There seems to be quite a few new shooters in the house, so I would like to recommend a great little book. It was written by the late, great Jack O'Connor and titled Rifle and Shotgun Shooting Basics. Published by Outdoor Life it is all of 40 pages thick and is replete with drawings, diagrams, and pretty pictures. Mine is from the Third Printing, 1986. If you can find it, you'll want to have it. Jack himself graces the cover.
