Wouldn't that essentially be a 7 saum? And how well was that received by the manufacturers?

What's old is new again. It would essentially be a belt-less 7mm Weatherby. Case capacity almost exactly between a 28 Nosler and a 7mm Rem Mag. Small enough to light H1000 with a 210m yet big enough to reach 3000-3100 FPS with sane pressures and excellent Norma brass. Feeds from AICS magazines with zero drama or modification. Win Win Win for me.
Last April I shot the mile with mine. 180 vldh had good enough ballistics that I was able to dial without holdover
 
Think of it in terms of the 300PRC. A chamber designed with long for caliber bullets primarily. The 300 PRC doesn't smoke the 300 Win Mag on a spread sheet. They actually look pretty similar, but the PRC is a SAAMI chamber with the longest, heaviest bullets. I don't look at it just in terms of velocity. If that were the only motive we could stop long ago at the 7STW, 7-300's, 7 WBY, 7RUM and an exhausting list of other 7's including the Nosler, it was designed to create a 162 gn bolt of lightning... but you can't shove a 180 or 195 in that without creating a bunch of problems. My hope for the 7 PRC was that it would be all of that and and still be SAAMI, for all of the reasons like fitting in the chamber, safely, fitting in the magazine, freely and so on.
The LRM gets noted often when discussing the 7PRC-to-be. It's probably the closest comparable chambering. I like the LRM but for brass. If Hornady took the LRM to market like they did the Creedmoor and PRC's, then I'd be super satisfied. They'd tweek the fitment and in no time, gun manufacturers would make it available, ADG and Lapua and the like would have head-stamped, quality brass and we could all go on to debate the next topic.
So... Since the 7PRC isn't...yet... what next?

Ok. I was thinking the 7prc and 28prc being possibly different names for the same not yet real cartridge. 6.5prc necked up to 7mm.

If Hornady followed precedence the 7 (or 28) PRC would be optimized for the 7mm long bullets - particularly the 180 ELD-M and new A-Tip since they are Hornady.

Think 7LRM without the long neck and standardized design.

Every one of these 7mm cartridges mentioned is missing a piece of the puzzle. At least for the application we're discussing.
 
*Munches popcorn and laughs* I do not know what the big hype is about the 0.284"/7MM. It's a bore diameter I could just never figure why it was ever imported from Europe to America. We had so much better calibers here. the best thing the 7X57 ever did was donate the case for the 257 Robert's and the 27 Shepard. Good Lord! Am I ever going to get hate on this one.. well chaos reins.. my job is over.. back to boxing up guns for shipment.

I'm also not a 7mm lover but I have no good reason besides having had a 270 first. But if I'm being rational, objective, not sentimental, the 7mm is a much better choice today than the .270 because the crippling 1:10 twist rate that dictates there are no true high B.C. 270 bullets that can be used in standard off the shelf inexpensive rifles that hold a candle to what the 7mms have. There's nothing magical about .007 of an inch difference, but that twist rate gets the final say. And if I'm being honest I think anything a big 30 can do ballistically a big 7 can do with a lot less recoil while still being big enough (the difference to my perception of effectiveness between .26 and .28 bores is much greater than the real world difference between 28 and 30s - if I had to start all over I'd probably do the logical thing and get a big 7 of some kind - but I've grown very attached to my .270 win and .300 win mag so that's not gonna happen!)

Hornady did NOT introduce the 7PRC or 28PRC or whatever at the SHOT Show. I can't express my disappointment. My expectation of the 7 PRC was a slightly shortened 300 PRC case, necked down to .28 with 180 ELD-M in a SAAMI chamber launched at 3150 fps with 4-5 grains less powder than the 28 Noz.
So... 7 Sherman Magnum or 7 Max?
