Young Buck, I have killed an Elk with a bow set at 65 pounds using standard broadheads. Complete pass through on one and the second was all the way through but the broadhead did not penetrate the skin on the far side. The set up you are proposing should work just fine. Just get close, pick you spot and let her fly. Good luck. Bow hunting is for elk is both the hardest and at the same time the most rewarding hunts I have ever made. Traveling Man
