had the same experience with their Gamos! Your report ALMOST makes me want to buy another "440" to see if I'll have better luck. I felt that perhaps getting a "good" Gamo was simply "luck of the draw" due to my experience with a few, but then I read glowing reports like yours that are contrary to my experiences (and others). LOL, if my Gamo experience was even CLOSE to my HW experience I would have been tuning Gamo's rather than R9s!
Oh well, the "different strokes for different folks" saying isn't just a platitude in this case!
