I would think it would be in some pretty good company...
But I don't think they will make one...
There are lots of magnum 7mm's out there; not so many magnum capacity 6.5's, which is the niche I think Nosler is trying to fill.
A factory 28 Nosler, IMO, isn't going to happen for the reasons you point out.
BUT, for us Loonies, won't necking up the 26 Nosler to .284 be a real easy way to get a Mashburn wannabe...?
Brass prep would sure be a lot easier. Neck up and go shooting. Can't get much easier than that. That's about the same as forming .22-204 cases. Transforming brass from .204 to .22 204 is so easy it's probably not fair to the .223AI fireformers...
Just had to say that...
