The document provides instructions for using a Sightron riflescope with a Hunter Holdover Reticle (HHR) for shooting out to 400 yards. It explains that the reticle is designed to simplify long range shooting through holdover points. It then gives steps for selecting an appropriate bullet load, zeroing the scope at 200 yards, and using the reticle's correction values to accurately hit targets at further distances by compensating for bullet drop through the holdover points.
