Shooting calibration systems and methods
The present invention relates to target acquisition and related systems and 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. The present invention also provides targets and methods of using the systems to achieve enhanced shooting accuracy.
1. A target for shooting calibration, comprising markings configured to assess: 1) initial zeroing of a firearm; 2) accuracy of a plurality of elevation adjustments at a predetermined distance from the shooter; and 3) markings configured to assess cant.
2. The target of claim 1 , wherein said markings comprise primary vertical and horizontal lines intersecting on the target, and a plurality of secondary horizontal lines at defined unit increments above and below the primary horizontal lines, said increments defined by said elevation adjustments.
3. The target of claim 2 , wherein said markings further comprise numerical unit measurements labeling said secondary horizontal lines.
4. The target of claim 2 , further comprising a plurality of secondary vertical lines intersecting with said secondary horizontal lines.
5. The target of claim 4 , wherein said secondary vertical lines are at defined unit increments to the left and right of the primary vertical line, said increments defined by windage adjustments.
6. The target of claim 2 , further comprising one or more markings that define a bull's-eye.
7. The target of claim 6 , wherein at least one of said bull's-eye markings is at the intersection of said primary horizontal and vertical lines.
8. The target of claim 6 , wherein at least one of said bull's-eye markings comprises a circular shape.
9. The target of claim 8 , wherein said circular shape comprises two or more concentric circles.
10. The target of claim 6 , wherein a plurality of said bull's-eye markings are positioned at predefined distances along said secondary horizontal lines.
11. The target of claim 1 , wherein said predetermined distance is 100 yards or 100 meters.
12. A target for shooting calibration, comprising two or more zones, each of said two or more zones having markings configured to assess accuracy of a plurality of elevation adjustments of a target acquisition device, at a single predetermined distance from the shooter, and markings configured to assess cant.
13. The target of claim 12 , wherein said two or more zones comprises three zones.
14. The target of claim 12 , wherein each of said zones comprises a primary horizontal and vertical line and a plurality of secondary horizontal lines above said primary horizontal lines, said secondary horizontal lines positioned at defined unit increments, said increments defined by said elevation adjustments.
15. The target of claim 1 or claim 12 , wherein said target has an external shape that is not square or rectangular.
16. The target of claim 15 , wherein said external shape comprises a plurality of edges that are not parallel or perpendicular with any other edge.
17. A target for shooting calibration, comprising markings configured to assess: 1) initial zeroing of a firearm; 2) accuracy of a plurality of elevation adjustments at a predetermined distance from the shooter; and 3) one or more markings that define a bull's-eye wherein said markings comprise primary vertical and horizontal lines intersecting on the target, and a plurality of secondary horizontal lines at defined unit increments above and below the primary horizontal lines said increments defined by said elevation adjustments, and wherein a plurality of said bull's-eye markings are positioned at predefined distances along said secondary horizontal lines.
18. The target of claim 17 , wherein said markings further comprise numerical unit measurements labeling said secondary horizontal lines.
19. The target of claim 17 , further comprising a plurality of secondary vertical lines intersecting with said secondary horizontal lines.
20. The target of claim 19 , wherein said secondary vertical lines are at defined unit increments to the left and right of the primary vertical line, said increments defined by windage adjustments.
21. The target of claim 17 , wherein said predetermined distance is 100 yards or 100 meters.
22. The target of claim 17 , wherein at least one of said bull's-eye markings is at the intersection of said primary horizontal and vertical lines.
23. The target of claim 17 , wherein at least one of said bull's-eye markings comprises a circular shape.
24. The target of claim 23 , wherein said circular shape comprises two or more concentric circles.
25. The target of claim 17 , wherein a plurality of said bull's-eye markings are positioned at predefined distances along said secondary horizontal lines.
26. The target of claim 17 , wherein said target has an external shape that is not square or rectangular.
27. The target of claim 26 , wherein said external shape comprises a plurality of edges that are not parallel or perpendicular with any other edge.
