I think the barrel length thing was an interesting marketing choice. This is just a "super magnum" with another 20K PSI being delivered, allegedly safely, at a high cost per round, and more expensive/challenging to reload. That is still a pretty interesting proposition, and I'll be excited to see this shrunk down. I'd love to be able to push a bonded, high BC, 80+ grain .224, .244, or .25 caliber projectile at 3500 FPS +, while still having okay barrel life, and a short action. I have been reading articles that say "no recoil!", but I'm skeptical. Energy is energy.
This feels like a great North American and African big game cartridge.
