Quick ranging with silhouettes
To use the reticle, simply match the
person or object being ranged to the
silhouette that is closest in shape and read
the indicated yardage. Note: The best
accuracy will be obtained by bracing the
arms or using a tripod mount.
Examples
Using silhouette widths—The silhouettes used in the R/T reticle are based on
an average 20-inch shoulder width and 11-inch head width. Take your range
reading from the silhouette that most closely matches the size of the person.
Using silhouette heights—Heights of the silhouette may also be used to
quickly estimate range when comparing objects of known dimensions. For
example, assuming a typical back-to-brisket dimension of 17 inches, a deer can
be ranged using the 17-inch shoulder height on any of the silhouettes.
