Normally I don't like passing on links without (much) comment, but this one's too rich to pass up. DMFB from CinO does the arithmetic of a .22 to the nads vs a slapshot hockey puck to the same.
Pretty sure that my own maths are correct in my comment. If not, well, it's been 17 years since I took physics, although I'm still using the same calculator. Sharp EL-531A, best computating device I've ever owned, and all you Mathies with your graphing HPs can go piss up a rope -- mine cost \$10 at Zellers.
