Abstract

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.

Claims

1. A method for shooting calibration, comprising:

a.) providing a target comprising markings configured to assess;

i.) initial zeroing of a firearm;

ii.) accuracy of a plurality of elevation adjustments at a predetermined distance from the shooter; and

iii.) markings configured to assess cant; and

b.) shooting at said target with a firearm.

2. The method of claim 1, wherein a plurality of shots are taken.

3. The method of claim 2, wherein at least one of said plurality of shots is taken to assess zero position.

4. The method of claim 2, wherein at least two of said plurality of shots are taken with different elevation adjustments.

5. The method of claim 2, wherein at least two of said plurality of shots are taken with different windage adjustments.

6. The method of claim 2, wherein said plurality of shots comprises a series of shots of increasing elevation adjustments, followed by a series of shots of decreasing elevation adjustments.

7. The method of claim 2, wherein cant is validated after said shots are taken.

8. The method of claim 2, wherein results of said shots are recorded.

9. The method of claim 8, wherein information about said firearm or shooter is further recorded.

10. The method of claim 1, wherein said target is placed at said predefined range from a shooter at a target range.

11. The method of claim 10, wherein said target range employs a plurality of said targets.

14. The method of claim 1, claim 12 or claim 13, wherein said target has an external shape that is not square or rectangular.

15. The method of claim 14, wherein said external shape comprises a plurality of edges that are not parallel or perpendicular with any other edge.

12. A method for shooting calibration, comprising:

a.) providing a target, comprising;

i.) 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

ii.) markings configured to assess cant; and

b.) shooting at said target with a firearm.

13. A method for shooting calibration, comprising:

a.) providing a target comprising markings configured to assess;

i.) initial zeroing of a firearm;

ii.) accuracy of a plurality of elevation adjustments at a predetermined distance from the shooter; and

iii.) one or more markings that define a bull'"'"'s-eye wherein said markings comprise primary vertical and horizontal lines intersecting on said target, and a plurality of secondary horizontal lines at defined unit increments above and below said 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; and

b.) shooting at said target with a firearm.

16. A set of targets comprising two or more targets comprising markings configured to assess:

a.) initial zeroing of a firearm;

b.) accuracy of a plurality of elevation adjustments at a predetermined distance from the shooter; and

c.) markings configured to assess cant.

17. A shooting system, comprising:

a.) a target comprising markings configured to assess;

i.) initial zeroing of a firearm;

ii.) accuracy of a plurality of elevation adjustments at a predetermined distance from the shooter; and

iii.) markings configured to assess cant; and

b.) one or more shooting devices and components.

18. The system of claim 17, wherein said one or more shooting devices and components are selected from the group consisting of:

a riflescope, a reticle, a firearm, ballistics software, a spotting scope, a cant indicator, a computing device, a laser, night-vision equipment, and a device that measures or calculates an environment condition.
