DId he say that 600 mph was faster than a 45 cal. bullet?

@theknightlynews Craig did say that, specifying a .45 cal. for a reason, though I had to do a little background research myself before that comment made it into the film. Turns out the .45 cal. ACP cartridge was designed to have a fairly low muzzle velocity, in part due to the weight of the slug (it's the mass that does most of the damage) but also because a subsonic bullet is far easier to silence, given the lack of a sonic boom when the bullet leaves the barrel.

@sciencehighway-Thanks for this post. Pure undiluted courage from Col. John Stapp.
