DaveC, that shouldn' t be too hard. I shoot 70 lbs, a 2514 arrow that weighs 560 grains at around 230 fps and I' m at 65.796 ft/lbs. And that' s with soft cams. Any hard cam bow or single cam bow should be able to get you there pretty easily. Trick is, getting both speed, and arrow weight up there. Are you sure you' re not getting that kind of KE now?
