my cougar fc with xt cam made a click on full draw tonight, and the vibration popped the arrow off the string . I let off and found the string frayed where it looked like it was rubbing on the cam. It wore through the serving and thought that was the pop I felt. Put in a press and checked cam alignment and for looseness and found nothing out of line or loose. took it out and drew it a couple more times with the same pop.
any ideas on what it may be? At rest everything looks normal. I have the cams set at -10 and bolts out about 4 turns to 53 lbs for shooting indoor target since new. it about 2 mos old with less than a 500 arrows thru it.
