Are you new to the world of shooting and trying to understand the difference between rimfire and centrefire ammunition? It can seem confusing at first, but this guide is here to help. We'll break down the pros and cons of each type, explain their common uses, and walk you through how to find and join UK shooting clubs that cater to both. By the end, you'll have a clear understanding of which option is right for your shooting journey.
Understanding Rimfire and Centrefire Ammunition
The fundamental difference between rimfire and centrefire types of ammunition lies in how they are designed to fire. It all comes down to the location of the priming compound—the substance that ignites the gunpowder when struck by the firing pin. This single design choice affects everything from the cartridge's power and cost to its reliability.
In a rimfire cartridge, the primer is located in the hollow rim at the base of the cartridge case. Conversely, centerfire ammunition contains a separate, replaceable primer component pressed into the center of the case's base. Let's explore what this means for you as a shooter.
What is Rimfire Ammunition?
Rimfire ammunition gets its name because the firing pin strikes the rim of the cartridge to ignite it. During manufacturing, a wet priming compound is placed inside the case and spun, using centrifugal force to spread it evenly into the hollow rim. Once dry, the case is filled with powder and a bullet is seated, with the most common rimfire cartridge being the .22 Long Rifle.
Because the firing pin must crush the rim to work, the rimfire cases must be made of thin, soft metal. This inherent design limits the amount of pressure the cartridge, such as the Smith & Wesson, can safely handle, which in turn limits its power. You can easily identify a fired rimfire round by the small indentation left by the firing pin on the edge of the case head.
This design is most famously used in the .22 Long Rifle (.22 LR) cartridge, making Winchester rimfire firearms incredibly popular for training, plinking, and pest control. Most firearms chambered for .22 LR, .17 HMR, and .22 WMR are types that use rimfire ammunition.
What is Centrefire Ammunition?
Centrefire ammunition uses a more modern and robust ignition system. Instead of having the primer integrated into the case, a centerfire cartridge has a dedicated pocket at the base of the cartridge. A separate component, called a primer (which looks like a small percussion cap), is inserted into this pocket.
When you pull the trigger on a centrefire firearm, the firing pin strikes this central primer, which ignites the gunpowder. Because the case doesn't need to be crushed, centerfire cartridge cases can be made much thicker and stronger. This allows them to handle significantly higher pressures, resulting in more powerful and higher-velocity rounds.
How can you tell if your gun uses rimfire or centrefire ammo? The easiest way is to look at a fired cartridge case. A centrefire case will have a distinct, circular dent in the very center of its base, where the firing pin struck the separate primer. A rimfire case will have a dent on its outer edge.
Key Differences Between Rimfire and Centrefire
When comparing rimfire vs centerfire, the main difference is the primer's location and design. A rimfire cartridge has its priming compound integrated into the rim, ignited when the firing pin strikes the edge of the case. This rimfire cartridge typically contains less powder than a centerfire cartridge, which uses a separate primer in the center of the case head, struck by a central firing pin.
This distinction leads to other key differences in power, cost, and reusability. Rimfire cases are thin and generally not reloadable, while the thick, durable construction of centerfire cases allows them to be reloaded multiple times. This is a major factor for high-volume shooters.
Different cartridge combos are available for each type, from the small .22 Long Rifle to powerful long-range centerfire cartridges, including the Hornady Magnum Rimfire.
| Feature | Rimfire | Centrefire |
|---|---|---|
| Primer Location | Integrated into the hollow rim of the case. | Separate, replaceable primer in the center of the case base. |
| Case Thickness | Thin and soft, as it must be crushed to ignite. | Thick and strong to handle high pressures. |
| Power Level | Lower pressure and power. | Capable of much higher pressures and power. |
| Reloadable? | No, the case is permanently deformed. | Yes, the spent primer can be replaced. |
| Cost | Generally much less expensive. | More expensive per round. |
Pros and Cons of Rimfire vs Centrefire Firearms
Choosing between rimfire and centrefire firearms for firearms owners involves weighing their distinct advantages and disadvantages. Rimfire ammunition is known for its affordability and low recoil, making it an excellent starting point for new shooters. It's perfect for a fun day of target practice without breaking the bank.
On the other hand, centrefire rounds offer superior power, range, and reliability, which are crucial for activities like big game hunting or serious long-range competition. However, this performance comes with a higher cost per shot and more noticeable recoil. Let's look closer at these pros and cons.
Cost and Availability
One of the most significant advantages of rimfire ammo is its cost. Due to a simpler manufacturing process and smaller components, rimfire cartridges and long cartridges are almost always the cheapest ammunition you can buy. For the price of a single premium centerfire round, you can often purchase a whole box of .22 LR.
This affordability makes rimfire ideal for high-volume shooting, varmint hunting, practice, and casual plinking. You can spend an entire afternoon at the range honing your skills without worrying about the cost. While premium match-grade rimfire ammo exists, it is still a bargain compared to its centerfire counterparts.
In contrast, centerfire ammunition is more expensive due to its complex design, larger components, and the inclusion of a separate primer. While some common calibers are mass-produced, many specialized rounds from boutique reloaders can be quite pricey.
- Rimfire Ammo: Bulk packs offer a very low cost-per-round, ideal for training.
- Centerfire Ammunition: Costs more due to thicker cases and separate primers.
- Reloading: Centerfire cases can be reloaded, which can reduce long-term costs for enthusiasts.
Performance: Power, Accuracy, and Recoil
When it comes to performance, the rimfire vs centerfire debate shows clear distinctions. Centrefire cartridges are built to handle much higher pressures, allowing them to achieve significantly higher velocities and greater power, which creates a greater chance of successful hunting. This translates to a longer effective range and more energy delivered to the target, making them the only choice for hunting large game or shooting at long distances.
Rimfire ammunition, like the popular .22 Long Rifle cartridge, has very low recoil and a much quieter report, operating at velocities below the speed of sound. This makes it comfortable to shoot for extended periods and is a fantastic tool for teaching new shooters the fundamentals without causing them to develop a flinch. The trade-off is a much shorter effective range and less power.
While both types can be highly accurate, centrefire rounds generally maintain their accuracy over longer distances due to higher bullet speed and better ballistic performance. However, match-grade rimfire rifles are capable of incredible precision within their effective range, often under 150 yards.
Reliability and Ease of Use
Reliability is a key reason why many shooters prefer centrefire guns, especially for defensive or hunting applications. The centrefire priming system is inherently more reliable. A separate, precisely manufactured primer provides a more consistent ignition compared to the spun-in compound of a rimfire cartridge case, making it essential when considering options like lead bullets.
With bulk-pack rimfire ammunition, it's not uncommon to experience a "dud" round that fails to fire. This is often due to small voids or inconsistencies in the priming compound within the rim. While premium rimfire ammo has a much lower failure rate, the possibility is always higher than with quality centerfire rounds.
This is why, for any situation where absolute reliability is critical, a centerfire firearm is the better choice. For casual target shooting with a rimfire gun, a misfire is a minor inconvenience that can be cleared safely. However, for hunting or self-defense, that level of uncertainty is unacceptable for most people.
Typical Uses for Rimfire and Centrefire Firearms
The differences in power and performance naturally lead to different applications for rimfire and centrefire firearms. Rimfire rifles are masters of the small-scale. Their low cost, minimal recoil, and quiet operation make them perfect for target shooting, training new shooters, and hunting small game or handling pest control.
In contrast, centerfire firearms are built for bigger tasks. Their power and long-range capabilities are essential for ethically hunting big game animals. They also dominate in competitive shooting disciplines that require precision at hundreds of yards. Let's explore the common uses for each.
Common Rimfire Applications
Rimfire rifles and handguns, such as the Henry Rimfire, are exceptionally versatile for a variety of activities where high power isn't a necessity. Their most popular use is for plinking—informal target shooting at cans, spinners, or paper targets. The low ammunition cost means you can shoot all day for fun.
Are rimfire guns suitable for hunting? Absolutely, for the right quarry. A rimfire gun is an excellent tool for small game hunting, such as squirrels and rabbits. They are also widely used for pest control on farms and rural properties, effectively dispatching small nuisance animals without the noise and power of a larger rifle.
More powerful rimfire cartridges like the .22 Winchester Magnum Rimfire (.22 WMR) or .17 HMR extend the effective range for hunting slightly larger animals like coyotes or groundhogs.
- Target Shooting: Ideal for beginners and practice due to low recoil and cost.
- Small Game Hunting: Perfect for ethically taking animals like squirrels and rabbits.
- Pest Control: Quiet and effective for managing small pests around a property.
Popular Centrefire Uses
Centerfire firearms excel where power and distance are required. Their primary use in the civilian world is for hunting medium to big game animals, such as deer, elk, and boar. The energy and high velocity of centerfire rounds ensure an ethical and humane harvest at responsible distances.
These firearms, including .22 caliber rimfire firearms, are also the standard for most long-range shooting disciplines. Competitions that involve engaging targets at 500, 800, or even 1,000 yards and beyond rely exclusively on the flat trajectory and consistent performance of centerfire rounds. Their ability to buck the wind and maintain accuracy over long distances is unmatched by rimfire.
Finally, the vast majority of handguns and rifles intended for self-defense and law enforcement use are centerfire firearms. This is because of their proven reliability and stopping power, which are critical factors when lives are on the line.
- Big Game Hunting: Essential for ethically hunting animals like deer and larger species.
- Long-Range Shooting: The only choice for competitive and recreational shooting at long distances.
- Self-Defense: The standard for reliability and effectiveness in defensive handguns and rifles.
Choosing Between Rimfire and Centrefire for Beginners
For new shooters, the rimfire vs centerfire decision can feel momentous, but there's a clear answer for most beginners. Rimfire is almost always the better choice to start with. Its low recoil, minimal noise, and inexpensive ammunition allow you to focus on learning the fundamentals of marksmanship—stance, grip, sight alignment, and trigger control—without intimidation.
Once you've mastered the basics, you can consider what you want to do next. Your skill level, budget, and shooting goals will determine when and if you should move up to a centrefire firearm. Let's examine the factors you should consider.
Factors to Consider (Skill Level, Budget, Intended Use)
When deciding which type of ammunition and firearm is right for you, three main factors come into play: your skill level, your budget, and your intended use. For beginners, a rimfire rifle is the ideal starting point. The lack of heavy recoil prevents the development of bad habits like flinching.
Your budget is another critical consideration. Rimfire ammo is significantly cheaper, meaning you can afford to practice much more. A larger budget might allow you to own both a rimfire for practice and a centrefire firearm for specific activities like hunting.
Ultimately, your intended use will guide your decision. If you plan on plinking and hunting small game, rimfire is perfect. If your goal is to hunt big game or shoot at long distances, you will need to invest in a centrefire firearm.
- Skill Level: Beginners benefit from rimfire's low recoil and noise.
- Budget: Rimfire offers a lower cost of entry and continued practice.
- Intended Use: Choose rimfire for small game/plinking and centrefire for big game/long range.
Safety and Maintenance Considerations
Regardless of whether you choose rimfire rifles or centerfire guns, safety is the top priority. Always follow the fundamental rules of firearm safety: treat every gun as if it's loaded, never point it at anything you aren't willing to destroy, keep your finger off the trigger until you're ready to shoot, and be sure of your target and what's beyond it.
Maintenance is straightforward for both types. Regular cleaning to remove powder residue and fouling is essential for reliable function. One key difference is in the ammunition itself. The spent cartridge case from a rimfire round cannot be reused because the rim is damaged during firing.
In contrast, the durable cases of centerfire ammunition can be reloaded. This involves removing the old primer, resizing the case, adding a new priming compound via a new primer, and reloading it with powder and a new bullet. This is a popular hobby for many centrefire enthusiasts.
- Universal Safety: Always follow the core rules of firearm safety.
- Cleaning: Both firearm types require regular cleaning for reliability.
- Reloading: Centerfire cases can be reloaded; rimfire cases cannot.
What You Need to Get Started at UK Shooting Clubs
Getting started at UK shooting clubs is an exciting process for new shooters. Most clubs welcome beginners and provide a safe, structured environment to learn. You will need to become familiar with the club's rules, the necessary equipment, and the legal regulations for firearm ownership in the United Kingdom.
Whether you're interested in shooting rimfire firearms or powerful centrefire rounds, the journey begins with finding the right club and understanding the licensing process. This guide will walk you through the essential gear and legal steps required to join.
Essential Equipment and Gear
Before your first day at the range, you'll need some essential gear. The most important items are eye and ear protection. Shooting generates loud noises and can eject hot brass cases, so protecting your senses is non-negotiable. Most clubs can lend you these items for your initial visits.
Of course, you'll need a firearm and the correct ammunition. As a probationary member, the club will likely provide a rifle for you to use under supervision. This is a great way to try different types before you commit to buying your own. You'll handle everything from simple rimfire rounds to a more powerful rifle cartridge.
Once you have your own firearm, a good quality cleaning kit is crucial for maintenance. You might also consider a rifle bag or case for safe transport and a stable shooting rest or bipod to help improve your accuracy over the firearm's effective range.
- Safety Gear: Eye and ear protection are mandatory.
- Firearm and Ammo: Clubs often provide these for beginners during a probationary period.
- Maintenance: A cleaning kit is essential for keeping your firearm in good working order.
Licensing and Regulations in the United Kingdom
Firearm ownership in the United Kingdom is governed by strict regulations. To own most rimfire and all centerfire firearms, you must obtain a Firearm Certificate (FAC) from your local police force. This process is thorough and requires you to have a "good reason" for possessing each firearm you wish to own.
Joining an approved shooting club is one of the most common "good reasons" for acquiring a rifle. Clubs play a formal role in the licensing process. You will typically need to be a full member of a club before the police will grant you an FAC for target shooting.
The process usually involves joining a club as a probationary member for a period of three to six months. During this time, you will receive safety training and prove you are a responsible and safe individual. Once you become a full member, the club will support your FAC application. These regulations ensure that firearms are owned and used responsibly.

Frequently Asked Questions
Are rimfire rounds less expensive than centrefire?
Yes, rimfire rounds are significantly less expensive than centerfire ammunition. The simpler manufacturing process and smaller material requirements of rimfire ammo make it much more affordable. This allows for more frequent practice and is a major reason why it's recommended for beginners and for casual shooting fun.
Can you reload rimfire cartridges like centrefire ones?
No, you generally cannot reload rimfire cartridges. The firing process permanently deforms the soft rim of the case, making it impossible to reuse. In contrast, durable centerfire cartridge cases are designed with a separate primer that can be replaced, allowing them to be reloaded many times.
Do rimfire and centrefire calibres differ in accuracy?
Both can be very accurate within their intended ranges, factoring in bullet weight. However, centrefire calibers generally maintain their accuracy over much longer distances due to higher bullet speed and energy. Rimfire is incredibly precise at shorter ranges (under 150 yards), but centrefire excels at long-distance shooting.
Can you suggest UK clubs with facilities for both rimfire and centrefire rifle shooting, including larger calibres?
To find a suitable club, search online using terms like "full-bore rifle club UK" or check the club finders on the websites of the UK's National Rifle Association (NRA) or National Small-bore Rifle Association (NSRA). Look for clubs that specify they have ranges approved for centrefire and larger calibers.
What are the main differences between rimfire and centrefire ammunition?
The main difference is the primer location. In rimfire cartridges, the priming compound is in the rim of the case, and the firing pin strikes the rim of the cartridge base. In centerfire rounds, a separate, replaceable primer is located in the center of the cartridge base, which is where the firing pin strikes.
