That OK, in fact all bows will shoot their peak performance at their peak draw weight. By screwing the limb bolts in all the way puts you at peak or slightly over peak which is OK. My bow draw weight is 60lbs and I am set at 62lbs. Take your bow to someone who has a draw weight scale and see what you draw weight is. If you have a deer scale used fro weighing deer you can use that.

good luck
