Point it barrel up and then barrel down and see if you can hear the lens sliding back and forth in the tube? If you can you definitely have a bad scope.
Also make sure your scope is fairly well centered. If your turrets are near the end of travel they may not hold the optics very securely.
I recommend an old Bushnell Trophy 4x12 for the 54.
