Sig's cartridge is like 80,000 PSI, which is why it has a steel case head... thats 15,000 PSI above a .270 WSM, which is already nuts. I think they're trying to achieve that performance out of a 16 inch barrel, which is why the suppressor is mandatory... its basically a 270 WSM+15k PSI extra with a faster burning powder out of a 16"-ish barrel. Instant ear death.
I just don't understand the long game involved in the transition... there's gotta be something more compact for the high speed crowd, but a cartridge like Sig's is gonna be a doozy to deal with in a SBR unless you do start complicating things (integral suppression, constant recoil, lower cyclic rate, etc)
Call me a Fudd it looks like they basically want to shoot a .270 out of a fancy .308 case that can't be reloaded...

One of the Sigs (I don't know if it's this one or the new IAR weapon) has a reciprocating barrel to offset the kick. I thought that was bonkers
