A recommendation that someone procure and read Brister's "Shotgunning, the Art and the Science" is the best thing to appear on this thread. It is available amazingly cheap, and is immensely entertaining and educational. Brister is a hero to the shotgunner, wrote of blood sports, including flyer shooting, in the mass media as well as the outdoor media, and was winning money with a shotgun in the last month of his long life.
