Ignorance may be bliss, but common sense is not.
The Maximum effective range of the .50 BMG round is 2,000 yards; Maximum range is 7,140 yards. Or 21,420 ft. Which is 4.06 miles (5,280’/mile). This assumes 647g FMJ ammo.
Specific data:
Initial Angle: 36.3 deg Terminal Angle: 62.9 deg
Terminal Range: 7140.0 yds Terminal Velocity: 585.2 ft/s
Terminal Time: 38.397 sec. Terminal Energy: 491.9 ft•lbs
If shooting .50BMG AMAX Match Ammo (from a bolt rifle), the BC is much better so the Maximum range would be 8,820 yards. Or 26,460 ft. Which is 5.01 miles (5,280’/mile). This assumes 750g AMAX Match ammo.
Specific data:
Initial Angle: 37.5 deg Terminal Angle: 61.5 deg
Terminal Range: 8820.0 yds Terminal Velocity: 677.4 ft/s
Terminal Time: 42.799 sec Terminal Energy: 764.0 ft•lbs
Maximum Distance - Maximum distance achieved.
Initial Angle - The angle of the barrel relative to the ground.
Terminal Range - The distance achieved by the bullet for the elevation.
Terminal Angle - Angle at which bullet strikes the ground. Ninety degrees is straight down.
Terminal Velocity - The final speed of the bullet in feet per second
Terminal Energy - Really the "Kinetic Energy" of the bullet. The kinetic energy is a measure of the maximum amount of work (force time distance) an object can do. [It is also a measure of the work done by the firearm/case/primer/powder on the bullet.]
Time of flight - The time of flight of bullet in seconds.
Given the above, it would be possible to kill something at the Maximum distances indicated.
