Most people do not armor the head or groin areas. Obviously a head shot is a show stopper. However don't forget about the groin. Breaking the pelvis girdle or severing the femoral artery will put him down pretty quick as well. Shot placement is the key.....or you can keep moving up from a .500 to RPG to a Stinger. I vote for shot placement.
Although you will probably not be walking around with a shotgun, but if available that would be my choice. If you can hit a clay target on the move you most likely could hit a head size target w/ 00 if given the shot. Also a slug to the chest will leave a mark even w/ body armor. Same point as above for a pelvis shot w/ 00.
