Fairly meaningless discussion. I have had elk drop in there tracks with .308,44 mg,7 mag,50 cal ML, 30-30,30-06 and a few I can't remember. Distances were anywhere from 50 ft to 400 yards. AND I have had elk run 30-100 yards hit with the same cartridges .I have a half a baby food jar of 220 gr and 180 gr 30 cal. bullets( all C&C ) dug out of dead elk.
All these totaling in the 4 dozen dead elk realm. It is not what you hit them with, but where you hit them.
