Main Question or Discussion Point

What, other than recoil, the user's unsteady hands and gravity, causes bullets to impact different places on the target?

Things which might influence the bullet:
- Air conditions (wind, ...)
- Imperfections in the ammunition
- maybe the temperature in the weapon (as it can expand parts of it), which can increase during its use

Gravity should be the same for all bullets.

Why is velocity often said to increase accuracy? Because it can go further before being blown off course or dropped?

Higher velocity -> shorter flight time for the same distance.
It reduces the time for air and gravity (and probably other effects) to modify the path.
