My Swarovski scope with a TDS reticle comes with a booklet that has a good list of different game with body size and explains how to calculate distance
Great in theory,but even whitetailed deer range in size from 150lbs to over 300lbs,and elk from 400lbs to over 800lbs,so the system can never be nearly as accurate as a laser rangefinder.At 500 yards,it doesn't take much error to make the difference between a clean kill,and a wounded animal.
