To test, do as Mr Horton describes above. If it doesn't move, then something else is wrong... not the tension of the screw.
I also believed that the screw should be bottomed against the shoulder. With the upper guards and nosecap removed I can loosen the screw and the inner band is free to move, rattle even. Tightening the screw will pull the muzzle noticeably upward.

If the thunderstorms stop I will try adjusting the tension of the inner band screw. Right now my backyard range requires a canoe to get to the targets 8^(

Thanks everyone for the info, very helpful.
