Atomic Ammunition's 308 Winchester subsonic rifle ammunition delivers reliable performance for shooters who prioritize hearing protection and noise reduction downrange. This 275-grain round nose load is engineered to stay subsonic—traveling below the sound barrier—eliminating the supersonic crack that alerts game and strains ears even with a suppressor.

The 275-grain bullet weight in .308 Winchester is a proven combination for subsonic work, balancing velocity control with impact energy.

Frequently Asked Questions

Will subsonic 308 ammunition work in my suppressed rifle?

Yes. Subsonic ammunition is designed specifically for use with suppressors. The 275-grain round nose bullet in this load is optimized for suppressed .308 rifles, ensuring reliable cycling and feeding while keeping velocity below the sound barrier.

What is subsonic ammunition, and why should I use it?

Subsonic ammunition travels slower than the speed of sound (below approximately 1,125 feet per second), eliminating the supersonic crack that occurs when a bullet breaks the sound barrier. This significantly reduces noise signature, making it ideal for hearing protection, hunting in populated areas, and tactical training where noise discipline matters.

How many rounds come in each box?

Each box contains 20 rounds of Atomic Ammunition 308 Winchester subsonic ammunition.

Is this ammunition suitable for hunting?

This subsonic load is designed for suppressed rifle use and can be suitable for hunting applications where hearing protection and noise reduction are important factors. Always verify local hunting regulations and ensure the load meets ballistic requirements for your intended game and shooting distance.
