1. A method for using a ballistics calculator to generate aiming information, said ballistics calculator comprising a processor, a display screen, and a ballistics computer program on a computer readable medium, said method comprising:

  • a) inputting information into said ballistics calculator regarding a target acquisition device, said target acquisition device comprising a reticle, said reticle comprising;

    i) a primary horizontal cross-hair;

    ii) a primary vertical cross-hair that intersects said primary horizontal cross-hair;

    iii) two or more vertical lead markings upon said primary horizontal cross-hair;

    iv) two or more horizontal line rangefinder markings above said vertical lead markings to the left of said primary vertical cross-hair and two or more horizontal line rangefinder markings above said vertical lead markings to the right of said primary vertical cross-hair;

    v) two or more evenly spaced simultaneously visible straight line secondary horizontal cross-hairs on said primary vertical cross-hair below said primary horizontal cross-hair; and

    vi) two or more simultaneously visible straight line secondary vertical cross-hairs on said simultaneously visible straight line secondary horizontal cross-hairs below said primary horizontal cross-hair, wherein an intersection of at least one of said two or more simultaneously visible straight line secondary vertical cross-hairs and at least one of said two or more simultaneously visible straight line secondary horizontal cross-hairs provides an aiming point;

    b) inputting information into said ballistics calculator regarding one or more of;

    i) external conditions;

    ii) a projectile;

    iii) a relation of a shooter and a target; and

    iv) a ballistics drag model and ballistic coefficient;

    c) calculating aiming information from said information regarding the target acquisition device and said information regarding one or more of external conditions, a projectile, a relation of a shooter and a target, and a ballistics drag model and ballistic coefficient by running said ballistics computer program on said processor; and

    d) displaying said aiming information on said display.
