Yes, a body hit with a bullhead just bounces back. A dead center hit in the wattles will bounce back as well... I've killed 30 or so birds with a bow, body shots- even hit perfectly can still run or fly great distances. I've had 3 that I cut the spine in half between the legs and wings still get airborne and fly a couple hundred yards before dying.. The neck and head are as big as the internal vitals, you can see them and when you miss, you just miss. A miss by an inch or two body hit is a wasted bird with a standard broadhead.
When you miss with a bullhead you don't lose the arrow. I miss a lot...
