I understand the reasons why this cartridge was originally designed. But I can't begin to understand why the round took the form that it did. It's called the 5.5 mm Velo Dog and it was designed in France before the 19th Century rolled over into the 20th. Imagine a straight-sided revolver cartridge case about the length of a .38 Spl., with a typical, but rather wide rim. The bullet was a .22, actually measuring about .225 inches in diameter and weighing (I think) about 30 to 35 grains. Fired from several brands of compact French, Belgian or German revolvers, the 5.5 mm Velo Dog delivered performance much like a rimfire .22 Long (not Long Rifle). Bicyclists of that Victorian era were apparently so troubled by pursuing dogs that this cartridge and the guns that fired it were the result. They just couldn't forgive Woofy and his canine indiscretions. And that's where the name came from: “Velo” is an abbreviated form of the French word for bicycle, so it is literally “bicyclist's dog gun.” In view of the annual billions of dollars currently spent on dogs, dog food and dog care, it's hard to envision a time when we deliberately produced a specialized gun/cartridge combo with which to shoot them. But it happened.
