This is a .50 cal. The projectile makes the round trip b/t/w the gun, a steel target 1000 meters downrange, and the shooter's ear protection. Out and back, and if it'd been an inch to the right homeboy would be dead or breathing out of a tube.
Danger close with the .50 cal is anywhere within earshot - and some places out of earshot. Pretty hella sick invention for a pacifist mormon dude.
