Just read this article at pop mech very interesting. They say it's 40% lighter and has 300% more energy however it is slightly wider than traditional cartridges so the rifle would have a 20 round magazine instead of 30 rounds, and the rifle would weigh a little more. "Is losing a third of available ammo and adding three-quarters of a pound to the rifle worth 300% increase in bullet energy". I say yes, a 6.5mm round that hits like a 338 Lapua? Yes, please.

Very interesting. I am wondering about accuracy. The bullet doesn't appear to seat in the breach like a normal round. I could also see issues with the breach as well because of that. I would really like to know more on the testing when it goes down. It does sound promising.
