1. A method for using a computer running a ballistics program, comprising:
a) inputting cartridge, altitude, temperature and atmospheric pressure data into said computer running said ballistics computer program; b) calculating points of impact based on said data by said computer using said ballistics program; c) selecting an aiming point on a reticle in a gunsight using said points of impact wherein said reticle comprises:
1) a primary vertical cross-hair;2) a primary horizontal cross-hair intersecting said primary vertical cross-hair;3) a plurality of secondary horizontal cross-hairs evenly spaced along said primary vertical cross-hair; and4) a plurality of secondary vertical cross-hairs evenly spaced along at least some of said secondary horizontal cross-hair wherein said secondary vertical cross-hairs intersect one and only one secondary horizontal cross-hair.
