If the action rocked in the chassis before adding the rear hold down then you still have a problem. With alot of the aftermarket stocks for the 10/22 the shorter TD screw from VQ takes care of this issue. When you get your new TD screw try installing the action without the rear tang first just to make sure. If it's still rocking then you are probably going to need to do some bedding. Even though the rear hold down makes it feel secure it's not and will probably have issues with consistent accuracy.
