8mm/06 is right back on page 2 of this debate. It's a combination of velocity and mass. You can't argue that it's just velocity, and that power doesn't exist, because you are wrong. Velocity and mass together great a FORCE, or power. One without the other leaves you with either a near massless object moving at extremely high velocity (but delivers no force), or a motionless mass (again, no force). I don't see what's so hard to grasp here folks.
