I'd love to see it too. Would give me an idea of their proof barrel for example.
I get physical dimensions, and energy requirements, but 2 of those rounds I mentioned had energy below 400. So either they are using a far shorter barrel than the STANAG protocol, or don't meet NATO specs and can't be NATO rounds. I think that is the case with Winchester White box. Lots not passing acceptance testing.
I don't expect the velocity out of my S&W 6906 or KelTec P-11 to be as high as a 5" Beretta 92, but at least knowing what barrel those numbers are based on would help.
