Have shot and seen elk shot with a variety of heads, and they'll all work with a broadside shot to the ribs. However, if you happen to hit heavy bone, listen to Dr. Ashby and shoot a single-bevel 2 blade for your best odds! Compound shooters seem to disregard his advice, but it's by FAR the most sound evidence as to the best broadhead choice for the highest chance of a lethal kill on large game. Cutthroat Broadheads are the best single bevel, made by VPA.
