the last elk bulls and cows son and i have shot were with Elmer heads now called Sevr this is an expandable head and works very well ,i have in the past used other expandable broadheads they did not kill the bulls that fast . my 1st bull was with a Zwickey Eskimo 125 gr. that broadhead is a great cut on impact if you shoot a slower bow and have the ability to sharpen a broadhead . good luck , Pete53
