derp: Mach 7 is 2 or 3 times faster than a modern rifle round.
JBSpesh: They have guided artillery rounds now that automatically correct their course. It's like a cross between a bullet and a missile.
Ducky: I think the writers for this site just misread the original piece. I think the original piece intended to say that the projectile could have gone 100 miles at the velocity it was at, not that it actually did.
