　　 It is not difficult to make up for these two shortcomings of the Dreiser rifle.

　　 The first thing that needs to be changed is to install paper shell ammunition.

　　Dreiser invented this fixed-packed paper shell ammunition. The detonator, that is, the flash hider, is installed behind the warhead’s **** and on the top of the propellant’s head.

　　 Although the bullets of later modern rifles are fixed-loaded metal ammunition, the principle is actually the same as that of fixed-loaded paper shell ammunition.

　　The propellant is placed in the shell, and the top of the shell is inlaid with the warhead. When the propellant in the shell is ignited by the flash cap, the explosive propellant will shoot the warhead out to complete a firing.

　　 is also the process of completing a firing of the paper shell ammunition.

　　 The difference between the two bullets is the material of the shell.

　　 But no matter what kind of ammunition, it must be fired by the flash cap to ignite the propellant. However, the bullets used in later modern rifles, the flash hider is at the bottom of the cartridge case. And for the paper shell bullet developed by Dreiser, the flash hider is between the propellant and the warhead.

　　Modern bullets, when the firing pin hits the flash hider at the bottom of the bullet, the propellant will explode in the shell, which has no effect on the firing pin. For this paper shell bullet developed by Dreiser, the tip of the firing pin needs to pass through the propellant to fire the flasher. In other words, when the propellant of this paper shell bullet is detonated, the first one to be injured by the deflagration of the propellant is the needle.

　　 A barrel that is so thick cannot withstand the high heat and pressure generated when the propellant explodes, let alone a very thin firing needle.

　　 Therefore, in order to make up for this defect, the first thing to change is the design of the paper shell bullet.

　　 With the technological power of this era, it is simply impossible to produce that kind of copper shell bullets or copper-clad steel bullets. In fact, even in the 21st century, there are fewer than 30 countries in the world that can produce copper bullets, and there are only 13 countries that can produce shells and bullets at the same time!

　　 So, bullets with fixed metal shells are not so easy to get out. Shixiong suspected that even if he had produced the anti-aircraft gun, he would probably not be able to produce bullets with metal shells...

　　 Although this is a bit exaggerated, there is no doubt that the production of bullets with metal shells is absolutely impossible in this era. Then, the production of paper bullet shells is a must.

　　 Compared with metal bullet shell bullets, the production process of paper bullet shell bullets is not so difficult. The bottom is inlaid with a flash hider cardboard tube and a fixed amount of propellant, and a round-head cylindrical lead bullet is inserted in the front to complete a paper-shell bullet. Even if it is made by hand, one person can make a lot of bullets a day.

　　If you use a rotating rear-pull gun machine, because of the processing technology of this kind of machine, the confidentiality of the guns produced at the beginning is not good, but it is always much better than the rotation locking mechanism of the Ferguson rifle.

　　 In this way, the amount of gunpowder that is fixed will also be reduced a lot.

When using the Saint Etienne rifle seized from the French in the past, the ratio of black powder was not correct, so the amount of propellant required for each bullet was about 123 grains, which is about 8 grams. about. The Ferguson rifle used by the expeditionary army now uses black powder with a perfect formula as the propellant, so the propellant quantity per bullet is about 100 grains, which is about 6.5 grams.

　　 And if you use a rifle with a revolving back-pull bolt action, then the propellant contained in the paper shell of each bullet can be reduced to 70 grains, which is about 4.55 grams!

　　 This kind of charge is 30% less than that of the Ferguson rifle, but the effective range of the bullet has increased by three times!

　　 This is the consequence of technological progress.

　　 The charge of one bullet is 2 grams less, and the charge of 100,000 bullets is less than 200 catties!

　　 Don't underestimate this number, 100,000 bullets cause trouble? Calculated according to the intensity of a single-force war, 100,000 bullets are not even enough for two thousand people to fight a low-intensity battle...

　　The amount of ammunition is saved. Not only can the logistics supply be easier, the soldiers can also carry more bullets.

　　The most important thing is that by attaching the flash hider to the bottom of the paper shell bullet, the firing needle can not only shorten the length, but also no longer suffer direct damage from the propellant during firing, and the life of the firing needle will be much longer.

　　 Stone bears don’t even know why Dreiser developed such a paper-shell bullet back then. Is it so difficult to inlay the flash hider on the bottom of the cartridge case? Obviously, the difficulty of inserting the flash hider on the bottom of the cartridge case is not much greater than the difficulty of inserting it on the bottom of the warhead.

　　 solves the bullet problem, and the needle shot problem will be solved by the way.

　　 And because the flash hider is inlaid at the bottom of the cartridge case, the firing pin does not need to pierce the propellant to fire the flash hider, so the firing pin can be designed not only to be shorter, but also to be thicker, which prolongs the life of the firing pin many times.

　　 These living stone bears just know the principle. If you ask him to do it by himself, he must not be able to do it.

　　 But it doesn’t matter, there are four great alchemists!

　　 These four guys are getting more and more capable now. They even have a boring machine for boring rifle barrels. It should be no problem to make a bullet machine. What Shixiong needs to do is just to tell them the working principle of this rotating back-pull gun, and then these four guys will work together to use the paper shell bullets that meet the requirements and the new rifle gun in the shortest time. from!

　　 Ishikuma has no doubt about this.

　　 As for how to reduce the problem of air leakage, this is not a difficult task.

　　 Although due to the limitation of processing technology, it is still impossible to produce the excellent airtight action of the later modern rifles, but there is no way to solve the air leakage of the action.

In the original historical time and space ~www.wuxiaspot.com~ 90 years later, the Frenchman Anthony Alfonso Chaseppo will develop a rear-loading gun, which is named "Chaseppo Rifle" .

The working principle of this rifle based on the Dreiser rifle is no different from that of the Dreiser rifle. It is just that when Xia Sebo developed this rifle, he fully considered the defects of the Dreiser rifle and fixed the paper shell with bullets. The primer was on the bottom of the shell.

　　 Ishikuma's design plan to transform the Dreiser rifle was actually derived from the design of the Xiasaibo rifle.

　　 It’s just that the most convincing innovation of the Xiasaibo rifle is the use of a rubber air-locking sleeve to prevent gas leakage on the surface of the bolt, which greatly reduces the air leakage of the bolt.

Although this method is not perfect, because the rubber shrinks and hardens due to the action of gas after each shot, and eventually loses its effect, and needs to be replaced at any time. However, compared with the firing pin design of the Dreiser rifle, which is always in deep water, this The design is undoubtedly much more perfect.

　　 And under the current situation, the design of the Xiasaibo rifle is undoubtedly more in line with the requirements of the stone bear.

　　 After all, long before Columbus discovered the New World, Indians living in Central and South America had begun to use natural rubber. It is not difficult to obtain natural rubber...
