Does every bullet turn? If shot in space, reaching the end of the universe or not a dream

If a gun has no bullets, it may be nothing. Modern bullets are generally composed of warheads, propellants, primers, and shells, although the calibers are very different. If you think that bullets are nothing more than that, then I can tell you that it does not have you. As simple as imagined. Among modern bullets, in addition to special bullets, there are also many types of bullets of the same caliber that are conventionally equipped by the military. They look the same at first glance, but in fact have different uses. Only an expert can see the mystery.

Soldiers will load different bullets into the gun according to the target and purpose. In order to distinguish the types of bullets, the circle at the top of the warhead is called the identification circle. Generally, the more common colors of the identification circle are green, black and colorless. This kind of bullet, painted green, is called a tracer bullet. From the name, it can be seen that this is a kind of bullet that will emit light. When the tracer bullet is fired, the ballistic is bright, dazzling and wonderful. However, the existence of the tracer bullet is not for wonderful performances. Tracer bullets are the same lethal bullets, but they are smeared on the warhead or equipped with luminescent agents such as magnesium and barium at the bottom of the warhead. The reason why a tracer bullet is called a tracer is by no means a bullet that glows at night. The word "trace" in it means to guide and tow, so the main purpose of the tracer bullet is to guide the target and correct the trajectory.

It is often said that bullets do not bend, the truth is that every bullet does. If a bullet is launched in space, it can naturally go all the way, and maybe one day it can reach the end of the universe. But on Earth, no matter how fast a bullet is, it will eventually stop, not only from the resistance of the air, but also from the Earth's own gravity. A bullet that hits the target with precision, like a bow and arrow, travels in an arc.

In the high-speed rotation, the bullet effectively reduces the gravity and obtains a more stable trajectory. In our cognition, the bullet flies forward in the "X-axis" spiral, but in fact, the flight of the bullet is a complex process. If you slow down the tail movement of a bullet in flight, you will see that the tail of the warhead draws a circle in front of your eyes, and the entire warhead is flying forward in a spiral trajectory.

However, humans often simplify the complexity. There is one kind of bullet that can completely ignore so many details. It is the "shotgun". Like other bullets, the shotgun has a primer and propellant, but it does not have a warhead. In fact, the secret of the shotgun is in the huge shell, which is composed of several small steel balls. After firing, the steel balls move forward in a scattered state. For this reason, shotguns that use shotguns are also the only weapons in modern machinery that do not require precise aiming.

The bullet that leaves the chamber has a lot of power, so have you ever wondered where the bullet was before it entered the chamber? After the bullet leaves the factory, how is it safely transported to the army and even the battlefield? First of all, they need an ammo box, which may be more difficult for ordinary people to see than bullets.
