　　 Needle-punched rear-loading rifled gun is also called rotary rear-pull bolt rifle.

　　Because this is the world's first rifle with a rotating back-pull action, this rifle will have three names.

The first name is naturally a needle-punched rear-loading rifled rifle, and the second name is to commemorate that this rifle is the world’s first revolving rear-pull bolt rifle, so this rifle has the second one. first name.

　　 As for the third name of this rifle, it is also famous, that is the Dreiser rifle.

　　 On the 11th and 20th of 1787, in the small town of Somerdane in the electorate of Mainz, a baby boy who was waiting to be fed was born in a locksmith's family.

The birth of 　　 baby boy brought endless happiness to this ordinary family. As a locksmith father, he hopes that the newly born boy can take over his clothes and become a locksmith in the small town. After all, in this turbulent era, although the income of locksmiths is not very high, it is still a stable industry. If children can learn their own crafts in the future, at least they don't have to worry about eating and drinking.

　　 It's just the father of the child who didn't expect that his son did not inherit his locksmith mantle when he grew up, but plunged into the work of weapon research and development. When the child grew up to 22 years old, he went to a French gun factory and spent five years experimenting with several rear-mounted rifled guns.

　　 But it is a pity that these breech guns tested by this boy who has grown into an adult youth have not achieved much success.

　　 The failure did not discourage the young man. He then returned to his hometown of Semelda, and opened a factory in his hometown, using the flash hider technology he just developed to produce flash hiders.

The production of Flash Hider has brought him huge benefits, but he is not obsessed with huge benefits, because he always has a desire in his heart to develop a real rifle that can surpass any rifle in the world. Breech gun.

It is with the support of this belief that he has not stopped the research and development of the breech gun since he opened his own flash hider processing factory in 1814. It took him a full 26 years, and finally in 1836. Completed the design of the whole needle gun with ammunition loaded from the back!

　　 However, at the time, rifles were loaded with ammunition from the muzzle. Loading ammunition from the back is undoubtedly a very "non-mainstream" approach. As if the Ferguson rifle developed by Lieutenant Ferguson was ridiculed by the British, the Ferguson rifle, the world's first breech gun, was finally dead.

In those days, rear-loading guns were very unpopular. Even when a Swiss military delegation visited Prussia, the Swiss general who reviewed the Prussian rear-loading troops walked and shouted: "Eating with your mouth is noble. (Pointing to front-loading guns), Swiss shooters have never been humble enough to use a'enema gun' (rear-loading guns) loaded from the rear to shoot."

　　 This shows how unwelcome it was to install guns at the time.

　　 However, the Prussian government recognized the superiority of this "non-mainstream" rifle, so the government immediately acquired this invention and used it as the most advanced secret weapon for secret development.

　　 In 1841, after the Dresser solved several key technologies of the needle firing rifle, the Dresser rifle was immediately adopted by the Prussian army and installed under the name M1841.

　　 This is the origin of the famous Dreiser rifle!

　　 When Shi Xiong decided to switch to the expeditionary rifle, the first thing he thought of was this famous Dreiser rifle.

Compared with the rotating locking mechanism of the Ferguson rifle, the rotating back pull bolt used by the Dreiser rifle is undoubtedly much more advanced, and the design of this rotating back pull bolt has also become the starting point of modern rifle bolts. . It is no exaggeration to say that, including the era before the Shixiong crossed, the rifle guns used by the armies of all countries in the world were almost all extended from the basis of this rotating rear pull gun.

　　 Like Da Mingding’s Mauser rifle, Enfield rifle and Mosin Nagan rifle, its bolt mechanism design principle is based on this rotating rear pull bolt mechanism designed by Dreiser. This shows the status of this bolt in the history of rifles!

　　 In fact, the Dreiser rifle is not the world’s first mass-equipped rear-loading gun. The Ferguson rifle came out 70 years before the Dreiser rifle appeared. The M1819 rifle produced by the Americans in 1819, also called the Hall rifle, produced as many as 20,000.

It’s just that even if the Hall rifle came out, American soldiers at that time were still accustomed to using front-loading guns. This led to the production of as many as 20,000 Hall rifles in military factories, but most of these rifles were in existence. The original factory state.

　　 The reason why the Dreiser rifle is so famous and known as the world's first real rear-loading gun is because this rifle with a rotating rear-pull bolt has been proven on the battlefield.

　　Whether it is the Pudan War or the Austrian War, the strength of the Dreiser rifle is well known. Especially in the Prussian-Austrian War, Prussian soldiers armed with Dreiser rifles defeated the very powerful Austrian Empire in just seven weeks.

　　 Like the Ferguson rifle, the stone bear, a puppet army fan from later generations, wanted to replace the expeditionary army rifle. Naturally, he thought of this rifle that will only shine in a hundred years.

　　 After all, whether it is a revolving back-pull gun or a fixed ammunition, this is the future development direction of firearms. Before the appearance of Gauss and energy rifles, as long as the guns were powered by chemical energy, they were almost all developed in this way.

Although a rifle with a rotating rear-pull bolt action, the requirements for the barrel will become very high. The cast barrel used before can be used at a rate of fire of six or seven rounds per minute, but when the rate of fire reaches At twelve rounds per minute, the cast barrel can no longer be used, otherwise it will easily explode.

　　 Fortunately, thanks to the efforts of the four alchemists, a machine tool for boring barrels has been developed. Although the efficiency is still a bit low, the lack of efficiency can be compensated by quantity. The barrel problem is not the main problem.

　　 Although the Dreiser rifle is great, it is not without its shortcomings. This shortcoming is mainly due to the design defects of the ammunition and the firing needle.

The 　　 Dreiser rifle adopts the firing principle of "acupuncture". This firing principle is to pack the projectiles, detonators and black powder in a cylindrical paper shell, which is a fixed paper shell bullet. But the detonator is not installed in the rear of the shell, but in the middle of the bottom of the projectile.

When the trigger is pulled ~www.wuxiaspot.com~ the force of the spring releases the slender firing needle, which pierces the bottom of the shell of the gun cartridge from the front end of the bolt, and moves forward until it reaches the detonator at the bottom of the projectile. Detonate it, and then ignite the black powder in the paper shell to complete a firing.

　　This firing method is a great way, but in Dreiser's design, the firing needle of this bolt has a fatal problem, that is, it is too long. Because the flash hider of the fixed paper shell bullet developed by Dreiser is at the front end of the propellant, the firing needle must be designed to be longer, so that the propellant that penetrates the back of the paper shell can hit the front when it is fired. On the flash hider.

　　 But then the problem comes, the wrong length of the firing pin will make the firing pin often contact the hot gunpowder and cause damage to the firing pin. If it is not a big problem in normal times, but if on the battlefield, the soldiers are about to shoot, and the firing needle suddenly breaks, wouldn't it be fatal?

　　 And the Dreiser rifle and the Ferguson rifle have the same shortcomings, that is, the air tightness of the breech is very poor, and the gunpowder gas emitted will interfere with the shooter's aim, and even burn the skin in serious cases.

　　 These are the shortcomings of the Dreiser rifle.

　　Since it is necessary to change the outfit, it is necessary to make up for all these shortcomings, so that the rifle that the expeditionary army changes into a rifle with few shortcomings. At the very least, there can be no such major fatal flaw is...
