The bullet is divided into two parts, one is the warhead, and the other is the cartridge case. The cartridge case contains propellant and primer, and there are many types of warheads. When the primer is fired, the propellant is ignited, and the warhead is quickly pressed into the barrel.
The side walls of the warhead rub against the rifling, causing it to rotate, thus ensuring that the warhead always flies toward the target.
In order to achieve accurate shooting, the warhead has to rotate and fly out. In this way, part of the energy of the bullet is converted into rotational kinetic energy. This is why the muzzle velocity of rifled guns is slower than that of smoothbore guns.
Theoretically speaking, due to the slow muzzle velocity, the kinetic energy of the warhead is reduced, and the armor-piercing ability is greatly reduced. If the kinetic energy of rotation can be utilized, the armor-piercing ability of the bullet may be improved. By modifying the warhead, the armor-piercing ability will be improved.
The threaded warhead can increase its rate of fire and provide the best penetration.
But in reality, the penetration performance of the threaded warhead is not good. This is because the warhead becomes fragile due to the necessary threads. It does not achieve the desired penetration ability, but unexpectedly obtains a powerful explosive ability, especially the cavity.
The effect is greatly improved.
In other words, threaded warheads are more suitable for cruel killings. When you see the warhead enter a person's body and directly explode the chest, the strong visual impact of blood and flesh flying everywhere will definitely satisfy the needs of many violent maniacs.
.
Not many people can make this kind of warhead. Its threads need to be cut by hand and there is no matching lathe. Any deviation in the thread will reduce the accuracy of the warhead, thus affecting the shooting accuracy and the impact of the warhead when it encounters a hard object.
The deviation bursts.
Three warheads hit the back of the heart, which indeed caused Yan Fenghuo to temporarily lose his fighting ability. By the time he regained his composure and wanted to pursue the killer, it was already too late. There was no doubt that the killer escaped smoothly and killed the men following him.
Two squads of guards.
Yan Fenghuo didn't see the killer's face, and neither did the other guards. From the time he came in to the time he left, the killer never let anyone see his face. In fact, even if someone could see his face,
, and may not be his true appearance.
Being attacked by a killer, the Prime Minister's Office was extremely nervous. While strengthening its defense, it also investigated the loopholes for the killer to sneak in.
Regarding this point, Yan Fenghuo did not interfere, but concentrated on studying the shooting point of the body armor and the deformed warhead.
"Have you seen this kind of warhead?" Yan Fenghuo asked the guard captain while holding the warhead.
The guard captain is a veteran, about forty years old, with a typical Thai face. His eyes are sharp, and his hands are covered with calluses from years of holding guns. Especially the second joints of his right thumb and index finger are calloused.
Especially generous. It is obvious that these are the traces left by the frequent use of bows and arrows.
"Threaded warheads are rare." The guard captain just glanced at it and told the specifications of the bullet: "Belgian FN Company SS190 pistol high-speed bullet, 5.7 mm caliber, special warhead, but the original steel core bullet does not have threads
The warhead is cut by hand."
Upon hearing these words, Yan Fenghuo's eyebrows twitched slightly, he raised his head and looked at the guard captain, with doubts in his eyes.
Seemingly seeing the doubts in Yan Fenghuo's eyes, the guard captain smiled and said: "I once worked in the French Foreign Legion, and I came here after leaving there. I am familiar with various weapons. There was another person who came back at the same time as me.
Comrade, he is a real weapons expert. Although this kind of warhead is very rare, it is not completely absent. For example, illegal poachers who hunt elephants like to use this kind of warhead."
This explanation is very logical and clear. When Yan Fenghuo took over, he had studied everyone's file information. It was true that the guard captain had spent several years in the French Foreign Legion.
"Where is your comrade?" Yan Fenghuo asked.
"Dead." There was a trace of sadness in the eyes of the guard captain: "He did not die in a hail of bullets, but died in an accidental car accident."
"When did you die?" Yan Fenghuo stared at the guard captain.
"Half a month ago." The guard captain narrowed his eyes and said solemnly: "When I saw these warheads, I could confirm that his death was definitely not an accident, but an elaborate murder.
There are no more than three people in the world who can cut this kind of thread by hand, and my comrade is one of them. He used to be a precision machinist and had a paranoid fanaticism towards weapons. Even in the French Foreign Legion, even
The whole world is full of famous weapons experts."
"Who is it?" Yan Fenghuo stood up.
"Aliens," the guard captain said.
Hearing this name, Yan Fenghuo's slightly narrowed eyes widened instantly. This name is so resounding that it can be recorded as a legend in the history of military industry.
There are three top-level weapon mechanics in the world: Thug Mechanic, Heavy Equipment Law, and Alien.
Thug Mechanics is committed to the research of all weapons that can kill. They are not one person, but a team. They travel to weapons companies around the world and use their technology in exchange for money; the Law of Reloading is an individual who specializes in the research of heavy weapons.
He is a crazy scientific maniac. His ultimate ideal is to destroy the entire earth. But although his ultimate ideal is **** and extremely crazy, his technology is unparalleled. Military competitions between the United States and Russia have always been rife.
His figure helps the United States today and Russia tomorrow, always hoping that these two big countries will have a fierce fight, so that he will be closer to his ultimate goal.
The alien is dedicated to the research of light weapons, including special ammunition. His thinking is always full of categories that humans cannot understand, and the guns he transforms are full of incredible uses. If you give him a rifle, he may help you transform it.
It can be turned into a howitzer, and maybe transformed into a submachine gun. If he is very interested, it is not difficult to add a few more riflings inside.
His research in the field of special ammunition is even more eye-catching. He first proposed and manufactured the mercury bullet when he was a boy. It was later written into the novel by Fuses and became widely circulated.
Mercury is toxic, and at the same time has a greater density and mobility than lead. In theory, it can indeed achieve the killing effect of dum bombs. However, this design seems feasible, but in fact it has little application value.
Just like the threaded bullet, there is no problem with the design, but the actual application value is very narrow.
To put it simply, an alien is an alien. His whims will always create something, but in the end, the applicable value of these things is very low. Of course, this is relative, thread
The bullet is definitely the best bullet for hunting elephants.
"But he is dead." The guard captain shook his head and said: "We have lost the clue, and we cannot trace the killer. Mr. Yan, with all due respect, what you should do now is to strengthen the protection of the Prime Minister, rather than trace the killer.
Killer."
"No, we must investigate." Yan Fenghuo stared at the guards guarding nervously outside the window and said as if to himself: "I have to know how he got in!"
Yan Fenghuo seemed to have forgotten how he came in...
PS: I have to travel these days, so the updates are not very timely, and the amount is small. Tomorrow's update should be at noon, and the day after tomorrow should be in the evening. After these few days, it will be stable.
