On the other end (for example) the M2 (50 cal machine gun) has a max range of 4.2 miles. A few yours ago in the DFW area a lady was killed walking to her car after church let out by a 50 cal bullet to the head. From the angle of the impact and direction, it was thought the round was fired from a field four mile away. The shooter was never identified.
