Both my 34's had twang. I put a JM GRT kit in my .22 34 730fps with 14 grain. No buss now! My other .177 I used JM's 12ft lb kit 790's with 8.65. Very smooth easy cocking and just a great shooter.Congrats on your new german girl! Looking forward to pic's Dustin
Well depending on the condition of the seal and spring, your gun could be putting out good power, closer to the 900 than 700 fps. Since your gun is 20 years old, I would opt for the Leapers UTG droop compensating mount. That rifle will more than likely have some droop.Nathan
