Sonic Boom effects?

[Crosswind]

Hi everybody, just a though experiment.

Wondering if supersonic bullets have any measurable effects on handgun recoil.

For starters:
Speed of sound in dry air at 20 Celsius = 1126 ft/sec
Speed of sound in dry air at 0 Celsius = 1087 ft/sec

Assuming you're shooting a load that averages 1100 ft/sec, would there be more perceived/actual recoil when shooting in warm weather compared to shooting in cold weather?

And yeah I know you can just choose to shoot a load that averages below 900 ft/sec and completely ignore this issue, but again, just a though experiment.

If anything there may be more or less percieved/actual noise depending on the temperature. But I believe the recoil would remain constant as the velocity of the round has not changed, therefore the physics (ever action has an equal and oposite reaction) have not changed.

The temperature will change the muzzle velocity.

My GF prefers Subsonic loads in the 9mm.
Less barky.

This.

Flight noise has nothing to do with recoil.

Way more noise with supersonic but recoil has nothing to do with this, if there is a dif. it's prolly so small as to be not measureable.

Recoil is a function of the combination of bullet, propellant, and gun weight. A .44 magnum loaded with 325 gr bullets at 900 fps from a 3 pound gun, will certainly recoil more than a .22 Remington Jet, firing a 40 gr bullet with a muzzle velocity of nearly 2000 fps from a gun of the same weight. Conversely, the more propellant that is put into any given cartridge, with any given bullet, and fired in any given gun, the greater the recoil will be; independent of velocity.
