If you want to take it enough further... After WWII the British begged us to adopt their new .280 British cartridge. Which the U.S.Army Ordinance refused to do insisting instead on the more powerful 7.62 NATO cartridge.
Decades later the U.S. Special Operations Command orders a new cartridge, the 6.8 SPC, due to their dissatisfaction with the performance of the weak standard 5.56 NATO cartridge.
The connection is that the 276 Pederson, the .280 British, and the 6.8 SPC cartridges are all ballistically alike. So the original modern smokeless army cartridge may still be the best. And the U.S. Army has been running circles around the obvious ballistic choice since 1898!
