1. A method of correcting the cant of vertical and horizontal cross hairs in the reticle system of a sighting scope attached to a firearm having a receiver section with a flat portion oriented perpendicular to the vertical axis of the receiver section, and comprising the steps of:placing the firearm sighting scope in a condition whereby it may be rotated about its longitudinal axis;mounting a horizontal level assembly on the flat portion of the receiver section transversely to its longitudinal axis;rotating the firearm about its longitudinal axis until the horizontal level assembly indicates the firearm transverse axis is level thereby causing the firearm vertical axis of symmetry to be in a true vertical condition;locating a vertical reference distant from but in alignment with the firearm sighting scope;rotating the firearm sighting scope about its longitudinal axis until the vertical cross hair of the reticle system is in alignment with said vertical reference; and placing the firearm sighting scope in a condition whereby it may not be readily rotated about its longitudinal axis. 2. The method of claim 1 wherein said horizontal level assembly comprises a bubble level mounted on the flat portion of the firearm receiver transversely to the longitudinal axis of the firearm and wherein the vertical axis of symmetry of the firearm is positioned in a true vertical condition when said bubble level indicates a horizontally level position. 3. A method of correcting the cant of vertical and horizontal cross hairs in the reticle system of a sighting scope attached to a firearm, and comprising the steps of:placing the firearm sighting scope in a condition whereby it may be rotated about its longitudinal axis;rigidly positioning the firearm with its vertical axis of symmetry in a true vertical condition;locating a vertical reference distant from but in alignment with the firearm sighting scope;rotating the firearm sighting scope about its longitudinal axis until the vertical cross hair of the reticle system is in alignment with said vertical reference;placing the firearm sighting scope in a condition whereby it may not be readily rotated about its longitudinal axis;wherein a bubble level is mounted on a flat portion of the firearm receiver transversely to the longitudinal axis of the forearm and the vertical axis of symmetry of the firearm is positioned in a true vertical condition when said bubble level indicates a horizontally level position.
