Heres where you need to be shooting I have circled the heart in black and outlined the lungs in green, this is the kill zone. Why are you aiming so far forward and high??? Are you bending at the waist when you shoot. Are you shooting from an elevated treestand. If you are. Aim lower than where you want to hit. Also another thing to keep in mind, if youre going to hunt from an elevated stand, practice from an elevated stand at the same height. Theres no excuse for a lost/wounded deer. Practice, Practice, Practice....is the key to success.
