Hey, Brad, what pellets are you using, and do you have anything else you can try? I had a similar problem with an HW 77 and Crosman Premier pellets, the CFX I had was best with JSB Exacts and RWS Superdomes. I'd try some other pellets, if that doesn't solve the problem, send it back and get another one. Could be a too short chamber. Good luck.
