Cartridge designers have struggled with 2.26 OAL, and having enough room for increased case capacity. The 6mm MAX has unlocked the code on the .378 bolt face AR-15 cartridge. It is a brand new cartridge designed for the unmodified mil-spec .378 bolt face, and a full mass bolt carrier group. The 6mm MAX is pressure tested to SAAMI standards of 55k psi.

New and improved super round or just another wannbe to fade into obscurity? Time will tell.
Personally, I've never been much on the latest and greatest thing. I find that long established cartridges can fill all my needs just fine.
