i shot my hoyt deviator (carbonite limbs) on my college's archery team last year. we were outside practicing at 90m one day and when i touched the shot off it *sounded* like a dry fire. it scared the daylights out of me.

went over to the spotting scope and it was a 9 though. i still have no explanation for what happened, but i took it to lancaster archery immediately and they checked it out and ok'd it.
