I like your thoughts, Im thinking 7. Seriously, do we have to go over this again? All it does is turn into arguments. I've never in all of the forums we've had for this topic have anyone say "You've changed my mind". Search for "Head Shots" and you will days worth of reading. Personally, I saw a Jawless doe one time and even though I consider myself a very good shot I would never risk it. The look of that deer makes me a firm believer in heart/lung shots.
