I live in the mid-west so I have been limited to the number of times that I have been fortunate enough to have an opportunity at having an elk in my sights. Between myself and a hunting partner we have thrown arrows at 4 different elk. Half of those occasions allowed timing of us using our range finder. The other times we did not have that luxury. We are both productive whitetail hunters, we are not beginners at hunting. All of our misses have been low. Besides the obivous strategy of shooting higher. Is there a more general rule of thumb to help me be more productive at judging distance. Some of the shots have been uphill and some have been downhill, still waiting on that flat midwest ground shot, ha.
