Abstract

A 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 windage correction system for a telescopic gun sight comprising:

a telescopic gun sight at least including an adjustable lens means for adjustably magnifying an external object to form an object image, inverting tube means for inverting the object image, ocular lens means for presenting the object image for viewing, a primary reticule positioned generally adjacent said ocular lens means rearwards of said inverting tube means and including sighting insignia imprinted thereon and a secondary reticule being movable both horizontally and vertically in said image plane independent of said inverting tube means and positioned forward of said adjustable lens means; and

said secondary reticule including a generally horizontal windage correction scale operative to provide instant windage correction target alignment and including instant windage correction target alignment values positioned at point-specific spaced-apart locations on said generally horizontal scale with specific instant windage correction target alignment values corresponding to selected distance amounts calculated for a selected bullet type and weight.

2. The windage correction system for a telescopic gun sight of claim 1 wherein said generally horizontal windage correction scale is imprinted on said secondary reticule in a position such that as said adjustable lens means increases the magnification of the external object towards its maximum magnification power, said generally horizontal windage correction scale is no longer visible through said telescopic gun sight as said generally horizontal windage correction scale is outside of the view field of said telescopic gun sight.

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

4. The windage correction system for a telescopic gun sight of claim 1 wherein said generally horizontal windage correction scale further comprises a series of dots positioned at said point-specific spaced-apart locations to clearly delineate said point-specific spaced-apart locations corresponding to selected distance amounts calculated for a selected bullet type and weight.

5. A windage correction system for a telescopic gun sight comprising:

a telescopic gun sight at least including inverting tube means for inverting the object image, ocular lens means for presenting the object image for viewing and at least one reticule positioned generally adjacent said ocular lens means rearwards of said inverting tube means and including sighting insignia imprinted thereon; and

said at least one reticule including a generally horizontal windage correction scale operative to provide instant windage correction target alignment and including instant windage correction target alignment values positioned at point-specific spaced-apart locations on said generally horizontal scale with specific instant windage correction target alignment values corresponding to selected distance amounts calculated for a selected bullet type and weight.

6. The windage correction system for a telescopic gun sight of claim 5 wherein said instant windage correction target alignment values are integer values selected to correspond to the distance from target in one of meters and yards divided by one hundred.

7. The windage correction system for a telescopic gun sight of claim 5 wherein said generally horizontal windage correction scale further comprises a series of dots positioned at said point-specific spaced-apart locations to clearly delineate said point-specific spaced-apart locations corresponding to selected distance amounts calculated for a selected bullet type and weight.

8. A windage correction system for a telescopic gun sight comprising:

a telescopic gun sight at least including an adjustable lens means for adjustably magnifying an external object to form an object image, inverting tube means for inverting the object image, ocular lens means for presenting the object image for viewing, a primary reticule positioned generally adjacent said ocular lens means rearwards of said inverting tube means and including sighting insignia imprinted thereon and a secondary reticule being movable both horizontally and vertically in said image plane independent of said inverting tube means and positioned forward of said adjustable lens means; and

a generally horizontal windage correction scale imprinted on one of said primary and secondary reticules, said generally horizontal windage correction scale operative to provide instant windage correction target alignment and including instant windage correction target alignment values positioned at point-specific spaced-apart locations on said generally horizontal scale with specific instant windage correction target alignment values corresponding to selected distance amounts calculated for a selected bullet type and weight.

9. The windage correction system for a telescopic gun sight of claim 8 wherein said instant windage correction target alignment values are integer values selected to correspond to the distance from target in one of meters and yards divided by one hundred.

10. The windage correction system for a telescopic gun sight of claim 8 wherein said generally horizontal windage correction scale further comprises a series of dots positioned at said point-specific spaced-apart locations to clearly delineate said point-specific spaced-apart locations corresponding to selected distance amounts calculated for a selected bullet type and weight.
