Bullet Sizes report

The bullet is one of the simplest weapons for killing enemies or destroying supplies in war. The bullet is a product that integrates physics, chemistry, materials science, aerodynamics, and military technology. It is not only a product of civilization but also a weapon to destroy human civilization.

Nowadays, many countries allow gun freedom where people can buy guns and bullets in statutory gun shops. More and more people are interested in military weapons. The first thing they want to know is the bullet sizes and types. Regardless of the style and shape of a bullet, it is composed of four parts: a projectile, a case, a propellant, and a flash hider.

Different guns need to be equipped with varying types of bullets and sizes. Do you also think that the larger the caliber of the bullet, the more lethality it is? That is not the case. You will find more details about bullet size and types in the following article.

Bullet Size Guide

Bullets are always produced with the improvement and evolution of firearms. Bullets were born to increase the lethality of guns further, so the caliber of the bullet is determined based on experiments, and the size of the bullet designed for different guns is different.

There are many types of guns in the world. If they are distinguished by gun caliber, they can be divided into the small caliber, medium caliber, and large caliber. Generally, those below 6 mm are called small calibers, 6-11 mm are called medium calibers, and 11 mm-20 mm are called large calibers.

Different types of guns have different functions, and the calibers of the bullets used are different. The wrong bullet size will significantly reduce the effectiveness of the guns. According to different military standards, the standard ammunition calibers of various military organizations are different.

Bullet Size or Caliber

When it comes to guns, the caliber means the diameter of the barrel. It means the diameter of the bullet that will go through it. Usually in inches or mm. Calibers are just bullet sizes, but this is not what they are called in the true sense because the bullet is a metal projectile. The round you fire is the cartridge, including the casing, powder, and primer. For a casual shooter, it is not easy to understand, and one may end up buying the wrong bullet size.
