So what you think the new 82n't airborne shoots its advertised speed rating?
Few bows do make IBO these days. What would be the point of posting a speed I made up? I will go with the factory specs thank you very much. I also don't consider the speed ratings of this bow those of a speed bow. My son shot the bow at 27 inches with PSE carbon force 200 arrows and 60lb of draw weight at 264fps oh and now I would need to add that that was with an STS on it and a peep and two brass nocks and on and on we go. Is this worth the effort or would we be better off to just post the factory specs?:dizzy: Oh by the way there is no way these bows won't shoot over 300fps.
