I'm shooting a 423 grain arrow at 70#, 290fps, using a 125 grain tip. now when I shoot my 125 Thunder heads my arrow flight will significantly drop out past 20 yards and vear a little right and obviously get worse the farther out campared to my field tip...?? Is this a tuning issue or b-head issue? I would say my bow is tuned good with the groups I can shoot normally....
Is it just to fast for fixed blade?
