You'd hear the sharp sonic crack of the bullet sailing over your head at 2200+ FPS followed by the boom of the rifle.

The close flyers I experienced in Iraq were not a zing or a crack...really hard to describe the sound other than something really small cutting through the air at a high speed. Like a 1/100th scale jet slicing through the atmosphere. Very distinct sound which does not have a close equivalent.

Bullet has slowed to subsonic (below 1100 ft sec depending on altitude / elevation). So no 'mini sonic boom' / 'Whip Crack' Pop from Supersonic shockwave. FWIW, accuracy usually goes to crap, but still 'Good Enuf' to keep heads down.
In another life, could always tell when shooter was firing AK 47 based weapon or original '60s / '70s 'Nam era M16 223 ammo, as both rounds slowed down below sonic 'Whip Crack'/'Pop' speed at around 500-600 yds/mtrs (dependent on temp and air density). Where most all 'bolt action' Deer caliber' bullets stay Supersonic well past 1000 yds/mtrs.

Uhhh sure. In a gun fight there tends to be a lot more going on than just the bullets' velocities which tends to have an impact on how you perceive incoming rounds. But good on you, I guess.

Depends on wind direction. Wind has a huge effect on sound waves, not so much on supersonic bits of led. Under certain circumstances you could be in range of a bullet but never hear the sound. If you are hearing the sound I would assume you could be hit by a rifle projectile. A projectile from a deer hunting rifle could travel 7 miles.
Generally there are two sounds a hunting rifle makes. 1. The exploding powder and 2. The "crack" of the bullet breaking the sound barrier. The two sounds are markedly different but almost simultaneous.
A shotgun with subsonic projectiles goes "Boom". A rifle with supersonic projectiles goes "Pa-Tow". It's the rifle bullet you have to worry about.

Ever see what a 12 Gauge can do to a person? And at 1300FPS it is not Subsonic. As a young reporter way back in the Day I reported on a Gentlemen that was apparently cheating at a card Card Game. He took both Barrels of 12 Gauge Bird Shot at under 12 Yards it basically severed his upper half from his lower. And that was just Bird Shot.
I have no doubts about the effectiveness of a shotgun at close range. I did not know that the projectiles could create an audible sonic boom. So thanks.
