The 7mm PRC on the otherhand I'm not convinced about, for no other reason than I think it should've been short action length.
For this reason only I think the 7mm SAUM will be sticking around and won't be "killed off" like 300wm, 6.5SAUM and 260 effectively have been by other Hornady cals. I know they haven't actually been killed off but I think over time the PRCs will be the clear winner as far as factory rifle offering go.

The trend and best use case for magnums is long heavy for caliber bullets. In 7mm this is 180's. This is right at the edge of magazine length for a S/A. Combine this with a very fat case to get enough powder in to the short magazine and you have a cartridge that needs to be individually tuned for feeding, and even then can be unreliable. Not ideal in a factory chambering.

The long action makes way more sense imo. Better form factor for feeding, way more mag space and only a small sacrifice of weight/length.

These new cartridges are less about making something new and more about improving on an existing formula, then making it readily available with a bit of good old fashioned marketing.

Cant argue with your logic, the only counter point would be the better inherent accuracy of the short fat type cases

This is a 30-06 length cartridge (OAL 3.340”) with base the same as 300WSM ( 0.535”).
So it not a modernised 7mm Rem Mag. Wont match its ballistics but it doesn't need a H&H sized action.
A solid step up from 284win and the WSMs and SAUMs. An extra half inch of case will go a long way.
This could position itself as a grunty all rounder for NZ hunting.
Are any factory actions made for this combination of bolt face and length yet ?

It should better the ballistics can a rem mag push a 180 3000fps out of a 24” tube? I suppose it probably can with the right combo I ran 175s pretty fast once but it was way over pressure cases were one and done I typically used the 162amax and 2225 for 3030fps
