The whisper-quiet allure of suppressed firearms is undeniable, and the .22 LR caliber is a favorite for its affordability and manageable recoil. However, not all .22 LR ammo is created equal, especially when it comes to suppressed shooting. Choosing the right ammunition significantly impacts the performance and longevity of your suppressor. This guide explores the best .22 LR ammo specifically designed or well-suited for suppressed use.
Understanding the Needs of Suppressed .22 LR Shooting
Suppressors work by slowing down and expanding the gases produced by a gunshot, reducing the sound. With .22 LR, the relatively low pressure and the projectile's light weight present unique challenges. Improper ammunition can lead to:
- Increased Noise: Subsonic ammunition is crucial. Supersonic rounds create a noticeable "crack" even with a suppressor.
- Poor Suppressor Performance: Dirty ammo leaves residue that reduces suppressor efficiency and necessitates more frequent cleaning.
- Unreliable Cycling: Some ammo's low power might lead to malfunctions in certain firearms, especially semi-automatic pistols.
- Lead Buildup: Lead fouling is a significant concern with .22 LR suppressors, impacting performance and requiring more frequent cleaning.
Top .22 LR Ammo Choices for Suppressors
Several factors contribute to what makes .22 LR ammo optimal for suppressed shooting:
- Subsonic Velocity: This is paramount for reducing noise. A velocity below 1100 feet per second (fps) is generally considered subsonic.
- Clean-Burning Powder: Reduces fouling and extends the time between cleanings.
- Consistent Performance: Reliable cycling in your firearm and consistent accuracy are crucial.
- Ammunition Type: Hollow points, solid points, and even CCI Quiet-22 are all viable options, each with its advantages.
Let's delve into some of the top contenders:
1. CCI Quiet-22
- Key Feature: Designed specifically for quiet operation. Uses a low-velocity, subsonic round.
- Pros: Extremely quiet, reliable cycling in most firearms.
- Cons: Lower accuracy than some other options, relatively high price.
2. SK Standard Plus Subsonic
- Key Feature: Known for its consistent accuracy and subsonic velocity.
- Pros: Good accuracy, reliable cycling, relatively clean-burning.
- Cons: Can be more expensive than other options.
3. Aguila Super Extra Subsonic
- Key Feature: Subsonic velocity and good accuracy for the price.
- Pros: Affordable, decent accuracy, relatively clean-burning.
- Cons: Not as consistently accurate as SK Standard Plus.
4. Remington Thunderbolt Subsonic
- Key Feature: Affordable subsonic option.
- Pros: Low cost.
- Cons: Can be less accurate and more prone to fouling than higher-end options.
Table 1: Comparison of Top .22 LR Ammo for Suppressors
| Ammunition | Velocity (fps) | Accuracy | Cleanliness | Cost |
|---|---|---|---|---|
| CCI Quiet-22 | ~710 | Fair | Good | High |
| SK Standard Plus Subsonic | ~1050 | Excellent | Excellent | High |
| Aguila Super Extra Subsonic | ~1030 | Good | Good | Medium |
| Remington Thunderbolt Subsonic | ~1050 | Fair | Fair | Low |
Note: Velocities can vary slightly depending on barrel length and other factors. Accuracy is a subjective assessment based on general user feedback.
Beyond the Ammo: Factors Affecting Suppressed .22 LR Performance
Even with the best ammo, other factors influence your suppressed shooting experience:
- Suppressor Design: A well-designed suppressor is essential for optimal performance.
- Firearm Compatibility: Some firearms cycle better with certain ammo types.
- Regular Cleaning: Keep your suppressor clean to maintain its effectiveness.
- Environmental Conditions: Temperature and humidity can affect performance.
Case Study: Comparing CCI Quiet-22 and SK Standard Plus
In a recent informal test comparing CCI Quiet-22 and SK Standard Plus Subsonic in a suppressed Ruger 10/22, the SK Standard Plus showed noticeably better accuracy at 50 yards, while the CCI Quiet-22 provided superior noise reduction, although this was less significant with an adequately designed suppressor.
Conclusion: Choosing the Best .22 LR Ammo for Your Suppressor
The "best" .22 LR ammo for your suppressor depends on your priorities. If ultimate silence is your goal, CCI Quiet-22 is a strong contender. If accuracy and reliability are paramount, SK Standard Plus Subsonic excels. For a balance of performance and affordability, Aguila Super Extra Subsonic is a solid choice. Remember to prioritize subsonic velocities and clean-burning powders for optimal suppressed shooting and the longevity of your equipment. Always test different types to determine what works best with your specific firearm and suppressor combination.
