The document provides instructions for using Leupold tactical reticle systems, including the Mil Dot, Tactical Milling Reticle (TMR), Special Purpose Reticle (SPR), Close Mid-Range Reticle (CM-R2), Blackout Reticle, and CM-RW Reticle. It describes the components and subtensions of each reticle type, and how to use them to accurately estimate target range by matching the apparent size of the target in mils to lookup tables or formulas. The document also explains how to dial bullet drop corrections into a scope or hold over using the reticle markings.
