The basic components of ammunition are the case, gunpowder, primer, Bullet or Projectile, while Wad is a further component found in shotshells.

What Is An Ammunition Cartridge?
Ammunition can be anything if we are picky with our definitions, as many gun owners are. You are technically using ammunition when you throw a rock or insult someone. However, in the world of firearms, we load our weapons with ammunition.
Some people mistakenly refer to ammunition as “bullets.” To the serious gun person, that phrase actually sounds like fingernails on a chalkboard and is improper. The proper term for firearms ammunition is “cartridge,” although “round” or “load” are also acceptable terms.
Gun ammunition that has already been put together is simply a cartridge. The “bullet” is only part of the package. (We’ll discuss that shortly.) Or, to put it another way, you load cartridges into your hunting rifle or handgun rather than bullets.
Don’t walk in and ask for 9mm bullets unless you want to make the normally cheerful gun store employee a grumpy curmudgeon. Say instead that you’re looking to buy 9mm ammunition or cartridges.
Basic Parts Of Ammunition
Case Or Casing
Unlike shotgun ammunition, which is typically cased in plastic, an ammunition casing is not always made of metal.
The part of the cartridge that is lifted or taken out of the firing chamber by the gun’s extractor is the case. Brass is what you see flying around shooters during intense combat in action movies.
Consider the case as a container that keeps all the parts together. Usually, in the case’s head, the primer rests in a tiny pocket. The case is filled with propellant, and the bullet is placed at the case’s open end.
Sometimes called “brass,” the case can actually be brass, steel, or aluminum for handguns and rifles. Shotgun shells are also a “case” and are typically made of plastic.
Primer
Primers are hit by the firing pin of a gun. The primer is an explosive chemical compound contained in a metal cup. The priming compound is crushed against the anvil when the firing pin strikes the primer cap. This causes a tiny explosion in the case, which ignites the propellant.
A rimfire cartridge’s case’s rim is where the primer is located. The primer of a centerfire cartridge is located in the middle of the case’s base. Berdan and Boxer primers are the two commonly used kinds of primers in centerfire cartridges.
Propellant Or Powder
Sometimes called gunpowder (although serious gun nerds typically prefer the term “propellant”), the propellant is usually a mixture of saltpeter, sulfur, and charcoal. Gas inside the cartridge rapidly expands as a result of this compound’s rapid combustion, which is faster than rocket fuel. Since the gas has nowhere else to go, it takes the easiest route and releases the bullet from the case. It then accelerates as it descends the barrel and moves closer to the object you want to hit.
Bullet Or Projectile
Although it’s not technically correct, you may occasionally hear people refer to an entire ammo cartridge as a bullet. The actual projectile that emerges from the end of your barrel and travels in the direction of your target is called a bullet. Numerous materials are used by manufacturers to create bullets. For some, lead is the only material used. On others, the lead might be protected by a copper jacket.
Additionally, we use various bullet styles for a variety of purposes. For instance, some bullet types include jacketed hollow points, total metal jackets, lead round noses, soft points, and full metal jackets. What you want to achieve will determine which you use.
Slugs and shots are the names we give to the shotgun projectiles that we use with shotshells. A slug is one solid piece that is typically made of lead. The shot is a collection of pellets made of lead, steel, bismuth, or tungsten alloy. The sizes and quantities of shot pellets can vary.
5. Wad
In a shotshell, there is a paper or plastic seal and/or shot container separating the powder from the slug or shot. The wad holds the shot together and stops gas from escaping through it as it travels through the barrel.
Summary
Bullets come in a variety of materials in addition to different designs. Some are completely made of lead. Others might be copper-coated lead. Others might be made entirely of copper.
