That was going 3150fps at impact. Which is to say, pretty close to (if not actually) muzzle velocity. From a 20" barrel. My neighbor from down the street, who I talked to while he was on leave, was decidedly less than impressed with the results of shooting an Iraqi in the chest five times with his M4 firing M855 at under 150 yards. And by "decidedly less than impressed" I mean "swearing profusely".
Personally, I'd rather hit someone with the bullet on the left.
