One of my first bow kills, I shot a doe and got one lung and the liver. The arrow had a narrow broad head that was extremely sharp. The doe jumped a step, looked around, arched her back, and licked the exit wound ... no ribs touched. She walked about 60 steps, and laid down. She looked around - laid her head down ... looked up again, laid her down and she was gone. She never acted like she was hit and bleed out rapidly, going to for ever sleep without spooking. Broad head was about 1 inch wide by 2 3/4 inches long. Not much of a blood trail, she bleed almost all inside, but I watched her go down and she never moved.
