Its my nocking point. My serving has been un-winding, and I don't know how to fix it. I got a new string at the local shop, so I just need to go get that put on, and then I'll have it tuned up. Its just gotta get me thru till Nov 1, then I can get my new Hoyt going.
I would have just had the string reserved. But getting a new string, you'll want to shoot it a few hundred shots even before you tune it. If its a high quality string of 452, then 50 shots should do.
