Not sure I buy this. Brass acts like a heat sink removing heat from the platform. I doubt polymer has the same effect as brass. Also curious about reliability/load specs/barrel life.
This looks like an old infomercial by True Velocity to try and bolster their NGSW bid.
The us.mil has already awarded the contract for the NGSW XM5 and XM250 to SIG, chambered in SIG's proprietary .277 Fury cartridge. It was a package deal, both the weapon and the ammo.
I don't foresee the us.mil stocking two completely different cartridge types, in the exact same caliber, that can't be chambered in the other weapon type.
This plan to convert M240's will either be switched over to try and rechamber to the .277 Fury cartridge going forward, or be shit-canned entirely.
