Never Heard of a vital hit on a deer that didnt bleed! I shot a button head with my muzzleloader (thought it was a doe) a couple years ago. Found hair EVERYWHERE. It was alot. No blood. Couldnt find the deer. Went to the nearest thicket and low and behold my trophy with a vital hit. Ive shot several deer with a gun and had them not bleed a drop until they hit the ground.
