Rifle sight analog template

A method of using an analog calculator for long range shooting, comprising the steps of:

• (a) using a stationary, flat, rectangular rule member comprising:
• an axial center, a front face, and a rear face;
• said front face having an outer, circular face scale with a target indicia and an inner angle/cosine scale and angle fire protractor;
• a rotatable, transparent disc mounted on said front face having an outer front disc scale adjacent said outer, circular face scale, and an inner front disc scale spaced from said outer front disk scale adjacent said inner angle/cosine scale, wherein said outer, circular face scale and said outer front disc scale are configured for multiplication and division and computing distance to a target, by aligning a target size located on said outer front disc scale with said target indicia located on said outer, circular face scale;
• said rear face having a rear face sum scale in an outer ring of numbers, a rear face direction scale ranging from zero to 12 o'clock inner and spaced from said outer ring of numbers, a rear face target bloc inner to said direction scale, and rear face annular arrays of inner, blank cosine cells;
• large and small transparent discs, independently and rotatably mounted on said rear face;
• wherein said large disc having an addition and subtraction scale in a disc outer section thereof adjacent to said rear face sum scale, and ½ and ⅓ scales on a disc inner section spaced from said disc outer section configured for quick division needed for windage adjustment equations and interpolation;
• and
• wherein said small disc is rotatably mounted over said large disc and comprises a full value ring surrounding wind speed values, and overlaps and surrounds said rear face annular arrays of inner, blank cosine cells;
• (b) calculating a target range by using said disc on said front face to perform necessary multiplication and division steps.
