I understand your point, and I can't fault your logic, but then it wouldn't be an authentic .280 Ross. If I were going to build a custom rifle with a new chambering and only using a Ross action, I'd go with .264 and open a whole world of potential. Or maybe a .300, if I were going to go hunting something big. I've seen a very tidy-looking .300 Win Mag (unfortunately made from an M-10). The result would be more appropriate on the nitroexpress or AR forums, of course. On the other hand, if I wanted to build a true replica of a classic Ross Deer Stalker, it wouldn't feel right going to all that work and ending up with some fan-boy Creedmoor, or a Blaser wannabe. Just my feeling.
