The thirty feet per second per second that Susan refers to, is the acceleration due to gravity, not the terminal velocity.
One mph equal 1.66 feet per second; 30 fps is about 18mph.
I seem to remember that a human's "terminal" velocity is approx 120 mph. I don't know what kind of velocity to expect from a bullet in freefall, but I'd expect higher than that, given the density and drag. YMMV
