It makes as much sense as calling the 270 WSM a short magnum. The nomenclature suggests there should be a long one. At least with the 300 WSM there is a Winchester longer mag, and, while the 7mm doesn't have a Winchester long partner in the line-up, it probably can get a pass since the Rem Mag version is often simply called the "Seven Mag". But what's up with calling the 350 Remington a Magnum? The only thing magnum there is the belt. Since that is the case, simply saying 350 Remington belted would suffice. And "38" for a cartridge that uses bullets not even 36 caliber? Give me a break!
Actually, I don't sweat the names of cartridges. On the contrary, when things seem off somehow, usually there's a clue that a story of some kind exists, and that's never a bad thing if you like history.
