i dont know much about my bow, besides that it is a martin, and on the limb it says firecat and proseries, i dont know the pull weight but im trying to get a friend into shooting the bow, and she cant pull the weight yet, and im guess guessing its about 55 pounds or so. i read elsewhere that you adjust weight by the screws on the end of the limbs, but only so many turns past full weight. so should i tighten the screws all the way and the let it off little by little. or is there another method to do this. thanks for the help
