Haven't used it for hunting yet, still using my vertical bows, I have a Ravin R26. Very nice, compact, crossbow. As pete53 said, they are loud when shot, no doubt. The trigger in it is nicer than some rifles I've shot, very nice trigger system. I also went with Ravin's heavier arrows/bolts and 125gr expandable broadheads. I went with expandibles because the broadhead does stick out past the end of the crossbow and wasn't interested in exposed razor edges. I've shot it enough at targets that I'm now on its second set of cables and string. The R26 is my only crossbow experience and I am enjoying it, more than I thought I would. It's very accurate and very easy to shoot. I just might end up taking it for a walk through the woods this fall!
