Apparatus and method for calculating aiming point information
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.
1. A firearm reticle, comprising:
a) a primary horizontal cross-hair;
b) a primary vertical cross-hair that intersects said primary horizontal cross-hair;
c) two or more aiming points on said primary vertical cross-hair above said primary horizontal cross-hair;
d) two or more secondary horizontal cross-hairs on said primary vertical cross-hair above said primary horizontal cross-hair;
e) two or more wind dots to the left and two or more wind dots to the right of said two or more secondary horizontal cross-hairs on said primary vertical cross-hair above said primary horizontal cross-hair;
f) at least one secondary horizontal cross hair at the uppermost end of said primary vertical cross-hair;
g) two or more vertical lead markings upon said primary horizontal cross-hair;
h) two or more horizontal rangefinder markings above said vertical lead markings;
i) two or more evenly spaced simultaneously visible straight line secondary horizontal cross-hairs on said primary vertical cross-hair below said primary horizontal cross-hair; and
j) two or more simultaneously visible straight line secondary vertical cross-hairs on said simultaneously visible straight line secondary horizontal cross-hairs below said primary horizontal cross-hair, wherein an intersection of at least one of said two or more simultaneously visible straight line 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 primary horizontal cross-hair is a line.
3. The reticle of claim 1 , wherein said line is a straight line.
4. The reticle of claim 3 , wherein said straight line is an uninterrupted straight line.
5. The reticle of claim 1 , wherein said primary horizontal cross-hair has a predetermined thickness.
6. The reticle of claim 5 , wherein said predetermined thickness is a single thickness along said primary horizontal cross-hair.
7. The reticle of claim 1 , wherein said primary vertical cross-hair is a line.
8. The reticle of claim 7 , wherein said line is a straight line.
9. The reticle of claim 8 , wherein said straight line is an uninterrupted straight line.
10. The reticle of claim 1 , wherein said primary vertical cross-hair has a predetermined thickness.
11. The reticle of claim 10 , wherein said predetermined thickness is a single thickness along said primary vertical cross-hair.
12. The reticle of claim 1 , wherein said primary horizontal cross-hair and said primary vertical cross-hair physically cross at an intersection point.
13. The reticle of claim 1 , wherein at least one of said two or more secondary horizontal cross-hairs is an uninterrupted straight line.
14. The reticle of claim 1 , wherein at least one of said two or more secondary horizontal cross-hairs is a predetermined thickness.
15. The reticle of claim 14 , wherein said predetermined thickness is a single thickness along said at least one of said two or more secondary horizontal cross-hairs.
16. The reticle of claim 1 , wherein at least one of said two or more secondary horizontal cross-hairs is shorter in length than said primary horizontal cross-hair.
17. The reticle of claim 1 , wherein at least one of said two or more secondary vertical cross-hairs is an uninterrupted straight line.
18. The reticle of claim 1 , wherein at least one of said two or more secondary vertical cross-hairs is a predetermined thickness.
19. The reticle of claim 18 , wherein said predetermined thickness is single thickness along said at least one of said two or more secondary vertical cross-hairs.
20. The reticle of claim 1 , wherein at least one of said two or more secondary vertical cross-hairs is shorter in length than the primary vertical cross-hair.
21. The reticle of claim 1 , wherein a plurality of said two or more secondary vertical cross-hairs are evenly spaced.
22. The reticle of claim 1 , wherein said two or more vertical lead markings are evenly spaced.
23. The reticle of claim 1 , wherein said two or more horizontal rangefinder markings are unevenly spaced above said two or more vertical lead markings.
24. The reticle of claim 1 , wherein said two or more vertical lead markings upon said primary horizontal cross-hair are identified by numbers.
25. The reticle of claim 1 , further comprising a zero aiming point at the intersection of said primary vertical cross-hair and said primary horizontal cross-hair.
26. The reticle of claim 1 , further comprising a zero aiming point at the intersection of said primary vertical cross hair and said at least one secondary horizontal cross hair at the uppermost end of said primary vertical cross-hair.
27. The reticle of claim 1 , wherein said two or more aiming points on said primary vertical cross-hair above said primary horizontal cross-hair are unevenly spaced.
28. The reticle of claim 1 , wherein said two or more secondary horizontal cross-hairs on said primary vertical cross-hair above said primary horizontal cross-hair are evenly spaced.
29. The reticle of claim 1 , wherein said two or more aiming points on said primary vertical cross-hair above said primary horizontal cross-hair alternate with said two or more secondary horizontal cross-hairs on said primary vertical cross-hair above said primary horizontal cross-hair on said primary vertical cross-hair.
30. The reticle of claim 1 , wherein said two or more aiming points on said primary vertical cross-hair above said primary horizontal cross-hair are identified by numbers.
31. The reticle of claim 1 , wherein said wind dots are unevenly spaced.
32. The reticle of claim 1 , wherein said two or more evenly spaced simultaneously visible straight line secondary horizontal cross-hairs on said primary vertical cross-hair below said primary horizontal cross-hair are identified by numbers.
33. The reticle of claim 32 , wherein said two or more evenly spaced simultaneously visible straight line secondary horizontal cross-hairs on said primary vertical cross-hair below said primary horizontal cross-hair are identified by different numbers to the left and to the right of said primary vertical cross-hair.
