Finding the right ammunition for a suppressed .22 LR firearm can significantly impact your shooting experience. The quiet operation of a suppressor depends heavily on the ammo's characteristics, particularly its velocity and bullet design. This guide explores the best .22 LR ammo options for suppressed use, focusing on factors like subsonic performance, accuracy, and reliability.
Understanding the Importance of Subsonic Ammo
When it comes to suppressed shooting, subsonic ammunition is king. Subsonic rounds travel slower than the speed of sound (approximately 1125 feet per second or fps), minimizing the characteristic "crack" of a supersonic bullet breaking the sound barrier. This results in a much quieter shooting experience, maximizing the suppressor's effectiveness. Supersonic ammo fired through a suppressor can still produce a noticeable sound.
Key Factors to Consider When Choosing .22 LR Ammo for Suppressors
Several factors influence the performance of .22 LR ammo in suppressed firearms:
1. Velocity:
As mentioned, subsonic velocity is crucial. Look for ammunition with a listed velocity under 1100 fps. Slightly higher velocities might still be manageable, but the quieter the better.
2. Bullet Weight:
Heavier bullets tend to be more stable and accurate at subsonic velocities. Look for bullets weighing between 40 and 45 grains. These heavier projectiles generally provide better accuracy and reduce the chance of keyholing (the bullet tumbling and creating an oblong hole in the target).
3. Bullet Design:
Round nose or hollow point bullets generally function best in suppressed firearms. These designs tend to be more stable at lower velocities and create less leading in the barrel. Avoid bullets with pointed tips as they are more prone to issues with suppressed use.
4. Reliability:
Consistent ignition and reliable feeding are essential. Choose brands with a solid reputation for reliability in various firearms. Testing different brands is often necessary to find what works best in your specific gun.
5. Ammunition Type:
While many subsonic .22 LR rounds are lead-round nose or lead-hollow point, consider the environmental impact and your shooting location's regulations. There are also copper-plated and fully jacketed subsonic options available.
Top .22 LR Ammo Choices for Suppressed Applications:
This is not an exhaustive list, and the best ammo will always depend on your specific firearm and preferences. Always test various ammunition types to determine what works best for your setup. However, these brands and types are frequently recommended:
- CCI Quiet-22: This specifically designed ammunition is known for its low velocity and exceptionally quiet operation. It's a popular choice for suppressed shooting, but availability can sometimes be an issue.
- Aguila Super Colibri: This ammunition offers incredibly low velocity and is exceptionally quiet, but it is also very low-powered and may not cycle reliably in all firearms.
- SK Standard Plus: This ammunition provides a good balance of accuracy and subsonic performance at a more readily available price point.
- Federal AutoMatch: While not explicitly marketed for suppressed use, this ammunition often performs well due to its consistent velocity and reliable feeding. Check velocity specifications to ensure it's subsonic.
Testing and Experimentation:
The best way to find the perfect .22 LR ammo for your suppressed firearm is through experimentation. Start by trying a few different brands and types from the suggestions above and carefully note the results, focusing on accuracy, reliability, and sound suppression. Remember to always follow safe firearm handling practices.
