Abstract

The present invention relates to target acquisition and related devices, and more particularly to telescopic gunsights and associated equipment used to achieve shooting accuracy at, for example, close ranges, medium ranges and extreme ranges at stationary and moving targets.

Claims

1. A method for using a computer running a ballistics program, comprising:

a) inputting cartridge, altitude, temperature and atmospheric pressure data into said computer running said ballistics computer program;

b) calculating points of impact based on said data by said computer using said ballistics program;

c) selecting an aiming point on a reticle in a gunsight using said points of impact wherein said reticle comprises;

1) a primary vertical cross-hair;

2) a primary horizontal cross-hair intersecting said primary vertical cross-hair;

3) a plurality of secondary horizontal cross-hairs evenly spaced along said primary vertical cross-hair; and

4) a plurality of secondary vertical cross-hairs evenly spaced along at least some of said secondary horizontal cross-hair wherein said secondary vertical cross-hairs intersect one and only one secondary horizontal cross-hair;

wherein said aiming point on said reticle is projected by said ballistics calculator.

2. The method of claim 1, wherein said gunsight comprises a housing.

3. The method of claim 2, wherein said gunsight comprises an objective lens mounted in one end of said housing.

4. The method of claim 3, wherein said gunsight comprises an ocular lens mounted in an opposite end of said housing from said objective lens, wherein said reticle is mounted in said housing between said objective lens and said ocular lens.

5. The method of claim 1, wherein said reticle is constructed from an optically transparent wafer or disc.

6. The method of claim 1, wherein said primary vertical cross-hair, said primary horizontal cross-hair, said plurality of secondary horizontal cross-hairs, and said plurality of secondary vertical cross-hairs are provided by etching.

7. The method of claim 1, wherein said primary vertical cross-hair, said primary horizontal cross-hair, said plurality of secondary horizontal cross-hairs, and said plurality of secondary vertical cross-hairs are provided by printing.

8. The method of claim 1, wherein said primary vertical cross-hair, said primary horizontal cross-hair, said plurality of secondary horizontal cross-hairs, and said plurality of secondary vertical cross-hairs are provided by applying hairs or wires of known diameter.

9. The method of claim 1, further comprising the step of firing said cartridge at a target.

10. The method of claim 9, wherein said target is at a range greater than 500 yards.

11. The method of claim 10, wherein said target is at a range of 1000 yards to 2500 yards.

12. The method of claim 9, wherein said aiming point on said reticle projected by said ballistics calculator is superimposed on said target to track said target.

13. The method of claim 9, wherein said aiming point on said reticle projected by said ballistics calculator is aligned with a fixed point on said reticle wherein said ballistics calculator calculates an aiming solution for the position of said target in relation to a shooter at the moment of impact.

14. The method of claim 1, wherein said inputting further comprises inputting a reaction time of a shooter, and/or a lock time of a firearm.

15. The method of claim 12, wherein the travel of said target is tracked in three axes.

16. A method for using a computer running a ballistics program, comprising:

a) inputting cartridge, altitude, temperature and atmospheric pressure data into said computer running said ballistics computer program;

b) calculating points of impact on a target based on said data by said computer using said ballistics program;

c) selecting an aiming point on a reticle in a gunsight using said points of impact wherein said aiming point on said reticle is projected by said ballistics calculator.

17. The method of claim 16, wherein said aiming point on said reticle projected by said ballistics calculator is superimposed on said target to track said target.

18. The method of claim 17, wherein the travel of said target is tracked in three axes.

19. The method of claim 16, wherein said aiming point on said reticle projected by said ballistics calculator is aligned with a fixed point on said reticle wherein said ballistics calculator calculates an aiming solution for the position of said target in relation to a shooter at the moment of impact.

20. The method of claim 16, wherein said inputting further comprises inputting a reaction time of a shooter, and/or a lock time of a firearm.
