L,
I'm gonna hafta check time of flight on that particular bullet out of a .375H&H AI.
I think that critter just fell over dead knowing it was you shooting and it was gonna die anyway.
Died of respect...
It must have taken it awhile to figure out who the dude with the gun was.
I figured it would just stay down from its nap and die while still on the ground if it had known it was kamo_gari walking up on it.
