i hit at 20 or under. everything else nose dives. but 20 and under are dead on. field points all shoot tight groups. i tried changing to inserts to line up blades with vanes and rotated all around. i tried different grain heads and brand news vs old. cant seem to get a good combo and i hate expandables for the simple reason of the rubberbands they use to stave off deployment. i shoot a martin 29" draw 60lbs
