Chapter 306 Bullet Transformation

Bah!
...

Liu Xinqi's answer was the sound of a gunshot, and the humanoid target two hundred steps away visibly shook.

The soldier hiding behind the sandbag pulled up the target and ran towards this side.

"How is this possible!!" Liu Xinqi said in shock. He knew best about the weapons he participated in the design, development, and manufacturing of. The "Xinghan Type [-] Flintlock Musket" has an accurate shooting distance of up to a hundred steps.Two hundred steps, if thrown, the bullet may fly, but it will definitely have no lethality at all.

"This is considered close. We have tested it and the accurate shooting distance has reached [-] steps. It is still lethal at [-] steps." Cui Wu replied.

The precise shooting range of 450 meters and the killing range of 600 meters have already reached the standards of a sniper rifle! !

Does this gun have "excellent" attributes, or has its fantasy attributes polluted the world?

[This is a flintlock musket from the black powder era. 】

Liu Xinqi was a little confused and confused, and he said without thinking:

"It's impossible!"

At this time, the target was just delivered. Cui Wu took it and handed it to Liu Xinqi for inspection. There was a hole in the right chest of the human-shaped target. The target was a wooden board with an inch back. Being able to shoot through a board of this thickness would be enough to kill an unarmored target at the same distance. .

"How is this done?" Liu Xinqi still couldn't believe it. He asked the soldier to hold the weapon in his hand and check it carefully. It was indeed a standard "Xinghan Type [-] flintlock musket" and had not undergone any magic modifications.

"Let him tell you." Cui Wu pointed to the gunman who had demonstrated shooting just now.

Liu Xinqi raised his head and looked at this man. He had an ordinary appearance, a Chinese character face, and his facial features were not very three-dimensional. Among the crowd, he was the kind of person who could be forgotten after just one glance.But this person's eyes are very bright, and his small single-lidded eyes are bright and lively, which makes this person's overall face look much more energetic.

He should be about 1.6 meters and a half tall. He is not short in this era, but he is not too tall either.

The physique was quite strong. Liu Xinqi could see that he had not attached a military card. To have such a good physique, he either had a good family background or had good training after becoming a soldier.

"Hello, Alliance Leader, my name is Shao Zhen, Dao Kou Shao, true and false."

This man has a good personality. The Xinghan League has grown to its current scale, and Liu Xinqi's power has become more and more powerful. There are few newcomers who can be so free and easy in front of Liu Xinqi.

"This gun shoots so far and so accurately, is it because of you?"

"As Battalion Commander Cui said, it is indeed a coincidence." Shao Zhen said, not knowing that Cui Wu had been promoted to regimental commander.

"Tell me in detail."

After Shao Zhen's introduction, Liu Xinqi knew the real reason.

The bullets of the "Xinghan Type [-] Flintlock Musket" are cylindrical round-head bullets designed by Liu Xinqi. There are pits at the tail of the bullet, and the edges of the pits are very thin.It is expected during the design that after the propellant explodes, the edge of the pit at the end of the warhead will expand and stick to the wall of the barrel. The three spiral riflings in the barrel will cause the warhead to rotate. The rotating warhead will shoot harder after it exits the barrel. farther, with a straighter trajectory and greater destructive power.The design was very good at the time, but due to material constraints, the results were not very satisfactory.

First of all, because the gunpowder is black powder, the power of the explosion is naturally limited, and the kinetic energy given to the bullet is also small. Even if the seal is very good, it cannot shoot as far as the rifles of later generations.

Moreover, the sealing performance is not as good as Liu Xinqi imagined. When muskets were first invented in later generations, lead bullets were used. Lead was chosen as the projectile material because lead is a relatively soft metal among metals. After the invention of rifled guns, Lead fits the rifling better and spins better.Moreover, lead is softer than iron, and it will wear less on the rifling.

For Xinghan League, lead was too expensive in this era, so Liu Xinqi finally chose iron as the projectile material.

In order to minimize the wear of iron bullets on the rifling, we chose the highest purity iron that Xinghanmeng's current technology can purify, because pure iron is softer than iron containing carbon.

Everything has advantages and disadvantages, because the edges of the crater of iron bullets are too soft. As a result, after the propellant explodes, most of the time it does not all expand outwards as designed. Some parts of the edges curl inward, and some edges are damaged by the impact of the explosive explosion. There is no change at the bottom, and some edges are directly broken.

The end result is: the sealing is improved, but it is not completely sealed.It does not fit the rifling closely enough, resulting in a low rotation speed.

The round-head cylindrical warhead does shoot farther and more accurately than the round warhead, but it is only about twice as far.

Liu Xinqi always thought that this problem could only be solved after the breech-loading gun came out. Unexpectedly, Shao Zhen solved it with a small piece of cork.

Gu Shaozhen said: He once played with a bullet, and suddenly he had a whim and stuffed a small piece of cork into the pit at the bottom of the bullet. Then he discovered that when shooting, the bullet would shoot very far and the accuracy would be much better. .

After Shao Zhen's small improvement was discovered by Cui Wu, it was fully promoted in Cui Wu's infantry camp. Finally, he selected the gun that consistently shoots the farthest and most accurately, and demonstrated it to Liu Xinqi today.

"That is to say, not all guns are so powerful. Only this gun can shoot farther and more accurately with improved bullets, and it also has the bonus of Shao Zhen's shooting talent?" Liu Xinqi asked.

"Indeed, this one has the highest degree of improvement. Of course, using improved projectiles, the firing range of other guns will increase by [-]% to one and a half times to varying degrees. And after using improved projectiles, the range and accuracy of the gun will increase It has become much more stable, unlike before, sometimes far and sometimes near, always on time but not right." Cui Wu introduced.

"It's amazing."

Liu Xinqi took over an improved projectile with cork stuffed at the bottom and praised it. His soul came from later generations, and he knew that many inventions were just minor improvements, but they could greatly improve efficiency and performance.

Liu Xinqi looked at the projectile and estimated that his principle was basically the same as Liu Xinqi's design idea, except that with the cork in the pit, Liu Xinqi's design goals would be better achieved.

In order to make the projectile enter the rifled barrel better and more smoothly, the diameter of the projectile manufactured by Xinghanmeng is smaller than the inner diameter of the muzzle. Because the industrial accuracy is low, air leakage will occur during shooting, which will lead to the various previously mentioned All kinds of questions.

Now with this small piece of cork at the bottom of the pit, these defects can be perfectly solved.

After the propellant explodes, the cork is instantly ignited. The cork burns and expands to spread out the thin iron sheet on the edge of the pit, so that the bottom of the projectile completely fits the inner wall of the barrel, making full use of the thrust of the gunpowder deflagration and the torque given by the rifling. Finally, the effect just demonstrated was achieved.

"Except for this gun, how many steps can the average accurate and effective killing range of other guns reach after using improved projectiles?" Liu Xinqi asked.
