You of course replaced your original bolt that came in the .22 right? On your Vol. barrel in tiny print is the warning. The .17 requires a heavier bolt that delays the bolt opening and has more mass to take care of the added pressure that your "new" .17 Mach 2 develops.
How do you know if you have the right bolt in or not you ask?
Take your bolt out and turn it over (bottom side of bolt) and see if it has a flat piece of steel (titanium) I believe. No flat slab on the bottom of your bolt then don't shoot .17's until you get the proper bolt. You know first hand the results otherwise.
