This film was shot in a quarry somewhere in the USA - in hindsight they should have picked a better spot to test the power of this gun.
Thankfully, the bullet lost most of its momentum on its return journey, bouncing off the floor a few feet in front of the shooter and striking him on his ear muffs, ripping them off his head.
His friend is heard saying, in a classic southern-American accent: "That's the last one o them we're doin"
We don't blame them!
We also think the shooter should be buying a lottery ticket on the way home!
