if you do testing and you find the set up is boarderline...close to 150...try useing smaller fletch....that will make a big difference as far as more distance down range......i dont have any clue how far a 42 pound bow will shoot an arrow at any weight....i would think 150 yards would be close if not well within reach.......if you test it let us know how it shoots...now i think im gonna do my own testing when i get a chance
