I am trying to help a friend set up a bow that he got from someone. the sticker tells me the draw is 30.5 to 27.5. he should be at a 28 inch draw. when i take the bolt out of the draw mod and move it to what should be 27.5 its really at 29 inch. I dont know the year of the bow but it is a ZR200 with a VP2R cam and the draw mod is a #2. i didnt think there was any other mods neede for a hoyt but the one that was on it. can anyone help??
