What excites Wang Yu the most is not the new rifle, but the bullet in the bullet box. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info opened the bullet box, and it was full of yellow, orange and orange bullets, which were metal bullet shell bullets!

Metal cartridge bullets, which means that modern new firearms are about to be born! With metal cartridge cartridges, there is a bolt-action magazine rifle that can be used to hold bullets in the magazine, that is, a rifle called a fast gun in the nineteenth century, which can hold five rounds in the magazine, and the bolt can be pulled once to complete the bolt reset, throw out the cartridge case, and then pull the trigger, and then pull the bolt to throw out the cartridge case, and so on, until the bullet in the magazine is finished, and then open the cover plate and press in a new row of five bullets, this gun has a much faster rate of fire than a single-shot rifle.

Wang Yu picked up the gun, pulled the bolt, and the magazine cover opened, revealing the chamber inside. He took a yellow-orange bullet from the cartridge, stuffed it into the chamber, and pushed the bolt forward, closing the cover. Then Wang Yu picked up the gun, aimed at the target a hundred paces away and pulled the trigger.

There was a "bang" of gunshots, and the muzzle of the gun flashed, spewing out light blue gunsmoke. However, because Wang Yu was not familiar with the performance of this gun, this gun failed to hit the target.

Wang Yu pulled the bolt of the gun, and the grappling hook in the cover of the magazine pulled out the bullet case, and automatically threw it out, and the cover opened, revealing the chamber inside. He took out a new bullet, stuffed it into the chamber, and then pushed the bolt and the cover closed. Then he picked up his gun, aimed at the target and pulled the trigger.

"Bang" a gunshot rang out, and this time the bullet hit the target accurately.

This new rear-loading rifle is not actually a later magazine rifle, but a single-shot rear-loading rifle that has to be reloaded every time it is fired.

Although in history, Dai Zi invented the Lianzhu gun that can be fired continuously, but according to Wang Yu's prompt, when making metal cartridge shells and reloading guns, he did not create a magazine rifle that could hold five rounds, and it was still a single-shot rearloading rifle that needed to fire one round and one round.

The reason for this, in addition to the much more complex structure of the magazine rifle, is also the problem of the caliber of the bullet. The caliber of this rear-loading rifle reached 10 mm, and the bullet was much larger than that of the later 7.62 mm, 7.7 mm and 7.92 mm rifles.

But Wang Yu is already very satisfied with this rear-loading gun, the increase in the rate of fire of this gun is only one aspect, after the metal cartridge bullet, it is already very close to the birth of the machine gun.

Even Xue Fengzuo, who had always recommended the use of a Mini bullet rifle before, was full of praise for this metal cartridge rifle: "It's still the prince's foresight!" Breech-loading rifles could be developed to metal cartridges, not only did the reloading speed increase, but the range was not even closer than that of front-loading rifled guns, and this gun could shoot exactly two miles away. ”

Wang Yu asked, "Mr. Xue, this fan asked you to co-design the hand-cranked quick grab with them, has there been a result?" ”

Xue Fengzuo shook his head: "The structure of that thing is too complicated, and the students tried several times, but they all failed. However, the students also came up with a new weapon, which was made thanks to metal cartridges. Without metal cartridges, bursts would not have been possible. ”

"Then hurry up and take the clan to see the new weapons you made!" Wang Yu said overjoyed.

"Please come with the students." Xue Fengzuo said.

Xue Fengzuo took Wang Yu and others into a laboratory, and when they entered the laboratory, Wang Yu saw at a glance a mechanical device without a shell placed on the table, which was a magical machine composed of various parts such as gears, connecting rods, push rods, and shaking handles. With his own experience, Wang Yu could see at once that this was a bolt equipment for firearms.

Wang Yu took a closer look, and saw that the structure of this bolt was very complicated, and there was a swing handle behind the bolt, and the direction of the swing was also marked. As long as you shake the handle clockwise, it will drive the gears inside to turn. The gears drive a cam similar to that used on steam engines, pushing the connecting rod back and forth as the cam turns. The linkage is connected to the grappling hook, which appears to be used to throw the cartridge case, and the spring is compressed backwards to push the firing pin to strike the primer of the cartridge case. There is also an ejector rod, which appears to be used to push a bullet into the chamber.

However, what made Wang Yu feel strange was that this bolt had two sets of connecting rods and push rods, as well as two sets of grappling hooks.

"This is a double-barreled gun, and as long as the handle is shaken, the two barrels are fired in turn. It's just that the barrel hasn't been connected yet, it's just being tested. Xue Fengzuo said.

Mei Wending took a metal box filled with bullets from bamboo shells and wooden warheads.

Wang Yu looked at the box carefully, it was obviously a bullet magazine, and there was a spring inside to push the bullet out, but the top of the bullet magazine was an arc, just stuck the bullet, so that the bullet would not pop directly from it. The two sections above the magazine are empty, and the bullets can be stuffed in from the back or pulled out from the front.

Mei Wending turned the magazine upside down and stuck it above the bolt. Then Xue Fengzuo shouted: "Don't stand in the way, you won't pay if you are injured!" ”

Out of curiosity, the person standing in front of the bolt hurriedly got out of the way.

Xue Fengzuo shook the handle, only to see that the gear in the bolt rotated, driving the cam to rotate, and the cam drove the connecting rod again, and a bullet pusher rod pushed forward, pushing the bullet in the magazine out and into the chamber. The push lever moved forward to the top and began to move backwards, a piece of iron stuck in the spring was released, and the spring bounced forward with the firing pin, and the firing pin pierced into the bamboo barrel cartridge case, hitting the wooden bullet bullet, and the bullet flew out under the action of the spring.

After the bullet flew out, with the shaking of the handle, a grappling hook moved backwards, grabbed the bamboo barrel cartridge case, and threw it out. The connecting rod then compresses the spring backwards, and a pusher lever pushes forward, pushing a new bullet into the chamber. Then the firing pin strikes the bullet, and the wooden bullet flies out under the action of the spring.

"Very clever design! As long as the bamboo barrel wood bullet is replaced with a real bullet, and the firing pin hits the primer, the propellant inside the bullet can be ignited, and the bullet will be fired. Wang Yu said with praise.

Although the rate of fire of this hand-cranked double-barreled weapon was not as fast as that of a hand-cranked multi-barreled machine gun, it was much faster than the later bolt-action rifles.

"As long as you add the barrel and the casing of the bolt, it is a weapon that can be fired continuously." Wang Yu said.

This hand-cranked double-barreled gun does not have a slow rate of fire and can fire more than a hundred rounds in a minute.
