I have a beautiful Abbott longbow that is 53# draw @ 28. My shoulder can not pull that weight any more and I would like to reduce it to 48# to 50#. Any advice on the proper method to reduce the weight? Someone suggested slowly and carefully sand down both limbs evenly on the back side of the limbs. Not sure if this can be done or if it is a good idea. I want to keep the bow but just cant shoot it accurately at that weight. I need help!!!!!!!!!!
