This logbook is designed to log in sight zeros for various rifles, ranges, yardages, and loads. It is extremely important to record sight zeros so you can quickly get on target the next time you shoot. The logbook has a stiff cover with 40 single-side printed pages (no bleedthrough) providing space for 160 sight settings. You can record the rifle used, sights used, range location, range altitude, yardage line, rear sight elevation and windage, front sight elevation and iris setting, and the load used.
