Nah, you’d hear a crack from the bullets sonic boom, then immediately you’d hear the whistling in reverse and pitched down, followed by the pop from the gun.
The Doppler effect explains why pitch is higher for, say, an ambulance heading towards you, but as you approach the speed of sound, the sound waves all bunch up together and you’d just hear a sharp blast.
Faster than that and the sound waves created have to catch up. At 2x SoS, it would be the same pitch in reverse. Faster than that and the pitch drops.
