Thats pretty cool
I agree, but I an curious about how it would perform
Absolutely - who knows, if the military ends up going with the new high-tech cartridge, and orders a gazillion rounds, that modular cartridge case that can handle 80,000 psi could become the “new normal”...
I was gonna say, they’re not worried about dissimilar metals corrosion?

Strange their going to the equivalent of the .270 Cal that was tested and approved of the 1930’s and stopped by MacArthur because we had millions of rounds of .30 cal ammo
Why is the Military allergic to the 6.5 CM? I know, high pressures and it can wear out a barrel. That is a concern for a hunting rifle, not a military spec barrel. If the 7.62 was more than good enough at distance, the 6.5 CM is even better.
Reach out and touch someone? 6.5CM will get it done.
That would depend on which hat was being worn.
So basically the same energy and stopping power as the Russian 7.62x54R with increased complexity and cost, and lower reliability?

More like about the same energy and stopping power as 7.62 NATO, in a rifle weighing about the same as the AR-10, with increased complexity and cost, and lower reliability. And increased barrel wear.
That O ring is actually a metal locking ring it’s not rubber or plastic. This is some sexy cutting edge ammo. 80,000psi is tank gun level pressures which also use two or three piece cases of bimetal construction for the same reasons they are being used here to get max psi without blowing off your case head. These will be stainless steel case heads so rust is not a factor. The Chinese and the Russians both have used exclusively steel cases for small arms ammo since the 1940s they fought a ten plus year war in the jungles of Vietnam with steel steel.cases being transported by oxen carts down a muddy trial in the rain and elements if anyone was going to rust ammo it was then. Steel cases are coated in lacquer that is baked on like am enameled cast iron pan it is physically part of the case you can try to file it off with a grit file and you will just break a sweat trying that’s why rust is a nonissue the primers are also lacquered rendering the cases effectively water proof. The AK47 famously can and will fire underwater with it standard issue lacquered steel cases rounds for this very reason.
