When I first started bowhunting I took a buck with that shot he never took another step. I was on the ground and he raised his head to lick a branch while making a scrape, second time he did it a buried an arrow in him middle of the chest, he dropped right there. 15-18 yards away he acted like a train hit him. Reared back on his hind legs and and almost did a flip.

Haven't had the same oppurtunity on another one like that since, but I'll tell you what, it was allmost an an immediate kill.
