Historical Notes: Swiss military cartridge adopted in 1869 for use in the Vetterli turnbolt rifle. The official military round is rim-fire, but a center-fire version was also loaded in Europe. The cartridge and rifle were discontinued in 1889.
The 10.4mm, or 41 Swiss, cartridge is quite well known in the U.S. and most american companies loaded it until about 1942. Thousands of the Swiss Vetterli rifles have been sold in this country and a surprising number have been used for hunting big game, usually deer. The 41 Swiss would be a barely adequate, short-range, cartridge for deer-class animals. The rim-fire military version can't be reloaded.
This model was also adopted by the Italians, with the same ballistics. It was modified with a tube magazine at first, then to a box magazine. The Italian version was known as the Vitali system.
