yes, if you shim a two piece the scope rings won't be in perfect alignment w/ each other, and it will torque on the scope tube. Badger or Nightforce makes the best one-piece.Sorry If this is a hijack. I'm new here by the way. Wouldn't the action/scope be more solid with a 1pc. canted scope base? I'm not sure I understand why you would use shims. thanks for info. Great website by the way.
here is my question ,what os the best way to set a scope up for long range shots. i have heard several things from shimming to special rings .suggestion please
