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) an optical center; and
b) two or more slanted non-perpendicular wind lines evenly spaced to the left and to the right of said optical center wherein one or more of said two or more slanted non-perpendicular wind lines 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 two or more slanted non-perpendicular wind lines 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 two or more slanted non-perpendicular wind lines 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 a first horizontal line and a first vertical line that intersect at said optical center.
5. The reticle of claim 4 , wherein said first horizontal line and said first vertical line physically cross at an intersection point.
6. The reticle of claim 4 , wherein an intersection of said first horizontal line and said first vertical line comprises a gap and a dot.
7. The reticle of claim 4 , further comprising rangefinder markings.
8. The reticle of claim 7 , wherein said rangefinder markings comprise one or more horizontal line rangefinder markings that intersect said first vertical line at a position above said first horizontal line.
9. The reticle of claim 1 , further comprising at least one circumscribing ring centered on said optical center.
10. The reticle of claim 1 , wherein one or more of said two or more slanted non-perpendicular wind lines is a dashed line.
11. The reticle of claim 1 , wherein one or more of said two or more slanted non-perpendicular wind lines is a straight line.
12. The reticle of claim 1 , wherein said two or more slanted non-perpendicular wind lines comprises four slanted non-perpendicular wind lines.
13. The reticle of claim 1 , wherein said two or more slanted non-perpendicular wind lines are below said optical center.
14. The reticle of claim 1 , wherein said optical center coincides with a center of a field of vision when said reticle is mounted in a scope.
