I guess I'll be the one to respectfully disagree
Elk are big, very tough creatures. Can you use a 165 Accu Bond to take one? Under the right circumstances I would think so. The problem is that while hunting to many times the circumstances are not right, something changes at the moment of the shot. The question should not be can you use it but rather if you do and something goes wrong, and you lose the animal, are you going to be wishing you would have gone with a better constructed or heavier bullet?
