The people that make bows know if they make fast bowssomeone wants a fast bow. My bow shoots around 272 fps with 407 grains an its going into the 5th season with me this year. I have my first pin at 17 yards. I judge distance after that an just shoot one pin. I know my bow an how much to raise it all the way out to 40 yards. I have no desire to shoot further than that matter of a fact never have shot farther than 27 yards at a deer.I do not need a bow that shoots350 fps with a 315 grain arrow.
