Robert Petersen, the founder of Petersen Publishing, started with mimeographed newsletters and turned them into a massive publishing empire, including Motor Trend, Guns & Ammo and Petersen’s Hunting. An avid hunter and gun collector, Petersen also served as commissioner for the shooting sports during the Los Angeles Olympics. Thanks to a gift from his late wife, Margie Petersen, the National Firearms Museum has a new wing called the Petersen Gallery housing hundreds of the world's most exquisite firearms. The straight-pull R8 is the latest beefed-up rendition of the innovative Blaser rifle, and Shooting Editor Glenn Gilbert evaluates the transformative Blaser. The rare wooden-stocked German MP41 is unusual in that its old school design was outdated by the MP40—which was adopted before the MP41 was even on the drawing board.
