By "speed of gravity" I assume you mean terminal velocity[1].
If not fired fairly straight up the bullet can maintain a ballistic trajectory[2], rather than being in a vertical free fall. In that case, the higher speed compared to the terminal velocity is simply because it has yet to shed the speed it acquired[3] when it was accelerated out of the barrel.
