An interesting read, thanks for posting, seems like they are trying to redefine the laws of physics. It is unlikely you are going to put something in the field with more legs than the 7.62x54R without matching it's capacity for powder and bullet weight. Whatever magic you can apply to a modern whiz-bang cartridge case, with modern propellants and optimized projectiles, you can also apply to the 7.62x54R. As the old saying goes, there is no free lunch. You may be able to make the case shorter and fatter, ala the super short magnums, to fit in a shorter action. You may be able to utilize longer, heavier projectiles, with better profiles, to carry out further and flatter. You will never overcome sheer case capacity though.
