RE: field point vs. broadhead impact point
something is not right, either your rest/bow needs to be tuned again or maybe you are using a different grain fieldpoint than broadheads causing a change in your arrows spine which would result in the directional misses, however, at that distance you should not have any trouble. i would say a tuning rehaul is in order. Did you paper tune it at diferent distances? try it, it may surprise you ( 5 feet, 15, 20 ect)
