d) two or more mil lines of graduated length on said primary vertical cross-hair;

e) two or more offset mil lines subtending the gap between at least two mil lines on the primary horizontal cross-hair and the primary vertical cross hair to the left, to the right and above the intersection of the primary horizontal cross-hair and the primary vertical cross-hair wherein said two or more offset mil lines are offset in a V-shape;

f) two or more range markings along the primary vertical cross-hair below the intersection of the primary horizontal cross-hair and the primary vertical cross-hair;

g) two or more wind markings to the left and to the right of the primary vertical cross-hair below the intersection of the primary horizontal cross-hair and the primary vertical cross-hair;

h) two or more simultaneously visible secondary horizontal cross-hairs at predetermined distances on said primary vertical cross-hair; and

i) two or more simultaneously visible secondary vertical cross-hairs at predetermined distances on said simultaneously visible secondary horizontal cross-hairs, wherein an intersection of at least one of said two or more simultaneously visible secondary vertical cross-hairs and at least one of said two or more simultaneously visible straight line secondary horizontal cross-hairs provides an aiming point.

2. The reticle of claim 1, wherein said two or more mil lines of graduated length on said primary horizontal cross-hair and said two or more mil lines of graduated length on said primary vertical cross-hair are graduated in length in a replicated pattern.

3. The reticle of claim 1, wherein said two or more mil lines of graduated length on said primary horizontal cross-hair and said two or more mil lines of graduated length on said primary vertical cross-hair are successively 0.5 mils, 0.6 mils, 0.7 mils. 0.8 mils and 0.9 mils in length and wherein this pattern is replicated thereafter along said primary horizontal cross-hair and said primary vertical cross-hair.

4. The reticle of claim 1, wherein said two or more offset mil lines subtending the gap between at least two mil lines on the primary horizontal cross-hair and the primary vertical cross hair to the left, to the right and above the intersection of the primary horizontal cross-hair and the primary vertical cross-hair are successively spaced at 3.5, 3.6, 3.7, 3.8 and 3.9 mils.

5. The reticle of claim 1, wherein said two or more range markings along the primary vertical cross-hair below the intersection of the primary horizontal cross-hair and the primary vertical cross-hair comprise a gap.

6. The reticle of claim 5, wherein said gap corresponds to a predetermined dimension of a target at a predetermined range.

7. The reticle of claim 1, wherein said two or more range markings along the primary vertical cross-hair below the intersection of the primary horizontal cross-hair and the primary vertical cross-hair comprise an oval.

8. The reticle of claim 7, wherein the longest diameter of said oval corresponds to a predetermined dimension of a target at a predetermined range.

9. The reticle of claim 1, wherein said two or more wind markings to the left and to the right of the primary vertical cross-hair below the intersection of the primary horizontal cross-hair and the primary vertical cross-hair are selected from a group consisting of a dot, a cross, an uninterrupted line, an interrupted line, a number and a line comprising two or more numbers.

10. The reticle of claim 1, wherein said two or more wind markings to the left and to the right of the primary vertical cross-hair below the intersection of the primary horizontal cross-hair and the primary vertical cross-hair are calibrated for the velocity of a target, properties of a projectile, properties of a firearm, or properties of the environment.

11. The reticle of claim 10, wherein said properties of the environment comprise density altitude, wind speed, wind direction, and wind angle.

12. The reticle of claim 1 further comprising velocity of a target markings above or below said primary horizontal cross-hair.

13. The reticle of claim 1, wherein said primary horizontal cross-hair is a line.

14. The reticle of claim 13, wherein said primary horizontal cross-hair line is a straight line.

15. The reticle of claim 14, wherein said straight line is an uninterrupted straight line.

16. The reticle of claim 1, wherein said primary horizontal cross-hair has a predetermined thickness.

17. The reticle of claim 16, wherein said predetermined thickness is a single thickness along said primary horizontal cross-hair.

18. The reticle of claim 1, wherein said primary vertical cross-hair is a line.

19. The reticle of claim 18, wherein said primary vertical cross-hair line is a straight line.

20. The reticle of claim 19, wherein said straight line is an uninterrupted straight line.

21. The reticle of claim 1, wherein said primary vertical cross-hair has a predetermined thickness.

22. The reticle of claim 21, wherein said predetermined thickness is a single thickness along said primary vertical cross-hair.

23. The reticle of claim 1, wherein said primary horizontal cross-hair and said primary vertical cross-hair physically cross at an intersection point.
