A LOT More interestinmg to KNOW what Powder and how Much of it ! Primers aren't getting it DONE !

Certainly going to take a year or five to see what real results will be. Folks will have to make sure chambers are dry, don't want to be running on any sort of wet chamber with this stuff, that could wreck something PDQ. Short to medium action stuff would be the market they'd want to dominate at this point, I'd guess. Could see them wanting to upgrade the 308 case based stuff like a 22CM or a 6mmCM and 25CM, maybe even a 7mmCM sized round, would seem to maybe be a practical path for the commercial market. With what got described in the Area419 vid there, probably some expensive tooling, so, may be a slow rollout. Who knows what they have for parameters to work in to test what cases, ie; do shoulder angles matter on them, does one angle make a difference over another, thus excluding an older cartridge from getting the treatment. Then there is what can or will barrel & gun mfgrs say or do with or about this stuff, what will SAAMI or CIP do with testing in regards to it and recommending usage, or not. Guessing there is a fair bit of info from the military side we haven't really heard much about yet, from the various trials they've run on the high pressure stuff, probably all classified at present.
I don't know, way over my head in many regards.

Federal using the word "comparable" to bypass liability... IMO
The millisecond the primer ignites the powder, the bullet unseats from the case mouth. At that exact moment, the high-strength steel case ceases to be a closed containment vessel. The pressure is no longer just "kept within the alloy case"—it floods directly into the throat and the first few inches of your standard / custom.barrerl.
Peak Alloy steel case survives the 80,000+ PSI perfectly, allowing it to be extracted and reloaded without splitting.
and.near the exact.same.time...
Your rifle barrel is not made of Peak Alloy steel; it is standard 416R stainless or chrome-moly steel.
The moment the gas escapes the case mouth, that unshielded barrel throat is slammed by a pressure spike 30% higher than standard 6.5 Creedmoor limits.
No magic physics...
Or more likely the Shooter
But peak pressure is typically reached when the bullet is 1-3" into the barrel, so it can't be JUST the case...
Do the physics flip? They certainly COULD, but i haven't seen anything that really convinces me one way or the other on this.
I'm not saying you're wrong. I'm saying I don't know, so if you've got something to show that supports your assertions please share with the rest of us - and please explain yourself. Simply giving the name of a law doesn't help us understand when we don't know what that law means or how to apply it.
Maybe some people will use it for PRS. Depends on accuracy. A faster cartridge will buck the wind better for 1000y shots. We will see how they reload to. For the amount of money PRS shooters spend burning a barrel isn't a big deal.
There's a huge market for 6.5cm hunters. I'd be surprised if they'll have enough production to keep up with demand. I imagine many will be scalping for elk and moose season. They probably released the 6.5 after realizing their production capacity was to large for just proprietary cartridges.

Dude! The barrels are literally designed to withstand and exceed the sammi levels though! What's your deal with hating on this. You've ignored every argument and even negated the input from the ballistition who designed this case. Just stop. You have 0 hands on experience with the case, stop speculating like you know better than a guy with a frigging degree in rocket science who works at federal lol. You're killing me lol. Like do yourself a favor. Please. READ ARTICLES RELATED TO THIS ROUND. they literally built guns around this clambering.. seekins for example. Read first, then form your opinion.
Well that is a Fact as primers normlly BLOW out because of primer pocket Over Expansion in size ! - The metal case is supposed to stop that expansion like it does with the 7 BC cartridge . I will assume they will be using the same primer in the Super 65 CreedMore !
