more dangerous rupture of the breech. When the bullet is advanced to the position of the medicine room, it is often deformed due to rough operation, and the killing effect cannot be achieved. The advent of the Mini rifle solved these problems. After solving these problems, the power of the rifled gun is fully revealed. The armament of the Mini rifled gun greatly increased the firepower of the French army.

The Minnie rifle is equipped with a safety lock to prevent misfire. The whole gun weighs 4.8 kilograms, the caliber is 17.8 millimeters, each bullet weighs 32.4 grams, and the killing distance can reach an astonishing 918 meters, and accurate hits can be guaranteed within 550 meters. The Mini rifle was quite powerful at the time. Tests conducted in 1849 found that the Mini rifle could penetrate two aspen planks within 15 yards and penetrate 20 inches deep into the third plank. Because of the sheer power and firepower of this rifle, rumors spread that the Mini rifle could penetrate a person with a single shot and then penetrate anyone within 15 meters of its trajectory.

In fact, the power of the Mini rifle proved to be amazing. In 1846, French hunters used mini rifles for the first time in Africa, and the results were good. It was also used in small quantities in the Crimean War. At the outbreak of the American Civil War, the Mini rifle quickly became the standard equipment of both armies due to its great lethality. Beginning in 1851, the British army also experimented with the Mini rifle. Later, the Mini rifle was modified into the U.S. Army Springfield Rifle and the British Army Enfield Rifle.

However, no matter how powerful the Mini rifle is, it is a breech gun after all. When it was born, the technology of breech guns was basically mature. The advent of smokeless gunpowder, thunder mercury, and fire caps allowed breech guns to quickly replace breech guns as the main force on the battlefield. Compared with breech guns of the same period, the Mini rifle had too many shortcomings, especially the inability to shoot prone, which became the most fatal flaw. In front of the breech gun, which can shoot prostrately, the Minnie rifleman, who must stand and shoot, is completely a live target.

During the Austro-Prussian War of 1866, the old Mini rifle suffered a crushing defeat on the battlefield. In the infantry firepower, the Prussian breech Dreser pin gun easily defeated the aging Austrian front-loading Mini rifle. The French army was taken aback, and then decided to fully equip the Chaspor rifle with breech-loading firing pins. At this point, the Mini rifle officially withdrew from the stage of history.

It can be said that the Mini-type rifle is the pinnacle of breech guns. Without smokeless gunpowder, without the invention of the mercury of thunder, without the invention of the fire cap, it would not have been possible for the breech gun to replace the breech gun. The Mini-style rifle, which was born at an inopportune time, has only existed for about 20 years in history. But its brilliance has left a very deep impression on later generations. If it had been invented and manufactured earlier, the history of the world would have been completely changed.

Zhang Zhun thought of the Mini-style rifle entirely because the barrel problem of the Lu Mi gun could not be solved. If the craftsmanship of the Lumi gun could not be solved, he did not think about the smoothbore gun at all. Because ordinary smoothbore guns are not as good as triangular thorns and spears. According to Zhang Zhun's understanding, even the worst rifled guns are better than the best smoothbore guns in terms of accuracy and range. It was based on this understanding that Zhang Zhun decided to make rifled firearms. Even the quality of this firearm may be miserable at first.

"The barrel is rifled!"

"Fire with flint!"

"The range is three hundred feet!"

"Accurate hits at a distance of one hundred and fifty zhang!"

Zhang Zhun summed up several key points of the Mini rifle.

Zhou Shiwen and Luo Dashan looked at each other again.

The other craftsmen were even more dazed, and at the same time full of yearning.

In the world, there is such an artifact? Can such an artifact really be made? You must know that the range of the average Franc machine gun is only 180 zhang! It's a cannon, not a firecracker! Could it be that a small-caliber firearm can have a range greater than a cannon? It's incredible.

"Incredible!"

"Incredible!"

"Incredible!"

In the heart of almost every craftsman, these four words echo repeatedly.

Zhou Shiwen and Luo Dashan have a good habit, that is, if they think that your proposal is not good, they will not refute it in person, but carefully think about the details. As long as you find a problem in a detail that cannot be solved, then your whole suggestion is useless. Because of manufacturing technology, the most difficult thing to solve is often the problem of details.

Of course, Zhang Zhun is also very clear about this. It's like the steam catapult of later generations, in fact, many countries understand its principle, but unfortunately it is manufactured. There is no way, the process cannot meet that requirement. However, all this did not exist in the Ming Dynasty. The technology of the Ming Dynasty, in the world at that time, was definitely among the best, even if it cannot be said to be the first in the world, there must be no problem with the top three in the world.

"Rifling!"

For the Mini-style rifle described by Zhang Zhun, the two found the key problem without thinking. That's right, the key to everything is rifling. The biggest difference between rifled guns and smoothbore guns is rifling. The greatest difficulty of the process is also in rifling. If the rifling problem is not solved, everything described by Zhang Zhun is a mirror and a castle in the sky.

Zhou Shiwen said bluntly: "My lord, how to solve this rifling problem?" ”

Zhang Zhun said confidently: "Let's go to the craftsman's workshop to study slowly, and I will demonstrate it to you on the spot." ”

As soon as the two spoke, Zhang Zhun knew that the two would grasp the core of the problem. That's right, the core of all problems lies in rifling. In fact, for the core of this issue, he also thought about it very much. The advantage of rifled guns over smoothbore guns is that their barrels are rifled, which can give the projectile a higher degree of accuracy. Therefore, rifling is the key of the key. However, how to make rifling is indeed very exquisite. Without rifling, everything is for nothing. If he hadn't mastered the way to make rifling, he would never have made this suggestion.

Everyone immediately set off and came to the craftsman's workshop in the southeast corner of Fushan City.

The original old artisan workshop was greatly improved when the escort entered the city. Zhang Zhun approved 500 taels of silver on the same day, handed it over to Ma Yi, and handed it over to Zhou Shiwen and others to improve various production tools. Among them, the most important is to standardize all measurement tools. Anything that has a visible error is replaced. At the same time, the working environment has been improved.

The original craftsman's workshop was dilapidated, dusty, and rat-infested. In such an environment, the weapons produced are afraid that no one will dare to use them. After a major clean-up and repair, the workshop was much brighter, and there was no dust in the air. All the tools were wiped clean and neatly arranged.

Zhang Zhun took a turn in the craftsman's workshop and was quite satisfied with the working environment here. Although it could not meet the requirements of the current factory, it was already relatively good under the conditions at that time. In the future, the craftsman workshop will continue to expand, expanding it into a large-scale firearms processing factory, assembly line production of firearms.

"Come here, everyone, and listen to my detailed explanation."

After sitting down, Zhang Zhun began to explain in detail how to make rifling.

Perhaps, in the eyes of many, rifling is a very high technical difficulty and requires very specialized tools. At the very least, Zhou Shiwen and Luo Dashan both think so. In fact, rifling is not mysterious, it was produced a long time ago.

According to the literature, spiral-shaped rifled guns were first available in Italy in 1476. The spiral rifling allows the projectile to rotate and fly stably in the air, increasing the accuracy and range of the shot. "rifling" is rifile in English, transliterated as "rifling", and the rifled gun is also called "rifled gun". At the beginning of the 17th century, the Danish army was the first to be equipped with rifles. However, due to the high cost of making compound wires and the inconvenience of loading ammunition from the muzzle, the armies of many countries are reluctant to equip guns with spiral rifling.

In the case of rifled guns, two technical problems had to be solved:

The first, the manufacture of spiral-shaped rifling.

The second, to solve the problem of loading from the muzzle.
