The 16 gauge is one of only two gauges with a natural "square load"; that is the length of the shot load is the same as the width of the barrel. This state of affairs promotes short shot columns and even patterns. This allows the smaller, lighter 16 gauge to compete with the 12 gauge for effectiveness in the field. While best suited to fast flushing game, the 16 gauge can be used effectively for waterfowl and even with slugs. The 16 is regaining popularity among wingshooters and more ammo is available now than 20 years ago. It has always been viewed favourably in continental Europe.
There is something very right with a well designed, well balanced scaled-for-the-gauge 16 bore shotgun, whether it is an American SxS such as an A. H. Fox, a German U/O like a Merkel, or even a pump gun such as the Winchester 1897. A 6 lb. 16 gauge throwing one ounce of shot has very workable, user friendly proportions.
