The Minni rifle uses the round-head cylindrical shell lead bullet invented by Minni. Since this bullet is slightly smaller than the rifle, it solves the embarrassing situation when the old rifle is loaded in front of the bullet, and the barrel cannot be plugged in or blocked due to the large bullet. The Minni rifle can easily push into the barrel with the push rod, which greatly improves the rate of fire. The bullet is threaded around the body to match the rifle, and the middle of the thread is filled with animal oil. The bottom of the bullet is made of cork material.

When firing, gunpowder gas impacts the cork, and the cork suddenly supports the bullet after being hit instantly. Since the bullet is supported, the chamber sealing can be completed by relying on the bullet itself at the moment of launch, without leaking the gunpowder gas, causing the kinetic energy of the bullet to be lost. This solves the problem of the chamber sealing of the old-style front-loading gun, thus greatly enhancing the rate of fire, range and safety of the gun (good sealing is not likely to cause gunpowder residue to block the barrel and cause a blow-off).

Before the emergence of Minni rifles, smoothbore rifles were practical weapons, and all the armies of the great powers used smoothbore rifles. The rifled rifles were just an experimental weapon and were not the main force on the battlefield. The main problem of rifled rifles was that it was difficult to maintain the air-holding of the gun in front of the bullet, and the power was greatly reduced. In order to achieve good air-holding, the caliber of the rifled rifle bullets was often the same as the caliber of the gun and even slightly larger.

Therefore, it is extremely difficult to load, and often requires a hammer to beat the push rod to push the bullet into place.

As a result, this often leads to more dangerous rupture of the barrel. When the bullet is pushed to the drug room, it is often deformed due to rough operation, which cannot achieve the killing effect. The emergence of the Minni rifle solved these problems. After solving these problems, the power of the rifle was fully demonstrated. The equipment of the Minni rifle greatly enhanced the firepower of the French army.

The Minni rifle is equipped with a safety lock to prevent fire.

The entire gun weighs 4.8 kilograms, a diameter of 17.8 mm, and a bullet weighs 32.4 grams. The killing distance can reach an astonishing 918 meters, which can ensure accurate hit within 550 meters. The Minni rifle was quite powerful at that time. Tests conducted in 1849 AD found that the Minni rifle could penetrate two poplar wood boards within 15 yards and penetrate 20 inches deep into the third wooden board. Because of the huge power and strong firepower of this rifle, for a while, rumors claimed that the Minni rifle could penetrate a person with one shot and then break through anyone within 15 meters of its ballistic.

In fact, actual combat proved that the power of the Minni rifle was indeed amazing. In 1846 AD, French hunters used Minni rifles for the first time in Africa, and the effect was good. They were also used in a small number of Crimean War. When the Civil War broke out, Minni rifles quickly became the standard equipment for the two armies with their huge lethality. Starting from 1851 AD, the British army also tried to use Minni rifles. Later, the Minni rifles were transformed into the US Springfield rifles and the British Enfield rifles.

However, no matter how powerful the Minnie rifle is, it is a borebre gun after all. When it was born, the technology of the breech gun was basically mature. The emergence of smokeless gunpowder, mercury, and fire caps made the breech gun quickly replace the borebre gun and become the main force in the battlefield. Compared with the breech gun of the same period, the Minnie rifle has too many shortcomings, especially the inability to crawl, which has become the most fatal flaw. In front of the breech gun that can crawl, the Minnie rifle who must stand to shoot is completely a living target.

During the Pudong-Austrian War in 1866, the old Minni rifle suffered a heavy defeat on the battlefield. In the battle of infantry firepower, the Pudong-Bulley Dresey firing gun easily defeated the already old Austrian Minni rifle. The shocked French army decided to fully equip the Xiaspo rifle with bulley firing gun. At this point, the Minni rifle officially withdrew from the historical stage.

It can be said that the Minnie rifle is the pinnacle of the bore-bending rifle. Without smokeless gunpowder, no mercury, and no fire cap, the breech gun would not be able to replace the bore-bending rifle. The Minnie rifle, which was born at the wrong time, was like a flash in the pelvis, only existed in history for about 20 years. However, its glory left a very deep impression on later generations. If it were invented earlier and made earlier, the history of the world would have been completely changed.

Zhang Zhun thought of the Minni rifle because the barrel problem of the Lumi gun could not be solved. If the process of the Lumi gun could not be solved, he would not consider the smoothbore gun at all. Because ordinary smoothbore guns are not as useful as triangular pierced spears and spears. According to Zhang Zhun's understanding, even the worst rifled rifle is better than the best smoothbore gun in terms of accuracy and range. It is precisely based on this understanding that Zhang Zhun decided to make a rifled musket. Even the quality of this musket may be terrible at the beginning.

"The barrel is rifled!"

"Use flint to fire!"

"The range is three hundred feet!"

"Accurate hit within a distance of 150 feet!"

Zhang Zhun summarized several key points of the Minnie rifle.

Zhou Shiwen and Luo Dashan looked at each other again.

The other craftsmen were even more confused and full of yearning.

There is such a magic weapon in the world? Can such a magic weapon be really made? You must know that the range of ordinary Folang cannons is only 180 meters! It is a cannon, not a fire gun! Could it be that a small-caliber musket can have a range of more than one cannon? It is really incredible.

“Incredible!”

“Incredible!”

“Incredible!”

These four words are repeatedly echoed in the heart of almost every craftsman.

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

Of course, Zhang Zhun was very clear about this. Just like the steam catapults in later generations, many countries actually understood the principle of it, but unfortunately they were made. There was no way, and the technology could not meet that requirement. However, all this did not exist in the Ming Dynasty. The technology of the Ming Dynasty was definitely among the best in the world at that time. Even if it could not be said to be the world's number one, there would definitely be no problem with the top three in the world.

"Rifled!"

Regarding the Minnie rifle described by Zhang Zhun, the two found the key problem without thinking. Yes, the key to everything lies in rifle. The biggest difference between a rifle and a smoothbore rifle lies in rifle. The greatest difficulty of the process lies in rifle. The problem of rifle is not solved. Everything Zhang Zhun described is a mirror and a castle in the air.

Zhou Shiwen said bluntly: "Sir, how can we solve this problem of rifling?"

Zhang Zhun said confidently: "We will go to the craftsman workshop to study it slowly, and I will demonstrate it on site for you to see."

As soon as the two spoke, Zhang Zhun knew that they would catch the core of the problem. Yes, the core of all problems lies in rifles. In fact, he was also very careful to think about the core of this problem. The advantage of rifles over smoothbore rifles is that their barrels have rifles, which can give the projectiles higher accuracy. Therefore, rifles are the key to the key. However, how to create rifles is indeed very exquisite. Without rifles, everything is useless. If he had not mastered the method of creating rifles, 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 originally outdated craftsman workshop was greatly improved when the guards entered the city. Zhang Zhun approved 500 taels of silver on the same day, handed it over to Ma Yi, and handed it to Zhou Shiwen and others for various production tools. The most important thing is to uniformly standardize all measurement tools. All errors that can be seen in the naked eye will be replaced. At the same time, the working environment has also been improved.

The original craftsman workshop was dilapidated, dust was everywhere, and mice were rampant. In such an environment, no one dared to use the weapons produced. After a major cleaning and repair, the craftsman workshop became much brighter and there was no floating dust in the air. All the tools were wiped clean and neatly arranged.

Zhang Zhun walked around Jiangshuo Workshop and was quite satisfied with the working environment here. Although it did not meet the current factory requirements, it was already quite outstanding under the conditions at that time. In the future, Jiangshuo Workshop will continue to expand and expand it into a large-scale firearm processing factory and assembly line production firearms.

"Come here and listen to my detailed explanation."

After sitting down, Zhang Zhun began to explain in detail how to create rifles.

Perhaps, in the eyes of many people, rifling is a very high-tech difficulty and requires very professional tools. At least, Zhou Shiwen and Luo Dashan both think so. In fact, rifling is not mysterious, and someone has produced it a long time ago.

According to literature records, Italy had a spiral-shaped rifled gun as early as 1476. The spiral rifled can make the projectile rotate and fly stably in the air, improving the accuracy and range of shooting. "Rifled" is rifile in English, transliterated as "Rifled", and the rifled rifled is also called "Rifled". In the early 17th century, the Danish army first equipped rifled rifled. However, due to the high cost of making reams and inconvenient loading ammunition from the muzzle, the armies of many countries are unwilling to equip guns with spiral rifled.

If you use a rifled rifle, two technical problems must be solved:

The first is to create a spiral rifle.

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