I'm shooting every time in the situation given. I started a thread just like this one a couple of years ago. If you can hit a 2 liter bottle turned on it's side at whatever the distance then you can drop that buck every time. You just have to remember to shoot high in the pelvic cavity and spine. Straight away is the one that has a very small margin of error,which is basically the base of the tail and I'm not taking that shot.
