One of the best videos regarding psychoanalysis that I've ever seen.

Will make it a point to watch it again.

Oh yes, Scientology is a dangerous cult founded by a psychotic science fiction writer based on psychoanalysis (Freud), hypnosis (Erickson), general semantics (Korzybski), and ritual magick (Crowley). Since his death, the bogus "system" has since been sifted into marketing tools as a sort of pyramid scheme of insane brainwashing programs. If but its members could break trance long enough to realize how self-deluded they are to see, thanks to this video, the extent to which All Scientologists have blood on their hands (even Tom Cruise, despite the fact that TCLTC).

Fake this, trash that, ballistic calculations blah blah blah...you people are LAZY. This isn't Youtube, folks, do the math if you're gonna complain so much.

First of all, a quick Googling reveals this gem:
"6-27-07: BOOM HEADSHOT! This is amazing. Willie, the father of Tina, who made the sandbag rests fires a .50BMG, an Armalite AR-50 and it ricochets off of a steel plate that it should have easily penetrated. The bullet comes straight back and hits him in the head. You can see it hit the dirt about 15 feet in front on him before it clobbers him. Luckily he was uninjured. He's a bit sore today, but otherwise fine. Lucky lucky bastard. He has been advised to buy lottery tickets while he still has so much luck. I don't know about the timing, but you can hear the hit on the steel plate. Time that till the impact on Willie's head... how fast is that 750 grain slug traveling? The range is 100 yards. Amazing."

The time from the sound of the shot to the sound of the impact of the bullet on the target is used to calculate for the initial velocity (sound delay over distance accounted for). The speed of the projectile (I'm not ruling out the possibility of a piece of the target being the ricochet, not the bullet) on ricochet to the ground is taken from the time from the sound of the impact of the bullet on the target to the sound of the impact on the ground. The speed of the projectile on ricochet to the earmuff is taken from the time from the impact on the ground to the impact on the earmuff. (This last impact makes a rather significant change in energy loss.)

For the sake of better accuracy, I assumed that the range was NOT 100 yards and calculated distance instead assuming that the gun was an Armalite AR-50 (.50 BMG), 750 grain slug, and that certain ballistic statistics on the gun were reasonably accurate, and that the ricochet did not return straight back, then compared the expected and actual times between the round being fired, the impact on target, impact on dirt, and then impact on person.

Keep in mind that I am no expert on large-caliber rifles and these calculations are the result of about 5 minutes of thinking, but unless you're willing to properly time the sounds on a video editor, incorporate angling for the energy transfer calculations and cross-reference ballistics info on the AR-50, I'm the best you're gonna get, so piss off.

Bullet weight: 750 gr
Average muzzle velocity: 2620 ft/s
Average energy: 11420 ft*lbf

Distance to target: 362 ft
Muzzle velocity of shot: 2603 ft/s
Velocity of the projectile on impact to the ground: 271 ft/s
Velocity of the projectile on impact to the earmuff: 210 ft/s

Conclusion: Very possible, especially assuming the target was steel, as I quoted above, but contrary to what the guy in the video said.

For reference sake, this is less than the speed an average paintball will hit you at (I think 250-300 ft/s). In all likelihood, though, the projectile had enough speed and energy and pointy bits to seriously mess this guy up if he'd been hit straight on. Maybe there'd be enough pressure to penetrate, maybe not, but I'd bet he'd have a broken bone or two at the very least.

On a final note, ricochets do happen with metal targets, and not completely rarely either, thus the rules of gun safety. This guy should NOT have been shooting at a steel/iron target with a .50 caliber rifle at such a close distance (I've heard that .50 cals can hit targets a mile and a half out), although it seems like he was smart enough to be wearing eye protection. He made the assumption that the round would penetrate the target, and we've all heard what happens when you assume. Hell, I can't even think of a reason to OWN a .50 caliber, past a psychoanalysis to make Freud weep or dreams of zombie pandemics.

Anyways, lucky guy, one-in-a-million-chance, remember gun safety, and you're welcome.
