Rimfire firearms in sport shooting – a guide for beginners and advanced shooters

Sport shooting is a discipline that requires precision, concentration, and the right equipment. One of the most commonly used types of firearms in this field is the rimfire firearm, particularly popular due to its low recoil, relatively quiet operation, and affordable ammunition. Although structurally less “powerful” than centerfire firearms, it forms the foundation of many pistol and rifle competitions.

From this article you will learn:

• what rimfire firearms are and where they are used?
• how a rimfire cartridge is constructed and how it works?
• how to choose the right equipment for your needs?
• what the main advantages and limitations of this type of firearm are?

Rimfire firearms in sport shooting

In sport shooting, competitions using rimfire ammunition—particularly .22 LR—are among the most common. Its defining feature is that ignition occurs when the firing pin strikes the rim of the cartridge case rather than its center. This makes the firearm typically lighter, mechanically simpler, and capable of producing significantly less recoil.

For athletes, this translates into greater shooting comfort, quicker mastery of technical fundamentals, and the ability to fire long strings of precise shots without excessive fatigue. The relatively low noise level means that ear protection is sometimes not strictly necessary, although the use of headphones or earplugs is still recommended.

It is worth emphasizing that despite its relatively low energy, rimfire firearms still require a license and responsible handling. They should also not be confused with airguns, which operate on an entirely different principle.

Construction of a rimfire cartridge

A rimfire cartridge is an integrated unit—its components form a single, ready-to-use whole. It consists of:

• a thin-walled case that also serves as the carrier for the priming compound,
• an initiating compound distributed around the rim of the case head,
• a propellant charge,
• a projectile.

The case binds all components together and enables proper ignition of the propellant. Depending on the manufacturer, the characteristics of the ammunition may vary—this affects accuracy, muzzle velocity, and price. American-made rimfire ammunition is particularly popular, although many reputable manufacturers from around the world offer high-quality products.

How does rimfire ammunition work?

The operating principle is exceptionally simple. When the trigger is pulled, the firing pin strikes the rim of the cartridge case. At that point lies a layer of priming compound, which ignites upon impact. The flame then travels to the propellant charge, triggering a rapid chemical reaction. This reaction creates high gas pressure that pushes the bullet out of the case and propels it down the barrel.

This straightforward design makes rimfire cartridges inexpensive, lightweight, and highly consistent—ideal for sport shooting.

How to choose a rimfire firearm?

Choosing the right firearm depends on individual preferences and intended use. In stores, you can find both rimfire pistols and rifles, as well as a wide range of accessories and ammunition. The most important thing is to match the firearm to your ergonomics, skill level, and type of training.

It is important to remember that, under Polish law, firearms cannot be purchased online. Obtaining the appropriate license is also required.

Use in sport and popularity

Rimfire firearms are eagerly chosen by both beginner and advanced athletes. Their low recoil, quiet operation, and high precision make them ideal tools for learning the fundamentals as well as for competing in tournaments. In many disciplines, they stand as a full-fledged counterpart to centerfire firearms.

Athletes appreciate them for their safety, predictability, and user comfort. Additionally, .22 LR ammunition is widely available and relatively inexpensive, allowing for frequent training without significant cost.

Rimfire firearms – advantages and limitations

Both short and long firearms chambered for rimfire cartridges are gaining popularity due to their versatility. They combine ease of handling with the ability to conduct precise training. Their key advantages include low recoil, reduced noise, and high shot-to-shot consistency. Although the bullet’s energy is lower than that of centerfire ammunition, rimfire firearms perform excellently for both sport and training purposes.

Rimfire firearms form the foundation of modern sport shooting. Their design, user comfort, and the availability of ammunition make them an excellent choice for beginners and experienced competitors alike. This type of equipment blends tradition, functionality, and modern solutions while ensuring safety and high precision.
