The .25-20 Single-Shot was designed by J. Francis Rabbeth and was introduced around 1882. This case was used in single-shot rifles and was one of the first center-fire cases developed. The .25-20 SS became obsolete around the 1930s. It is a very accurate round and is great for hunting varmints and small game.
