Abstract

An improved telescopic gun sight includes a telescopic gun sight at least including an adjustable lens configuration for adjustably magnifying an external object to form an object image, an inverting tube for inverting the object image, an ocular lens array for presenting the object image for viewing, a primary reticule including sighting insignia imprinted thereon and a secondary reticule being movable both horizontally and vertically in the image plane. The secondary reticule includes a generally horizontal windage correction scale operative to provide instant windage correction target alignment. It includes instant windage correction target alignment values positioned at point-specific spaced-apart locations with specific instant windage correction target alignment values corresponding to selected distance amounts calculated for a selected bullet type and weight.

Claims

1. 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.

2. The telescopic gun sight of claim 1 wherein said inverting tube further comprises a plurality of adjustable lenses operable to magnify the object image up to a maximum magnification power, and wherein said generally horizontal windage correction scale is imprinted on said secondary reticule in a position such that when said adjustable lenses magnify the object image to the maximum magnification power said generally horizontal windage correction scale is no longer visible through said ocular lens.

3. The telescopic gun sight of claim 1 wherein said instant windage correction target alignment values are integer values selected to correspond to the distance from said housing to the object image in one of meters and yards divided by one hundred.

4. The telescopic gun sight of claim 1 wherein said generally horizontal windage correction scale further comprises a series of marks positioned at said point-specific spaced-apart locations to clearly delineate said point-specific spaced-apart locations each of which corresponds to a selected distance calculated for a selected bullet type, bullet weight, and wind speed.

5. The telescopic gun sight of claim 4, wherein said marks comprise dots.

6. A 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.

7. The reticule of claim 6, wherein said reticule is configured for use in a telescopic gun sight operable to sight an object image, and wherein said instant windage correction target alignment values are integer values selected to correspond to the distance from the gun sight to the object image in one of meters and yards divided by one hundred.

8. The reticule of claim 6, wherein said generally horizontal windage correction scale further comprises a series of marks positioned at said point-specific spaced-apart locations to clearly delineate said point-specific spaced-apart locations each of which corresponds to a selected distance calculated for a selected bullet type, bullet weight, and wind speed.
