with a bow u have to go for the heart/lungs but with a gun it all depends on what youre shooting at if its a buck never shoot it in the head cuz you can mess up the rack or mess up a mount if ur gettin it mounted. Now Does one the other hand id rather put one in the head with a gun so that way no meat is ruined and if u miss its not that big of a deal because Does are soo plentiful
