Finding the right ammunition for your rimfire rifle can feel overwhelming. With so many options available, understanding the nuances of different types of .22 rimfire ammo is crucial for accuracy, performance, and safety. This in-depth guide explores the world of .22 rimfire rifle ammo, covering everything from common calibers to specialized rounds. We'll delve into the specifics to help you make informed choices for your shooting needs.
Understanding .22 Rimfire Cartridges
The term ".22 rimfire" refers to a family of cartridges where the primer is located in the rim of the cartridge case, rather than in a separate cup at the base (like centerfire cartridges). This design is generally associated with lower power and cost-effectiveness, making it popular for target shooting, small game hunting, and plinking.
Common .22 Rimfire Calibers:
While .22 LR is the most common, several other calibers exist:
- .22 Long Rifle (.22 LR): The workhorse of rimfire ammunition. Available in countless variations, from inexpensive plinking rounds to high-velocity rounds for hunting.
- .22 Short: An older, shorter cartridge with less power than .22 LR. Mainly used for older firearms.
- .22 Long: A slightly longer and more powerful cartridge than .22 Short, but less powerful than .22 LR. Less common today.
- .22 Winchester Magnum Rimfire (.22 WMR or .22 Mag): A significantly more powerful cartridge than .22 LR, suitable for small game hunting and pest control.
- .22 Hornet: Technically not a rimfire, but often grouped with them due to its similar size and historical usage. It's a centerfire cartridge, offering substantially more power.
Factors to Consider When Choosing .22 Rimfire Ammo:
Choosing the right ammo depends on several factors:
- Intended Use: Target shooting, plinking, small game hunting, or pest control each require different ammunition characteristics.
- Firearm Type: Some rifles are better suited to certain types of ammunition. Check your firearm's manual for recommended cartridges and velocity ranges.
- Accuracy and Velocity: Different rounds offer different levels of accuracy and velocity. High-velocity rounds are better for hunting, while target rounds prioritize accuracy.
- Cost: .22 LR ammo is generally inexpensive, while .22 WMR is more costly.
- Availability: Certain types of ammunition can be harder to find, especially during periods of high demand.
Types of .22 Long Rifle Ammunition:
The .22 LR cartridge boasts a wide variety of options, each designed for a specific purpose:
- Standard Velocity: Offers a balance between accuracy and cost-effectiveness. Ideal for plinking and casual target shooting.
- High Velocity: Provides higher muzzle velocity for increased range and energy. Suitable for small game hunting.
- Subsonic: Designed to travel below the speed of sound, minimizing noise. Great for hunting where noise is a concern and for suppressed firearms.
- Hollow Point: Features a hollow point in the bullet, increasing expansion upon impact. Primarily used for hunting and pest control.
- Solid Point: A simple round-nosed bullet ideal for target shooting and plinking.
- CCI Mini-Mag: A well-regarded high-velocity round known for its accuracy and reliability. Often preferred for small game hunting.
- Federal AutoMatch: Designed for semi-automatic pistols and rifles, known for reliable feeding and function.
- Remington Golden Bullet: A popular choice for its balance of accuracy, reliability, and affordability.
.22 WMR (Magnum) Ammunition:
The .22 WMR offers considerably more power than .22 LR, making it a suitable choice for small game hunting and pest control. It's particularly effective against squirrels, rabbits, and similar sized animals. The higher velocity results in a flatter trajectory, improving accuracy at longer ranges. However, this increased power comes at a cost—both in terms of price and recoil.
Choosing the Right Ammo for Your Needs:

| .22 LR Subsonic | <1100 | Suppressed Shooting | Medium | Medium |
| .22 WMR | 1400-1700 | Small Game Hunting | High | Medium |
Note: Velocities can vary depending on the manufacturer and specific load.
Safety First: Handling .22 Rimfire Ammunition
Always prioritize safety when handling any ammunition. Here are some crucial points to remember:
- Never point a firearm at anything you are not willing to destroy.
- Always treat every firearm as if it were loaded.
