.300 win mag is actually exactly the same caliber, 0.308 inches.  Its just common practice to not name new rounds by their exact caliber when it might cause confusion.  The same thing with .357 magnum and .38 special.  They are the same caliber, 0.357, but if they called it .357 special then people might buy .357 magnum ammo accidentally only to find out it doesn't fit in the gun (or worse, with some rounds you can confuse it with the wrong ammo that does still fit but blows up the gun).
