How To Understand Ammo From Bullet Sizes To Bullet Types

Do you want to learn how to understand ammo right? What does caliber mean? Do you know what the anatomy of a bullet is? What is the difference between magazine and clip? I will answer all these questions and more today.

How is a bullet caliber measured

How is a bullet caliber measured? To begin to understand ammo we must answer this one first. In guns, particularly firearms, caliber or caliber is the approximate internal diameter of the barrel or the diameter of the projectile it fires, in hundredths or sometimes thousandths of an inch. For example, a 45 caliber firearm has a barrel diameter of .45 of an inch.

Rimfire and Centerfire

It is called rimfire because the firing pin of a gun strikes and crushes the base’s rim to ignite the primer. Which is inside the bottom of the cartridge. Rimfire ammo is limited to smaller calibers since the cartridge walls need to be thin enough to be able to be crushed by the firing pin and ignite the primer.

You can not reload Rimfire ammo. They do not have removable primers instead have a priming paste inside the bottom. Rimfire is generally cheaper when you can find it. Especially if assholes are not trying to make a fortune selling it.

In centerfire cartridges, the firing pin is in the center of the cartridge and can be removed after firing to put in a new one. Also, you can reload centerfire cartridges. Centerfire tends to be larger and more expensive.

Magazines and Clips

A clip is a device that is used to store multiple rounds of ammunition together as a unit, ready for insertion into the magazine or cylinder of a firearm. This speeds up the process of loading and reloading the firearm as several rounds can be loaded at once, rather than one round being loaded at a time.

A magazine is what is used to feed the weapon itself, whereas a clip is used to feed the magazine. Clips make loading of magazines much easier and faster, and in some cases, a clip is required in order for the magazine to work (e.g. M1 Garand).

Storing Magazines

I have gone in depth on how to store magazines in the past. Therefore I won’t cover it in depth. My method is to load half that you own. Under load by 2. And rotate every six months. So you can read the article or wait for the infographic on Monday.
