My Terminator started stringing arrows while practicing last week, sending one into several layers of wood and a truck mud flap backstop. Sure enough the bolts holding the trigger guard to the scope base had loosened. It had happened before but I thought it was fixed by loc-tighening (blue) it. It had stayed in place for at least a hundred shots but loosened again; even with thread lock. (Got to admit tho I didn't use that much for fear of making it permanent). Words to the wise: check them bolts.
