How Does a Rimfire Rifle Work?
When you fire a rimfire rifle, the firing pin strikes the cartridge’s rim, crushing the priming compound inside. This impact ignites the primer, sparking the propellant to burn rapidly.
The burning propellant creates gases that build pressure, pushing the bullet down the barrel with consistent accuracy and low recoil.
Rimfire rifles are simple, reliable, and ideal for small game or target shooting.
They’re a favorite among many shooters because they’re easy to use and maintain. Keep exploring to understand why rimfire rifles are such a popular choice among shooting enthusiasts.
Key Takeaways
- A rimfire rifle fires by striking the cartridge rim, which ignites the priming compound inside the rim. This spark then sets off the propellant.
- The propellant produces expanding gases that push the bullet forward. The cartridge case holds both the priming compound and propellant, containing the gases and maintaining pressure during firing.
- Rimfire rifles use a simple and cost-effective ignition system. This makes them ideal for small game hunting and target shooting.
- These rifles also offer low recoil and reliable ignition. Plus, they deliver accurate performance at short to medium ranges.
How Rimfire Rifle Cartridges Ignite and Propel Bullets
When you pull the trigger on a rimfire rifle, the firing pin strikes the rim of the cartridge, crushing the impact-sensitive priming compound embedded there. This primer, located in the rim, initiates impact ignition as the firing pin’s strike creates a spark.
That spark ignites the propellant inside the cartridge case. As the propellant burns, it produces rapidly expanding gases, generating high pressure within the case.
The burning propellant creates expanding gases that build high pressure, propelling the bullet forward.
This pressure forces the bullet out of the cartridge and propels it down the barrel. The cartridge case holds everything together during ignition, ensuring the bullet moves forward efficiently.
This entire sequence—from firing pin to ignition—relies on precise interaction with the priming compound in the rim. That’s what makes rimfire cartridges unique in how they ignite and propel bullets.
Why Rimfire Rifles Are Ideal for Small Game and Target Shooting
Because rimfire rifles use cartridges with priming compounds embedded in the rim, they offer a simpler and more cost-effective option for shooters. You’ll appreciate their low recoil and accuracy, making them perfect for small game hunting and target shooting at short to medium ranges.
Rimfire rifles’ affordability encourages frequent practice without breaking the bank. Their light weight and quiet shot help you stay focused and comfortable.

| Accuracy | Precise shots | Satisfaction |
With rimfire rifles, you get a dependable, enjoyable shooting experience tailored for small game and target shooting.
Frequently Asked Questions
Why Is 22 Called Rimfire?
You call it “22” because the bullet diameter measures about 0.222 inches. It’s rimfire since the primer sits in the cartridge’s rim, unlike centerfire rounds where the primer’s at the center of the case base.
Why Is Rimfire Less Powerful?
You’ll find rimfire less powerful because its delicate brass case acts like a fragile shield, limiting pressure and propellant. This means your shots carry less force, keeping power modest but precision steady and reliable in your hands.
Are Rimfire Cartridges Still Available?
Yes, you’ll find rimfire cartridges like .22 LR widely available at most sporting goods stores. Manufacturers still produce popular types, so whether you’re hunting, training, or shooting recreationally, you won’t struggle to get ammo.
Which Rimfire Caliber Is the Most Powerful?
If power were a race, the .17 HMR would sprint ahead, boasting the highest velocity and energy among rimfire calibers. You’ll find it outmatches the .22 WMR, making it your go-to for maximum rimfire punch.
