Although I have killed numerous animals at greater ranges. My self imposed limit is approx. 50 yards.
Knowing whether a shot is riight and/or makeable is much more than knowing the range. There are many factors that come into play.
Experience is ultimately the best teacher in shot selection situations.
The worst thing that can happen to a young hunter is to get lucky when he takes a Bad shot and kill that Deer. If he had wounded and lost that Deer he would have hopefully learned a lesson. Being successful while making a Bad decision usually takes more than one Bad experience before he will realize.............. Hey!! This is not a Good Thing!![8D]
