I have hunted with a compound bow for many years and recently took up the challenge of using a Longbow. After finding the proper arrow, spine and weight, decided to see what my combination was producing in kinetic energy. The combination is very accurate yet only produces 32 lbs of energy at best. I shoot a 57lb Tomahawk @28″. I use 568 grains total arrow weight, with a speed of 158 or so. Is this enough for Whitetail ? Is there a better combination ? I realize shot placement is ” almost everything ” . I guess I was expecting more KE. Any advice would be greatly excepted. Thanks, Tim
