Is it bad to shoot a 70lb bow at 65lbs? Or a 60lb bow at 55lbs? Does it make the bow less acurate? I was told that you should shoot any given weight bow at its maximum. Does anyone have a 60lber they shoot at 55? Lets say (hypothetically) you have a 70lb that shoots around a 380 gr arrow at 310-315fps real chronoed speed. What would be a good fps estimate of the same model bow but a 60 lber with the same arrow?
