was poured down by Wang Yu with a basin of cold water on his head, and Xue Fengzuo's heart was cold: "How do you say this?" Since the student's bottom expansion bullet has a low cost, a long range, and can be put into use in large quantities right away, why produce a rear-loading gun with a high price, complex production, and long production cycle? ”

Wang Yu picked up a rear-loading gun made by Dai Cang's father and son, pulled the bolt, and under the action of the linkage bolt, the cover plate on the bolt opened, revealing the chamber of the loaded bullet. Pen & Fun & Pavilion www.biquge.info Then he took a paper bullet from Dai Zi's hand, this bullet is a paper bullet that uses a thunder gong primer, and the paper bullet case made by Xue Fengzuo is a fixed Mini bullet, and the rear loading gun is a firing pin gun, which is fired with lei mercury primer. And Xue Fengzuo's Mini bullet is still ignited by a flint engine.

In fact, as early as three years ago, Dai Cang and his son had already come up with a rear-loading gun, because the technology was immature, the air leakage was serious, and the barrel was difficult to process after it was long, and there was no steam engine at that time, so the technology of the rear-loading gun could only be used on the Thunderbolt short gun, and the pistol with a short range had much lower technical requirements.

At that time, a small number of breech-loading spears were also made, but there were many problems, because of the serious air leakage, resulting in insufficient chamber pressure, and the power of the bullets was seriously weakened. If the charge is increased, there is a risk of blowing up the chamber. Therefore, at the beginning many rear-loading guns were reverted to smoothbore rear-loading guns, and rifling was eliminated.

Dai Zi, who created a series of guns in real history, can be said to be a firearms genius, and let him and his father join forces to jointly develop a rear-loading gun, which is indeed to exert his talent. After three years of unremitting efforts, Dai Cang and his son finally created a rear loading gun that could be truly put into use and could be put into mass production. It's just that the bullets currently used can only be paper bullets, and the technology of metal shell bullets is too complicated.

Although Dai Cang and his son tried their best to develop a rear-loading gun, due to the technical constraints of this era, the problem of air leakage could not be completely solved, so the chamber pressure of the rear-loading gun was significantly lower than that of the front-loading rifled gun, and the firing range was nearly half.

Xue Fengzuo said unconvinced: "The range of this gun is too close, although the rate of fire is fast, but with the student's gun, if the enemy uses the rear-loading gun, I'm afraid that the enemy has not yet approached the range, and only half of it is left!" The same number of people, with rifled guns of students, definitely prevailed! ”

"Even if there are only half of the people who use the rear-loading gun left, but we have a fast rate of fire, as long as we enter the firing range, we can beat you with the front-loading gun!" Dai Zi retorted unconvinced.

Xue Fengzuo picked up a grenade: "Don't forget this!" Your men are in range, and our men will be able to rush within forty paces as long as they fight to withstand your shots, and greet you with this thing! ”

Wang Yu suddenly laughed: "What Mr. Xue said is indeed very reasonable!" Front-loading rifled gunners, shoot with guns from afar, and use grenades when you get close! But that was based on the two sides lining up face-to-face to shoot! What if you change your tactics? The rear-loading gunner goes into range and will not lose a few people either! ”

After speaking, Wang Yu suddenly lay on the ground, picked up the gun, slowly crawled forward, crawled to within seventy steps of the target, picked up the gun and pulled the trigger, "bang" a gunshot, and a bullet hole appeared on the target. Immediately afterwards, Wang Yu did not stand up, but lay on the ground to reload the bullet! Soon another bullet was shot out and hit the target accurately!

"Everybody's seen it, right?" Wang Yu walked back with a gun, "This is the benefit of a rear-loading gun!" Our people can crawl on their stomachs, they can reload their bullets on their stomachs! Lying on the ground, it will be difficult for the opponent to hit! Creeping forward, from two hundred steps to seventy steps, how many of us can the opponent kill? But we are seventy paces, and the rate of fire is extremely fast, and can the opponent's front-loading gun lie on the ground and reload? So, the trend of the future is definitely rear-loading guns! ”

Dai Cang Dai Zi father and son were overjoyed, Wang Yu's words also meant that the weapon they had worked so hard to develop was recognized by the marshal!

Xue Fengzuo and Mei Wending's master and apprentice were a little depressed, and Xue Fengzuo shook his head, looking very disappointed.

But Wang Yu walked up to Xue Fengzuo and patted him on the shoulder: "Mr. Xue, the bottom expansion bomb you developed has not wasted your efforts in vain!" This is a very important transitional weapon! After all, our army still massively uses front-loading guns. Changing a front-loading gun to a front-loading rifled gun is much faster than regenerating a rear-loading gun, right? Before a large number of rear-loading guns were equipped with troops, it was necessary to use front-loading rifled guns for the transition! ”

"Thank you, Dashuai, the student understands!" Xue Fengzuo arched his hand and replied.

Wang Yu said with a smile: "Yes, at present, it is necessary to manufacture this kind of bullet in large quantities, and the smoothbore gun is gradually engraved with rifling and changed to rifled guns!" By the time of our army's northern expedition, there will be at least 5,000 rifled gunners, and there will be no need for stragglers, and rifled guns can be used in formation, how powerful is that? ”

Dai Zi anxiously asked: "So when will our rear-loading guns be mass-produced?" ”

"There's no need to rush!" Wang Yu said with a smile, "You can save the production equipment and assembly line of the rear loading gun, and then put it into mass production!" But there's one more important thing, you father and son must get the metal cartridge bullet out as soon as possible! And metal cartridge bullets must use smokeless new gunpowder! ”

"Metal cartridge bullets?" Dai Zi was stunned.

"Yes!" Wang Yu nodded, "Paper cartridge bullets are loaded after the gun, and they are also transitional weapons!" Only metal cartridge bullets are the future trend! With metal cartridge bullets, you can make a gun with a faster rate of fire! It is even possible to build a gun that fires continuously! ”

The group walked back to the exhibition room of the research institute, Wang Yu pointed to a Thunderbolt fire box car placed in the middle of the showroom, and said to Xue Fengzuo, Dai Zi and others: "This Thunderbolt fire box car has a very fast rate of fire, and can fire 100 rounds of bullets in a row. However, the principle of this weapon is that a hundred barrels are embedded in the wooden plank, and the weight of the gun is very heavy, and it is difficult to reload, and after firing once, it takes several people to lift the wooden plank with the inlaid barrel. In addition, the firing range of such a gun is too close, and if a hundred barrels are rifled, then how much will it cost? ”

"So what does the handsome mean?" Dai Zi asked.

"As long as we can make metal cartridges, we can make a gun with six barrels, all six barrels are engraved rifling, and the gun has a swing handle behind the gun, and when the shooter shakes the handle, the barrel rotates and the bullet is loaded at the same time, so that it can be fired continuously." Wang Yu explained to Dai Zi.

After that, Wang Yu asked people to take pens and paper, and drew a sketch on the paper: "You see, this kind of shaking handle is also linked to the bolt through gears, and while shaking the handle, the barrel rotates, loads the bullet, and throws the cartridge case at the same time. To accomplish this, metal cartridge casings and smokeless gunpowder had to be made. ”
