I think the old 250/3000 savage would be a good place to start. Perhaps neck it up to the 6.8 caliber if needed and build barrels with a one in nine twist. Nice short case without a belt or any other foolishness.
Researching further that is almost exactly what they have done. Case dimensions are within the manufacturing tolerances of the 250 Savage except the neck has been expanded to 270 so bullets for the 270 Winchester will fit. Why they call it a 6.8 is to make it clear it is not a 270W.
Then they added that steel base to allow working pressures of 80,000 needed to get 3000fps out of a 16 inch barrel and use 1 in 7 inch twist to stabilize long bullets.
Still seems like a lot of work for negligible improvement to me and I doubt sniper teams will be clamoring to trade in their 333 Lapuas for one.
