Ok, just had a new string and cable installed on z7 extreme. Bow seems to be in spec and cable is running through timing hole. 26.5 in draw, 70lb limbs turned all the way down. (Not positive of actual draw weight) Arrow weighs 376 grains. Bow is shooting bullet holes through paper and seems to be doing well. The chrono shows 256fps. Using arrow speed calculators online it should be closer to 280fps. Is there something obvious I’m missing.
Not sure I am understanding %100 one part of your statement. “limbs turned all the way down”. So are you shooting at MAX poundage, or MIN poundage? I think you are saying max poundage, in which case your speed is low, by pretty much the 20fps Brian has listed for your bow being on 60lbs. If you are shooting 60lbs, then you are about right.
