You are only getting about 230 fps. The IBO on that bow is 295. You would get 295 fps by having a 30" draw, 70 lbs, and a 350 grain arrow. If you want to shoot 300 fps you need to pull 70 lbs, 31" draw, and a 350 grain arrow, or you can pull 80 lbs, 30" draw, and 350 grain arrow. Either way, you won't get 300 fps with that bow.
