I chose 41-50. I practice with my drenalin out to 65 and shoot consistantly. However we all know that actual deer hunting does not give you the same scenario. Heart pounding, usually 3 second window, and so on. So I feel comfortable out to 50 yards if I absolutely have to. Most of the time, I only plan on up to 35 though when hunting and go from there with the different situations. For instance, mule deer hunting presents a lot of further shots with open terrain.
