In fact, don't talk about the Franc machine of the year, even the revolver of the 21st century, the gun used for many years is aging, and when firing, if you put your finger between the gaps in the revolver, the gunpowder gas spewed out can cut off your finger!

Therefore, when the Franc cannon was fired, the gunner would stand in a position where it would not be sprayed by gunpowder gases. The same goes for this rear-loading rifling run www.biquge.info, which is not well sealed enough, and when firing, the gunner should avoid the gaps where the gas leaks out to avoid being harmed by the gunpowder gas.

Walking into the gun factory, I saw that the water drawn down from the barrage drove all kinds of machinery, making a violent impact sound, and the workers in the factory were busy in an orderly manner. The blast furnace burns, the molten iron is poured into a mold, and after cooling, the cast barrel and barrel are sent to a hydro lathe for further processing.

Now the production of musket barrels, also adopt the method of one-time casting, which can save a lot of time, and then the cast barrel is then hammered by hydraulic machinery while hot, and the inner wall is polished and polished to ensure that the inner wall of the barrel is smooth.

As for rifled guns, they are still produced by manual lathe rifling, because the strength and speed of hydraulic machinery are not easy to master, and the precision barrel of rifling can only be built by human hand.

There are also some flintlock muskets converted into rifled guns, a carefully selected batch of the best quality barrels, placed on a manual lathe, and the worker shakes the handle to pull out the rifling of the gun.

At the current rate of production, 100 rifled gun barrels can be made per month, but because the technology of mini bullets is not yet mature, rifled guns are slower to reload, so they cannot be popularized on a large scale. Looking at the Thunderbolt bolt again, although the short barrel processing is much simpler, the structure of the Thunderbolt bolt is too complex, and it cannot be mass-produced before mechanized mass production, and can only be used as the equipment of generals and a few elite soldiers.

In addition, because of the surprise attack on the Horqin tribe, the double-barreled long gun was well received among the cavalry, this weapon is powerful, can be fired twice, and because the barrel is not particularly long, it can be ridden and shot on horseback, so it is very popular with cavalry.

But most of the double-barreled guns were smoothbore guns, and only a few rifled guns, after all, rifled guns were too slow to load. At present, the technical personnel of the gun factory are working on the development of a new type of rear-loading double-barreled rifled gun, the barrel of the double-barreled gun is relatively short, and the processing technology of a single barrel is lower than that of a long-barreled rifled gun, and the number of production can be increased. The difficulty lies in the complexity of the rear-loading bolt, the Eucommia ulmoides glue used to solve the problem of air leakage is not durable, the service life is too short, and the price of rear-loading gun bullets is too high.

With the current technology, it is not possible to produce metal cartridge shell bullets at all, in fact, metal cartridge shell bullets are also a high-tech, and in later generations, a large country that can build atomic bombs will not be able to produce bullets!

Well, that big country can build an atomic bomb, and it can also build what is known as the best aircraft and tanks in the world, of course, the research cycle is very long, an airplane can not go to the sky after 30 years of research, and a tank has been studied for 30 years and their army still does not dare to use it, which shows how patient their country is, how hard they work, and of course they disdain to produce bullets.

With the current technology, it is temporarily impossible to produce metal cartridge shell bullets, so the bullets of the rear loading gun are also paper cartridge bullets, even so, the price of the rear loading paper cartridge bullet is very expensive, and because of the problem of sealing, it is not possible to manufacture the rear loading rifled gun with a long barrel for the time being, and these problems need to be solved, only rubber and steam engines.

The double-barreled long gun, because the barrel is shorter, can take the rear-loading technology.

Wang Xinyu took a sample gun and looked through it a few times in his hand.

The worker on the side said: "Lord, the butt of this fire gun can be bent, and after the butt is bent, the chamber will be exposed, and the bullet can be stuffed in from behind, and then the butt can be straightened." ”

According to the worker's guidance, Wang Xinyu grabbed the barrel with one hand, pressed the butt with the other, and pressed hard, and the butt and the barrel formed an angle of 90 degrees, revealing the breech behind the barrel. He picked up two paper cartridges, stuffed them into the barrel, and pressed the butt again, and the double-barreled long gun returned to firing.

The "bang" musket roared, and two bullets were fired at the target eighty paces away.

"Twenty rings!" The target announcer reported the results of the shooting.

"This kind of firearm can penetrate the poplar in 100 steps, but the cost of this firebolt is too high, and it is difficult to train the horseback rider who can wear the poplar in 100 steps." Dai Cang introduced to Wang Xinyu.

Wang Xinyu said with a smile: "Archers can also penetrate Yang in a hundred steps, but how many archers can there be in Yang in a hundred steps?" Training an archer with a hundred paces is probably several times more difficult than it is for us to build a firearm and train a marksman, right? So even if it's a one-to-one exchange with the archers, we still have a big advantage! As long as those few sharpshooters die, the rest are not just shot and killed? ”

Compared with muskets and bows and arrows, the main reason is that the cost of human training is disproportionate, and it is much easier to train a sharpshooter than to train a sharpshooter, not to mention that there are long-barreled rifled guns that can accurately snipe the opponent's sharpshooters.

To popularize the rear loading gun in large quantities, it is mainly limited by bullet technology.

In fact, if the bullet technology is improved and the Mini bullet can be created, the rate of fire of the front-loading rifled gun can be greatly improved, and the loading speed is even faster than that of the smoothbore gun, and a large number of smoothbore guns can be pulled out of the rifling to replace the old smoothbore guns.

Walking into the experimental field behind the gun factory, what caught Wang Xinyu's eyes was a new-style small steam rail car. This steam trolley is not big, and there is a circular narrow-gauge track with a diameter of 200 steps laid in the test site, which is a very narrow narrow gauge, which can also be called an inch-gauge railway, with a gauge of about two feet, that is, about 650 millimeters.

The gauge of the inch-gauge railway is less than half that of the standard gauge, and the width of the car is also very narrow, only five feet wide. A small steam locomotive parked on the track has a carriage hanging behind it, this kind of car is very simple, it looks like the later Jiayang train, the body is very short, much smaller than the standard gauge rail carriage currently running in Qiongzhou.

Seeing Wang Xinyu coming in, Xue Fengzuo, Song Shihui, Song Shiyi, Xu Zhengming, Mei Wending, Dai Zi, Liu Feng and others hurriedly greeted him.

"What about Dean Song?" didn't see Song Yingxing, Wang Xinyu asked with concern.

Song Shihui replied: "My father is old and sick in bed, and it has been two days. ”

Hearing Song Shihui's answer, Wang Xinyu felt a little uncomfortable in his heart, maybe Song Yingxing's life was almost over, after all, he was an eighty-year-old man! After a while, Wang Xinyu slowly spoke: "After a while, this fan will go to see Ling Zun, his old man is old, so don't fight so hard!" Take more rest. ”

Song Shihui arched his hand and said: "Lord Wang, my father's lifelong wish is to be able to combine Taixi's advanced technology with Oriental technology to make my Ming Dynasty stronger!" Now that wish is coming true! (To be continued.) )
