According to SIG the cases are reloadable unlike other military cartridges. Apparently only one rifle/action is available and that’s the military designed SIG MCX Spear. It will be intriguing to see if any manufacture dips into this cartridge in a turn bolt rifle. 80K psi is an inordinately high pressure in a hunting firearm. Shooting a round of that pressure in a firearm is unheard of from a SAAMI perspective throughout history. The highest ratings are around 65K psi to 68K psi for SAAMI ammunition specs. Shooting a steady diet of 80K psi would make me sweat a bit not knowing when two or three lug systems may shear one or all their lugs.
Saw some ballistics on a 2.83” COAL yielding a 135 gr .488 BC at 3,000 fps from a 16” barrel. Same set up moves a 150 gr .591 BC at 2,900 fps. Seems ripe for a short barreled hunting rifle with a can on the end. Question is what action can take a constant 80K psi and maintain the integrity of safe use.
