bounce off of pavement, glance along, would be more the word, and still DEEPLY dent a sheet metal door. The military considers just piecing a 1" pine board to be the minimal level for "lethality". Some "think" that a pocket .22 wont pierce temple, facial, or base of skull bones, but they are incorrect. At least, they are if the angle of impact is 90 degrees. .45's have been known to glance off skulls, too, you know, if the angle of impact is "shallow" enough.
