What is the Range of a barrett 50 caliber rifle?

it depends on the weather but on a clear day it can travle up to 1/2 miles but normaly1 mile.

When shooting a barret 50. cal you have to remember that the bullet your shooting weighs more than a standard flak jacket it drops like a dead pigeon at a range of 400 ft. if you took a shot from a mile away the bullet would drop about 10 feet more than a standard sniper rifle and carry more force than a 44. magnum at point blank you could put a bullet through three men before the bullet dropped far enough to hit the ground. If i was taking a long shot i would use a Cheytac intervention it has the one of the longest accurate range on a modern day sniper rifle about 2.3 km or 2,500 yards it is reliable and can take out a wide variety of targets.
