What guns has the 50 .cal bullet besides the barrett?

the WW2 BREN was a 50 cal heavy machine gun

A few pistols, the Desert Eagle 50AE and Smith & Wesson 500 both fire a .50 cal bullet.

And the Browning M2 is a machine gun that fires the same powerful .50BMG that the Barrett uses.

The M60 is not a 50 cal. It is .308

well lets start with the M2 .50 cal machine gun, and all its variants, the electric .50 on the avenger and OH-53 kiowa, the other .50 cal sniper rifles besides the barrett.

Having asked this question TWICE now, and with friends who seem unable to grasp the concepts of physics as they relate to ballistics, you stink of troll. Here's your answer: It is so that dragon skin bullet proof wears not will stop the .50 cal bullet fired from Barrett M107 becuase energy created by velocity of .50 cal bullet much higher than dragon skin designed to withstand. Body inside vest turned to goo from impact of .50 cal bullet even before penetration. Tell your friends to go back to school and learn something.
