need more info............what is your draw length? What lenght are your arrows? What grain tips are you shooting? What do you have on the string? Brass knocks, string loop, leaches, whiskers....................everything makes a difference. Just off hand, I bet you are looking at the IBO speed of the bow which is at 300 fps.....................well that is at 70#'s with a 30" draw length and you aren't pulling quite that far, maybe in the 28 inch range?
