impulse = change in momentum = force (= mass bullet x velocity and then use similar units , g = M/s/s , velocity = metres/s , foot size = metres)
standing position = weight balanced over fulcrum of foot ( 'bigfoot' has a better result here ... )
bullet impact height above ground contact point x force of bullet = weight (being) x fulcrum
as bullet approaches cannon ball size, additional possibilities amount to position of impact relative to c of g, direct hit at c of g - results in immediate lateral displacement after subsequent collapse around ball
a further displacement from c of g could create a moment = force and eccentricity, force sufficient to move body / peices, and eccentric load imparting a spin, so it would then spin off into the distance
advised not to try this at home...

They use armor piercing bullets to go thru metal. I'm sure in the film they were using lead bullets. I'll look for the video.

Originally posted by AThousandYoungIt'd shred through the thickest phone book in the world and go through 2 or 3 men behind it. Hollow points generally don't expand when hitting dry paper, the paper plugs up the hollow point and prevents any expansion. Even if it did mushroom, it'd go through a phone book and at least one guy on the other side.
