You're correct as always, JB. But your reasoning also makes the 7-08 "redundant." Yet, it sells pretty darn well. I'd bet the 25-08 would, too. Redundant or not.
Heck, as we have both pointed out many times, there's hardly any practical difference among dozens of currently chambered rounds. In essence, half the cartridges made today are redundant. Or more than half. Yet, there are markets for almost all of them, and it's darn hard to predict which new ones will succeed or fail. Some new ones eclipse older ones, and some new ones fade away while older ones persist. And, some new ones parade right along with the equally popular older ones, even though they are redundant.
