nope, the velocity of a bullet when it returns to earth is quite different depending on the angle it's fired at. bullets fired straight up (at 90* to the surface) have expelled the muzzle velocity when they start falling back to earth meaning it no longer becomes part of the equation.
bullets fired at angles less than 90* still have the muzzle velocity included as part of the equation. the initial muzzle velocity of a bullet is greater than it's terminal velocity.
don't get me wrong, in both instances the bullets are travelling at a speed that can kill you, but the point is they are travelling at different speeds
