This document provides specifications and instructions for using an illuminated reticle including the width and height of different mil and sub-mil bars, the diameter of the center dot, and the spacing between mil markings. It explains how to calculate target range by dividing the target's height or width in meters by the number of mils it subtends on the reticle. Additionally, it provides information about how first focal plane reticles change in size to maintain consistent subtensions at different magnifications and can be used for holdovers by matching bullet drop to reticle subtensions.

Data Valid for SVIIISSED540X56FFPZSIRLRM Only
Mil based reticles allow you to range targets to determine distance. To determine the range of your
target divide the height or width of the target in Meters x(1000) divided by the Mils on the reticle.
About First Focal Plane Reticles
In First Focal Plane scopes the Reticle Subtension remains the same throughout all magnifications.
First Focal Plane reticles change in size to maintain a consistent subtension to the field of view.
First Focal Plane reticles can be used for ballistic holdover by matching the bullet drop of the load being used
by the subtension on the reticle.
