Sample text

Nevertheless, there's no question that the self-loader is in some ways the ultimate repeater, nor that Browning's venerable A-5 squareback gun, described in a series of patents first issued in October 1900, affected the shooting world like the movement of tectonic plates. Browning used recoil energy to make his autoloader work, and so did everyone else for the next fifty years. Some systems were decidedly better than others, but they were all based on recoil. The next milestone came when someone decided to use gas energy instead.

29 THE H ON O R ROLL Ever wonder how your gun got to be the way it is? W hy its mechanics work one way rather than another? Whose idea was what, and when? The history of the gun is a chronicle of evolution. By the same token, it also is a history studded with endpoints-mechanical systems brought to such a level of perfection that they subsequently became the standards of their kind, and became in turn the milestones of their particular evolution­ ary branches. Many such things mark the development of the gun; the flintlock, the caplock, certainly the breechloader and the self-contained cartridge all qual­ ify as inventions that helped shape evolution.

410 for every game up to and including turkeys, and if I had a dollar for every time some fool has blithely pronounced it perfect for a beginning shooter, I could buy one of McKay Brown's round-actions and have some cash left over. 41O is, in fact, the worst gun you could possibly give a beginner, way too difficult to shoot well and the antithesis of the confidence-building a beginner needs. 410 can be a hoot-provided you're philosophical enough to accept the fact that you can do everything right and still see targets sail off unscathed or merely nicked.
