Aim for the boiler room and leave the head and neck shots to the greenhorns. Much bigger kill zone, maybe 10-15 inches. In hunting you can only control so many of the variables so aiming for a " 3" inch target really isn' t a good idea. The general public is still trying to make up its mind on hunting. Leaving wounded animals only hurts our cause. Not saying aiming for the heart and lungs is always perfect, just plain smarter.
