Corrected entry: Never heard of bullet-speeds being expressed in mph, usually in meters per second or feet per second. Anyhow, 360 mph is still well above the sound barrier, so any suppressor or silencer will NOT silence the sharp whip-like crack of a bullet going through the sound barrier.

Correction: 360 mph is about half the speed of sound.
