Chapter 372 (2/2)

Compared with Ferguson rifle's rotary locking mechanism, Dreiser rifle's rotary back-pull mechanism is undoubtedly much more advanced, and the design of this kind of rotary back-pull mechanism has become the starting point of modern rifle. It is no exaggeration to say that in the era before the stone bear crossing, almost all the rifles and guns used by the armies of all countries in the world were extended from the basis of this kind of rotary back-pull gun.

Like Daming Ting's Mauser rifle, Enfield rifle and moshinagan rifle, the gun design principle is based on Dreiser's design of this rotary back pull gun. We can see the position of this gun in rifle history!

In fact, Dreiser rifle is not the world's first large-scale equipment after the gun, Dreiser rifle appeared 70 years ago, Ferguson rifle came out. The m1819 rifle, also known as hall rifle, produced by the Americans in 1819, produced as many as 20000 rifles.

However, even though hall rifles came out, American soldiers at that time were still used to using front loaded guns, which led to the fact that even if up to 20000 hall rifles were produced in military factories, most of them were in the original factory state.

The reason why the Dreiser rifle is so famous and known as the world's first real afterloading gun is that this rifle with a rotary back-pull gun has been proved in the battlefield.

The strength of the Dreiser rifle is well known in both the putdan war and the poggot war. Especially in the Prussian War, the Prussian soldiers with Dreiser rifles defeated the very powerful Austrian Empire in only seven weeks.

Like Ferguson's rifle, stone bear, a puppet fan from later generations, naturally thought of this rifle which will shine in a hundred years when he wanted to replace the expeditionary rifle.

After all, whether it's rotary back-pull guns or fixed ammunition, this is the development direction of guns in the future. Before the appearance of Gauss and energy rifles, almost all guns powered by chemical energy developed in this way.

Although the rifle with rotary back-pull gun machine has high requirements for barrel, the former cast barrel can be used at the firing rate of 67 rounds per minute, but when the firing rate reaches 12 rounds per minute, the cast barrel can not be used, otherwise it is easy to explode.

Fortunately, with the efforts of four alchemists, the special boring machine for the barrel has been developed. Although the efficiency is still a little low, we can make up for the lack of efficiency by quantity. The barrel problem is not the main problem.

Although the Dreiser rifle is great, it is not without shortcomings, which mainly comes from the design defects of ammunition and firing needle.

The firing principle of ”needling” is adopted in the Dreiser rifle. The firing principle is that the projectile, primary explosive and black powder are all packed in a cylindrical paper cartridge case, that is, the fixed paper cartridge. However, the primary explosive is not installed in the rear of the shell, but in the middle of the bottom of the projectile.

When the trigger is pulled, the force of the spring releases the slender needle and penetrates into the bottom of the cartridge paper shell in the barrel from the front end of the gun. It goes forward until it reaches the detonator at the bottom of the cartridge and detonates it. Then, it ignites the black powder in the paper shell to complete one shot.

This firing method is a great way, but in Dreiser's design, there is a fatal problem in the firing needle of this gun, that is, it is too long. Because the cap of the fixed paper shell bullet developed by Dreiser is at the front of the propellant, the firing pin must be designed to be longer, so that it can break through the propellant at the back of the paper shell and hit the cap at the front.

But this is the problem, the wrong length of the needle will make the needle often contact the hot powder and cause damage to the needle. If it's not a big problem at ordinary times, but on the battlefield, when the soldiers are about to shoot, the needle suddenly breaks down, isn't it fatal?

And Dreiser rifles and Ferguson rifles have the same disadvantage, that is, the air tightness of the breech is very poor, the gunpowder gas will interfere with the shooter's aiming, and even burn the skin seriously.

These are the shortcomings of the Dreiser rifle.

Since we need to change our clothes, we must make up for all these shortcomings, and make the rifle changed by the expeditionary army a rifle with few shortcomings. At least there should be no such fatal defect
