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 reticle, comprising:
a) a first horizontal cross-hair;
b) a first vertical cross-hair that intersects said first horizontal cross-hair;
c) two or more evenly spaced horizontal cross-hairs on said first vertical cross-hair below said first horizontal cross-hair;
d) two or more vertical cross-hairs on said evenly spaced horizontal cross hairs on said first vertical cross-hair below said first horizontal cross-hair; and
e) one or more slanted non-perpendicular wind lines that intersect at least one of said two or more evenly spaced horizontal cross-hairs wherein one or more of said one or more slanted non-perpendicular wind lines that intersect said at least one of two or more evenly spaced horizontal cross-hairs is ballistically calculated to match a projectile's performance when air motion and/or target movement is a factor that affects a flight of a projectile and a point of impact down range.
2. The reticle of claim 1 , wherein one or more of said one or more slanted non-perpendicular wind lines that intersect said at least one of two or more evenly spaced horizontal cross-hairs is ballistically calculated to match an intercept point of said projectile's performance when said target movement is 4 mph.
3. The reticle of claim 1 , wherein one or more of said one or more slanted non-perpendicular wind lines that intersect said at least one of two or more evenly spaced horizontal cross-hairs is ballistically calculated to provide a user with a windage hold when said air motion is a factor that affects said flight of said projectile and said point of impact down range.
4. The reticle of claim 1 , further comprising rangefinder markings.
5. The reticle of claim 4 , wherein said rangefinder markings comprise one or more horizontal line rangefinder markings that intersect said first vertical cross-hair at a position above said first horizontal cross-hair.
6. The reticle of claim 1 , wherein said first horizontal cross-hair and said first vertical cross-hair physically cross at an intersection point.
7. The reticle of claim 1 , wherein at least one of said two or more horizontal cross-hairs on said first vertical cross-hair below said first horizontal cross-hair is shorter in length than said first horizontal cross-hair.
8. The reticle of claim 1 , wherein a plurality of said two or more vertical cross-hairs on said evenly spaced horizontal cross hairs on said first vertical cross-hair below said first horizontal cross-hair are evenly spaced.
9. The reticle of claim 1 , wherein at least one of said two or more vertical cross-hairs on said evenly spaced horizontal cross hairs on said first vertical cross-hair below said first horizontal cross-hair is a dot.
10. The reticle of claim 1 , further comprising a zero aiming point at the intersection of said first vertical cross-hair and said first horizontal cross-hair.
11. The reticle of claim 1 , further comprising at least one straight line horizontal cross-hair on said first vertical cross-hair above said first horizontal cross-hair.
12. The reticle of claim 1 , wherein the intersection of said first horizontal cross-hair and said first vertical cross-hair comprises a gap and a dot.
13. The reticle of claim 1 , further comprising two or more wind dots to the left and two or more wind dots to the right of two or more of said two or more evenly spaced horizontal cross-hairs on said first vertical cross-hair below said first horizontal cross-hair.
14. The reticle of claim 1 , wherein an intersection of at least one of said two or more vertical cross-hairs on said evenly spaced horizontal cross hairs on said first vertical cross-hair below said first horizontal cross-hair and at least one of said two or more evenly spaced horizontal cross-hairs on said first vertical cross-hair below said first horizontal cross-hair provides an aiming point.
15. The reticle of claim 1 , further comprising at least one circumscribing ring centered on the intersection point of said first horizontal cross-hair and said first vertical cross-hair.
16. The reticle of claim 15 , wherein said ring is a continuous ring.
17. The reticle of claim 15 , wherein said ring is an interrupted ring.
18. The reticle of claim 15 , wherein said at least one circumscribing ring centered on said intersection point of said first horizontal cross-hair and said first vertical cross-hair intersects one or more of said one or more slanted non-perpendicular wind lines that intersect said at least one of said two or more evenly spaced horizontal cross-hairs.
19. The reticle of claim 15 , wherein said at least one circumscribing ring is two or more circumscribing rings.
20. The reticle of claim 15 , wherein said reticle comprises a substantially transparent disc having an optical center and an edge for mounting said disc, and said circumscribing ring is positioned optically between said optical center and said edge, said ring spaced from said edge and circumscribing said optical center and one or more aiming points.
21. The reticle of claim 1 , wherein one or more of said one or more slanted non-perpendicular wind lines is a dashed line.
22. The reticle of claim 1 , wherein one or more of said one or more slanted non-perpendicular wind lines is a straight line.
23. The reticle of claim 1 , wherein one or more of said one or more slanted non-perpendicular wind lines is a curved line.
24. A reticle, comprising: a) a first horizontal cross-hair; b) a first vertical cross-hair that intersects said first horizontal cross-hair; c) two or more evenly spaced horizontal cross-hairs on said first vertical cross-hair below said first horizontal cross-hair; d) two or more vertical cross-hairs on said evenly spaced horizontal cross hairs on said first vertical cross-hair below said first horizontal cross-hair; and e) one or more slanted non-perpendicular wind lines that intersect at least one of said two or more evenly spaced horizontal cross-hairs, wherein one or more of said one or more slanted non-perpendicular wind lines is an interrupted line.
25. The reticle of claim 24 , wherein said interrupted line comprises one or more dots.
