My first bowkill last year was both lungs and cut the arteries coming off the top of the heart. He didn' t make it 10 yards. I' m glad he didn' t run, because there was very little blood, because as David pointed out in the post above the blood was pumping into his chest and not into the rest of his body. My bowkill this year was one lung and straight through the heart! It was a steep angle and the arrow exited the brisket. The blood trail was awesome because the blood in his chest was leaking out the hole in his brisket. He made it 40 yards.

PS. Now I have a cool heart shot pic like David!!
