🔍 Subsonic vs Supersonic Ammo: What’s the Difference?
The difference between subsonic and supersonic ammunition goes beyond just speed—it affects trajectory, recoil, noise, and overall performance. Here’s a clear side-by-side comparison:
| Characteristic | Subsonic Ammo | Supersonic Ammo |
|---|---|---|
| Velocity | Below ~1,125 fps (stays under the speed of sound) | Above ~1,125 fps (breaks the sound barrier) |
| Trajectory | More curved due to lower velocity | Flatter trajectory, better for longer distances |
| Kinetic Energy | Lower energy, typically less recoil | Higher energy for greater impact and range |
| Noise Level | Quieter, especially when suppressed (no sonic crack) | Louder due to sonic boom plus muzzle blast |
