This is our latest version of our sniper data logbook. It is made of #27 Paper Tyger, a thinner yet more durable paper that is tear and weather resistant. It has over 200 pages that contain blank data sheets for cold-bore, moving targets, zero, and unknown distance shooting. There are also sheets for range cards, sketches, and observation logs. Also included are data sections for wind deflection, weather effects, slope shooting, moving target leads, and others. This data book is very complete and easy to use. It has a nice spiral binding that allows for easy use by flipping the pages all the way over. The dimensions of the pages are 8.5″x5.5″. Including the coil binding the exterior dimensions of the book are 9.0″x5.5″.
