I could easily end this argument by showing you what a .50 cal does to a human head, if you go to www.nwtactical.com,
you will see that it is run by a man named Matt Deeds, who was a sniper in the gulf war, I now him through his buissiness. He sent me a photo of a suicide bomber that was spotted by a sniper with a .50 cal in the green zone of Baghdad, the picture is enough to make you sick, becuase the contents of the bombers head are gone, and all that is left is ripped flesh of his face, but his body of course is intact. I no longer have this photo in my inbox.
My point is that a .50 cal round at long distances will not make a 150 pound man explode and fly upward like in that video you posted ice-is-scary, suffice to say what you say were two gun loving guys, that have bought .50 cal snipers (yes, they are legal) somewear in the US shooting large rodents, that were probibly under 20 pounds, and slight enough to explode when hit with a .50 cal round.
