For those of you that don't know the difference.
50 cal round next to a 7mm remington magnum round, i've killed elk with the 7mm, which usually run in the 800lb range. Human is on average less than 200lbs....hmmmm, yea a 50 cal will mess up a human pretty good, without even hitting them. I once heard that a 50 cal round only has to come within 4 feet of a person, and the force will rip off a limb.
