What Are Rimfire and Centerfire Ammunition?

Rimfire and centerfire are the two primary types of cartridges. Each has unique characteristics that affect performance, cost, and uses.

Rimfire Ammunition

Rimfire ammunition gets its name from the location of the primer contained within the rim of the cartridge base. The firing pin strikes the rim and ignites the primer, which ignites the gunpowder and propels the bullet forward. Rimfire cartridges have thinner casings and are designed for smaller calibers, such as the popular .22LR. They are lightweight, inexpensive, and ideal for beginners. They’re also perfect for target shooting. However, their thinner casings make them less powerful and not reloadable.

Centerfire Ammunition

Centerfire ammunition is named for the primer’s position at the center of the cartridge base. This primer is a separate component that can be replaced when reloading spent cartridges. Centerfire rounds, like those used in handguns or large hunting rifles, are used in various calibers. Rifle ammo is known for its durability, power, and versatility.

Key Differences: Rimfire vs Centerfire

Cost:

• Rimfire Ammunition: Generally more affordable due to its simpler construction and smaller size. It makes an excellent choice for target practice, plinking, or introducing new shooters to firearms.
• Centerfire Ammunition: It is more expensive because of its heavier construction and the ability to reload spent casings. This adds value for frequent shooters or hunters. 

Performance: 

• Rimfire Ammunition: It’s less powerful but offers adequate performance for small game and close-range target shooting.
• Centerfire Ammunition: It outshines rimfire regarding reliability, range, and power. Its thicker casing handles higher pressures. It is most suitable for precision shooting, hunting and defensive applications. 

Uses:

• Rimfire Ammunition: It’s ideal for small-game hunting, casual target practice, and teaching shooters because of its low recoil and cost.‍
• Centerfire Ammunition: It’s suited for large game hunting, tactical applications, and self-defense. This is where greater stopping power and reliability are crucial.

Firearms like the Glock 19, AR-15, and hunting rifles are all designed for centerfire cartridges. As a result, they are versatile for various purposes. 

Pros and Cons of Rimfire and Centerfire Ammo
