The document summarizes the features and use of the Vortex EBR-3 mrad reticle, including: - The reticle is etched on glass and uses mrad (milliradian) measurements for ranging, holdovers, windage corrections, and moving target leads. - Mrads provide a finer scale than MOA (minute of angle) and are simpler to use for long distance shooting calculations. - The reticle includes markings in .1 and .5 mrad increments to aid in ranging and ballistic calculations using distance, target size, and mrad measurements. - Shooters can use the reticle markings and their knowledge of bullet ballistics in mrads to quickly estimate
