Patent ID: 7836626

Claim:
A telescopic gun sight for sighting an image of an object, comprising: a housing comprising an objective end and an eyepiece end; an objective lens positioned within said objective end, said objective lens operable to receive light from the object and focus the image of the object at an image plane positioned between said objective and eyepiece ends; an inverting tube positioned between said image plane and said eyepiece end for inverting the object image; an ocular lens positioned within said eyepiece end for presenting the inverted object image for viewing; a primary reticule positioned between said ocular lens and said inverting tube, said primary reticule including sighting insignia imprinted thereon; and a secondary reticule positioned between said inverting tube and said objective lens, said secondary reticule being movable both horizontally and vertically in said image plane independent of said inverting tube, said secondary reticule comprising a generally horizontal windage correction scale operative to provide instant windage correction target alignment, said windage correction scale comprising a plurality of instant windage correction target alignment values positioned at point-specific spaced-apart locations on said windage correction scale, wherein each instant windage correction target alignment value corresponds with a selected distance calculated for a selected bullet type, bullet weight, and wind speed, said windage correction scale eliminating the need to calculate the horizontal deflection of a bullet due to wind and the minutes of angle corresponding to the horizontal deflection.
