Some basic knowledge about guns

The gun is the most basic weapon for individual soldiers, and the rifling is also called rifling. Several spirals are carved in the barrel, and the warhead rotates in the barrel according to the trajectory of rifling under the impetus of gunpowder gas when launching, so that it can maintain good stability after flying out of the muzzle. So as to ensure accuracy and flight distance. The invention of the double-track changed the history of firearms. Make it more powerful and accurate. A gun that doesn't come to the double track is called a musket, and the shotgun now is a kind of musket!

Then, let's briefly talk about the firing principle of the gun. When firing, pull the trigger and release the striker in the gun. The striker hits the primer of the bullet and causes the gunpowder in the bullet to burn. Because the bullet shell is a closed environment, the instantaneous gunpowder gas has great energy. The energy released by gunpowder combustion pushes the warhead out of the barrel and shoots it out! Then, under the influence of the back thrust of gunpowder, the bolt slides backwards, and at the same time, the fired bullet shell is pulled out of the gun bore and thrown out of the shell throwing window, thus completing the firing of a bullet. In case of continuous shooting, the above steps will be repeated repeatedly. Until all the bullets in the magazine are gone!

Internal structure of bullets: Generally, bullets are divided into primer, shell, inner charge (gunpowder) and warhead.
