I know a dedicated hunter in Hawaii that has one and it's one of his favorite airguns, if not his very favorite airgun. He has several, too. He hunts and kills all sorts of stuff (impressive stuff) with it all the time. When I buy a .22, the RainStorm is going to be the one. Maybe he'll pop-in here for a visit.
Let me know if you ever want it tuned to perform even better! I know a great tuner for the RainStorm.
