While the 6.5 uses the 300RCM parent case, and utilizes a magnum bolt face, it's not really been considered, or identified as a magnum....No more then the 6.5x284N is considered a magnum with its near identical case capacity and performance. Usable case capacities of both(along with a few other wildcats)fall in this 30-06 capacity region, but using short/fat dimensions. I think the likes of the 264WM, 260 Nosler, the Sherman's, etc. cross the divide into what one would think of when seriously considering 6.5 magnum territory, IMO.
