1. A telescope sight for sighting-in and aiming a firearm, comprising:

  • objective lens means for presenting an object onto an image plane;

    inverting tube means positioned relative to said image plane for inverting the object image appearing in said image plane;

    occular lens means for presenting the inverted object image for viewing;

    a primary reticule for constantly defining the center point of the field of view of the sight for defining a first aiming sight position through the telescope sight, said primary reticule positioned at and in a fixed relationship with one end of said inverting tube means, said one end being the end disposed more distally from said image plane;

    first adjustment means manually actuable for positioning the other end of said inverting tube means relative to said one end, for adjusting said first aiming sight position of said primary reticule relative to the bore of the firearm;

    a secondary reticule located at said image plane for establishing a reference point which defines the relationship of the primary reticule to the bore of the firearm, with respect to which said first adjustment means may be actuated for aligning the reticules to sight-in the firearm, said secondary reticule being movable both horizontally and vertically in said image plane independent of said inverting tube means; and

    second adjustment means for moving said secondary reticule relative to said primary reticule for establishing said relationship.
