What Is the Difference Between Rimfire & Centerfire?

Rimfire and centerfire are two types of cartridge ignition systems. Both use a primer to start the process that burns the propellant and sends the bullet down the barrel. The main difference is where the primer sits and how the firing pin strikes it.

In rimfire ammunition, the priming compound sits inside the hollow rim at the base of the case. The firing pin strikes the rim to start ignition.

In centerfire ammunition, a separate primer sits in the center of the case head. The firing pin strikes that primer instead.

Feature	Rimfire	Centerfire
Primer location	Inside the case rim	Center of the case head
Common example	.22 LR	9mm Luger
Typical cost per round	Often lower	Often higher
Typical recoil	Low in common examples	Varies widely
Reloading	Not designed for normal reloading	Many suitable cases can be reloaded
Common uses	Target practice and small-game hunting	Handgun sports, rifle shooting, and hunting

These are general patterns. The exact cartridge, firearm, and intended use matter.

How Does Rimfire Ammunition Work?

Rimfire ammunition has a thin, hollow rim at the base of its case. The maker places the priming compound inside this rim.

When the firing pin strikes the rim, it crushes the metal and sets off the priming compound. This starts the burning process that ignites the propellant.

The propellant creates gas that pushes the bullet through the barrel. The bullet is the projectile that leaves the firearm. It is only one part of the complete cartridge.

Rimfire cases are usually thin because the design must allow the firing pin to crush the rim. This limits the pressure they can safely handle compared with many centerfire designs. It also helps keep many rimfire cartridges affordable.

Common rimfire cartridges

• .22 Long Rifle (.22 LR): Often used for target practice, recreational shooting, and small-game hunting.
• .17 HMR: A rimfire cartridge used for target shooting and some varmint hunting.
• .22 WMR: Also called .22 Magnum. It offers a different performance level from .22 LR.

These cartridges are not interchangeable just because they are all rimfire. A firearm must be designed for the exact cartridge it uses.

---

How Does Centerfire Ammunition Work?

Centerfire ammunition has a separate primer fitted into the center of the case head. When the firing pin strikes the primer, it starts ignition inside the cartridge.

The burning propellant creates gas that drives the bullet down the barrel. The centerfire design uses a separate primer instead of placing the priming compound inside the case rim.

This design supports a wide range of cartridge sizes and pressure levels. Centerfire ammunition is common in handguns and rifles, from small handgun cartridges to larger rifle cartridges.

Common centerfire cartridges

• 9mm Luger: Common in compatible handguns and some carbines.
• .223 Remington: Used in compatible rifles for target shooting and certain hunting uses.
• .308 Winchester: Used for target shooting and hunting with suitable rifles.
• .45 ACP: A common centerfire handgun cartridge.

Each cartridge has its own size and performance limits. For example, .223 Remington and 5.56 NATO have similar dimensions but are not automatically interchangeable in every firearm. Always check the firearm maker’s guidance.

Rimfire vs Centerfire: 9 Key Differences

1. Primer and Ignition System

The primer location is the main technical difference.

Rimfire uses priming compound inside the case rim. Centerfire uses a separate primer in the center of the case head.

This affects the case design, how the firing pin starts ignition, and how the cartridge is made. It does not, by itself, tell you the cartridge’s accuracy or overall quality.

2. Cost & Availability

Rimfire ammunition often costs less per round. The .22 LR is a common example used for practice and recreation.

Centerfire ammunition often costs more, but prices depend on the cartridge, brand, bullet type, and local supply. Some centerfire options cost less than others.

If you shoot often, the cost per round can make a large difference over time. Still, price should never be the only factor. The ammunition must match the firearm and the job.

3. Recoil & Shooting Comfort

Recoil is the force a shooter feels when a firearm fires.

Many common rimfire cartridges produce low recoil. This can make them more comfortable for practice and for people learning basic shooting skills under proper supervision.

Centerfire recoil varies a great deal. A small handgun cartridge may have manageable recoil, while a large rifle cartridge may produce a stronger push.

Firearm weight, cartridge design, bullet weight, and other factors all affect recoil. So, not every centerfire cartridge has heavy recoil.

4. Reliability

Centerfire ammunition is often seen as more reliable in general use. But neither type is certain to fire every time.

Rimfire ignition depends on the firing pin crushing the rim where the priming compound is present. If ignition fails, the cartridge may not fire.

Centerfire ammunition uses a separate primer, but it can also fail because of poor storage, damage, defects, or firearm problems.

Good ammunition and a well-kept firearm matter with both types. If a cartridge fails to fire, follow the firearm maker’s safety instructions. Do not rush to open or handle it.

5. Accuracy & Range

Neither rimfire nor centerfire is always more accurate. Accuracy depends on the cartridge, firearm, ammunition quality, shooter skill, and conditions.

Some rimfire cartridges are very accurate at suitable distances. Centerfire cartridges also cover a wide range of accuracy levels and uses.

Range works the same way. Some centerfire cartridges can work well at longer distances, but the primer type alone does not set a cartridge’s effective range. Bullet design, speed, wind, and the target all matter.

Do not judge a cartridge by its name alone. Look at the specific cartridge and the firearm maker’s intended use.

6. Power & Performance

Rimfire cartridges are usually built for lower pressure than many centerfire cartridges. This makes them useful for light practice and certain small-game uses.

Centerfire ammunition covers a wider range of performance. Some cartridges are made for handguns, while others are designed for rifles and different hunting or target needs.

More power does not always mean a better choice. The right cartridge depends on the intended use, local laws, and the firearm’s design.

7. Reloading

Rimfire cases are not designed for normal reloading. Their priming compound is built into the rim, so the case does not use a separate primer that can be replaced in the usual way.

Many centerfire cases can be reloaded with the right equipment and components. But not every case is suitable, and a case must be checked for damage.

Reloading needs proper training and reliable instructions. It should not be treated as a simple way to reuse any fired case.

8. Common Calibers

Rimfire and centerfire each include many cartridges, but their common uses differ.

Type	Examples	Common uses
Rimfire	.22 LR	Practice, recreation, small-game hunting
Rimfire	.17 HMR	Target shooting, some varmint hunting
Rimfire	.22 WMR	Recreation and certain hunting uses
Centerfire	9mm Luger	Handgun shooting
Centerfire	.223 Remington	Rifle shooting and certain hunting uses
Centerfire	.308 Winchester	Target shooting and hunting

The word caliber often refers to a bullet’s approximate diameter, while the cartridge name identifies a specific ammunition type. Two cartridges with similar names or sizes may still have different specifications.

9. Noise

Rimfire cartridges often produce less noise than many larger centerfire cartridges, but this is not a rule for every firearm or load.

Noise depends on the cartridge, barrel, firearm, and other factors. A quieter shot can still damage hearing.

Always use suitable hearing protection at a shooting range. Never assume a firearm is safe to fire without protection because it uses rimfire ammunition.

Can You Use Rimfire & Centerfire Ammunition in the Same Firearm?

No. Rimfire and centerfire ammunition are not interchangeable. They use different ignition systems and require a firearm made for the correct cartridge.

Never use a cartridge just because it fits inside a firearm. A cartridge can fit and still be unsafe to fire. Check the markings on the firearm and the owner’s manual. If you are unsure, ask the manufacturer or a qualified gunsmith.

Follow these basic safety rules:

• Keep the muzzle pointed in a safe direction.
• Keep your finger off the trigger until you are ready to fire.
• Check the target and what lies beyond it.
• Use only the ammunition listed for your firearm.
• Wear eye and hearing protection.
• If a cartridge fails to fire, follow the manufacturer’s instructions and handle the situation with care.

These steps apply to both rimfire and centerfire firearms.
