Subsonic .223: Quiet, Controlled, and Purpose-Built
Posted Aug 20, 2025
The .223 Remington is one of America’s favorite calibers—fast, flat-shooting, and versatile. But what happens when you slow it down? At Detroit Ammunition Company, we’ve developed a subsonic .223 load designed for shooters who value sound reduction, accuracy, and control above raw velocity.
Why Subsonic?
Supersonic .223 ammo breaks the sound barrier, producing the familiar crack that makes suppression difficult. By keeping velocities under 1,125 feet per second, our subsonic loads eliminate that crack for a significantly quieter report.
What to Expect
Because of the reduced powder charge needed to maintain subsonic speed, these rounds will not cycle semi-automatic rifles. Instead, they are best suited for:
- Bolt-Action Rifles – Ideal for ultra-quiet suppressed shooting.
- Single-Shot Platforms – Maximum control with minimal noise.
- AR-15s Used as Straight-Pulls – Manually cycling the action allows you to enjoy subsonic performance in your AR.
Key Benefits
- Whisper-Quiet with a Suppressor – Perfect for range work, pest control, or discreet shooting.
- Reduced Recoil – Comfortable, stable, and easy to shoot for long sessions.
- Precision-Oriented – Subsonic velocity stabilizes the projectile for short- to mid-range accuracy.
Who It’s For
Our Subsonic .223 is designed for shooters who want the quietest possible experience and understand the trade-off in semi-auto functionality. If you’re running a suppressed bolt gun, testing precision subsonic setups, or just curious about the performance difference, this load offers a unique shooting experience.
