Abstract

A reticle for a projectile weapon aiming device, such as a riflescope, includes a primary horizontal sight line that intersects a primary vertical sight line to define a primary aiming point. A circle is centered on the primary aiming point to intersect the primary horizontal and vertical sight lines. Multiple aiming marks are preferably spaced apart along the primary horizontal and vertical sight lines and cooperate with the circle and the sight lines to form horizontal and vertical scales for estimating a range to a target having features of known or estimable size. The scales also facilitate windage and holdover aiming adjustments. The circle may facilitate quick target acquisition in rapid fire engagements, as well as enhance range estimation capabilities.

Claims

1. A reticle for a projectile weapon aiming system, comprising:

a primary horizontal sight line;

a primary vertical sight line intersecting the primary horizontal sight line to define a primary aiming point;

a circle centered on the primary aiming point, the circle intersecting the primary horizontal sight line to the right and left of the primary aiming point, and the circle intersecting the primary vertical sight line below the primary aiming point;

multiple horizontal aiming marks spaced apart along the primary horizontal sight line, the horizontal aiming marks, the intersections of the circle with the primary horizontal sight line, and the primary vertical sight line cooperating to form a horizontal scale for estimating a range to a target having features of known or estimable horizontal size, the horizontal aiming marks and the circle also being usable as aiming points for windage adjustment and leading of a moving target; and

multiple vertical aiming marks spaced apart along the primary vertical sight line, the vertical aiming marks, the intersections of the circle with the vertical sight line, and the primary horizontal sight line cooperating to form a vertical scale for estimating range to a target having features of known or estimable vertical size, the vertical aiming marks and the circle also being usable as aiming points for holdover adjustment at predetermined ranges.

2. The reticle of claim 1, wherein the diameter of the circle subtends 10 mils.

3. The reticle of claim 1, wherein the vertical and horizontal scales are divided in increments of 5 mils.

4. The reticle of claim 1, wherein the vertical and horizontal scales are divided in increments of 2.5 mils.

5. The reticle of claim 1, wherein the primary aiming point comprises a dot.

6. The reticle of claim 5, wherein the dot subtends 0.3 mils.

7. The reticle of claim 1, wherein:

the vertical aiming marks include secondary vertical aiming marks and tertiary vertical aiming marks that are smaller than the secondary vertical aiming marks; and

the horizontal aiming marks include secondary horizontal aiming marks and tertiary horizontal aiming marks that are smaller than the secondary horizontal aiming marks.

8. The reticle of claim 1, wherein at least one of the vertical aiming marks and at least two of the horizontal aiming marks is located inside the circle.

9. The reticle of claim 1, wherein one of the vertical aiming marks bisects a segment of the primary vertical sight line extending between the primary aiming point and the intersection of the circle with the primary vertical sight line.

10. The reticle of claim 1, wherein the horizontal aiming marks include marks that bisect a segment of the primary horizontal sight line extending between the primary aiming point and the intersection of the circle with the primary horizontal sight line to the right and left of the primary aiming mark.

11. The reticle of claim 1, wherein:

the primary horizontal sight line includes

a horizontal central portion extending radially from the primary aiming point, and

a horizontal post portion being at least one and a half times thicker than the horizontal central portion and extending radially from the horizontal central portion; and

the primary vertical sight line includes

a vertical lower central portion extending radially from the primary aiming point, and

a vertical post portion being at least one and a half times thicker than the vertical central portion and extending radially from the vertical lower central portion.

12. A projectile weapon aiming system including the reticle of claim 1.

13. A riflescope including the reticle of claim 1.
