Hi, Probably to avoid getting sued for not warning you. It is however an estimate and has a lot to do with the weapon it is fired from. Something fired from a pistol will not travel nearly as far as from a rifle. The longer barrel allows more time for the powder to burn and accelerate the bullet. Speed in this case equates to distance.
