About this Video:

The Gamo Magnum GR is a great shooting springer so the kind of tune I want to do is perfect for it. Tune In-A-Tube, it takes a decent spring gun and makes it better. At least that’s what they say, I wasn’t sure what to think at first, now I get to check it out. What will it improve? Accuracy, vibration/sound, velocity, cocking effort? I guess you’ll have to watch and see.
