Quick Answer
A suppressor can be used with subsonic ammunition, but it's primarily designed to reduce the noise of supersonic rounds. Subsonic ammunition is already quieter than its supersonic counterparts, so the suppressor's noise-reducing effect may be less noticeable. However, it can still be beneficial in certain situations.
Choosing the Right Subsonic Ammunition
When selecting subsonic ammunition for use with a suppressor, look for rounds with a muzzle velocity of 1,000 feet per second or lower. This ensures that the bullets are traveling at or below the speed of sound, minimizing the sonic boom and making the suppressor’s noise-reducing effect more noticeable. Examples of suitable subsonic cartridges include the .223 Remington with a 40-grain bullet and the .300 AAC Blackout with a 220-grain bullet.
Mounting and Maintaining the Suppressor
Properly mounting a suppressor on your firearm is crucial for optimal performance. Use a high-quality, suppressor-specific mount to ensure a snug fit and to prevent any damage to the suppressor or the barrel. Regularly clean and maintain your suppressor to prevent the buildup of carbon and debris, which can affect its performance and accuracy. Typically, cleaning the suppressor after every 100 rounds is recommended.
Hunting with a Suppressor
When hunting with a suppressor, consider the distance to your target and the type of game you’re pursuing. At close ranges, the suppressor’s noise-reducing effect may be more beneficial, as it reduces the noise that can spook game. However, at longer ranges, the suppressor’s effect may be less noticeable. Always follow local regulations and guidelines for hunting with a suppressor, as rules and restrictions vary by region.
