There is a ton of information on the TFB interviews with the program manager.
Many technical details have emerged that are rather interesting, and have potential implications that would turn the entire metallic case industry on its head.
There's a polymer plug up front that the bullet seats in, which seals the breech under pressure. They are seeing better accuracy because it's easier to make a concentric polymer plug than brass, and the projectile is not exposed, so no opportunity for applying force to the side of the projectile during feeding.
The propellant is conventional powder, only highly compressed as close to a solid as possible, which improves performance in both ES and velocity.
She also gives the history and initial vision of the project. There are 3 parts already, with weekly updates.
