Abstract
An improved telescopic gunsight is provided by combining a conventional telescopic gunsight with a reticle having a primary vertical cross-hair, a primary horizontal cross-hair intersecting the primary vertical cross-hair, a plurality of secondary horizontal cross-hairs having predetermined thickness evenly spaced a predetermined distance along the primary vertical cross-hair, a plurality of secondary vertical cross-hairs having predetermined thickness evenly spaced a predetermined distance along at least some of the secondary horizontal cross-hairs and an optical range-finder for quickly determining the range to the intended target. Some of the secondary horizontal cross-hairs are marked with a unique identifying character to assist the shooter in quickly finding an aiming point. The thickness of, and spacing between, the cross-hairs can be based upon an easy to learn inches of angle (or centimeters of angle) scale, or upon any other conventional scale, which can be the same or different from the scale used for the rangefinder. The rangefinder can be formed from vertical and horizontal arms. The vertical rangefinder arm can be superimposed over the primary vertical cross-hair and …
