I thought that rabies was transmitted in saliva and cerebro-spinal fluid. The old-timers always told me, "aim for the heart, not the head." Anyway, if you get checked for rabies, get checked again a few months on, and again after. It is a virus, so anti-biotics will not help. Around here (NE USA), we just burn 'em where they fall, if possible.
EDIT: What's a 766? Is that like the 2100/2200 rifle?
