Overcome with curiosity, I did some online research. Values for individual rounds vary somewhat but this list gives a general ranking.

..................(gr. H2O)
7.21 Lazaroni.......117
7 RUM...............114.8
7 LRM...............100
7 STW...............98.3
26 Nosler...........93...(may be slightly more opened to 7mm)
7 Washburn Super..90
7 Wby...............87.5
7 Jarrett...........85.5
7 Dakota............85
7 RM................83.2
7 WSM...............83

So, you see where a 28 Nosler would rank among big 7's. It may go 94 or 95 gr. H2O, opened to 7mm. It's so close to some very established rounds, I wonder if there's a real market niche for another big 7. With us loonies, who knows...

It would have to make dollars and sense for Nosler to roll it out...

They may have found a niche with the 26 Nosler, time will tell, but I would be surprised to see a 28 Nosler in an already crowded field.

IMHO,

Edited to add a couple more.
