Is the desert eagle .50 cal or 50 cal and is a barret .50 cal or 50 cal?
First off, to explain Caliber- Caliber is a unit of measurement equal to a hundredth of an inch. If you put a decimal in front of the number, that would mean a fraction of a caliber, which is far smaller than the smallest of bullets. 50 caliber is equal to .5″. Of course, you could put a decimal in front, but then it would be a measurement of inches, not calibers. This is frequently done when barrel bores are referred to in 3 digit numbers, such as the .500 S&W. A 500 caliber weapon would have a bore 5″ in diameter. the 50 Action Express fired by the Desert Eagle (model of gun, produced by magnum research and IWI) is a 50 Caliber round. The 50 BMG (Browning Machine Gun) fired by various rifles, such as the Barrett is also a 50 caliber weapon, but it holds a larger volume of powder, which pushes a longer, heavier bullet to greater velocity than the 50 AE.
