Size vs familiar rounds

History

John Pedersen designed both the cartridge and the semi-automatic rifle to fire it. Army trials from 1925-1932 showed it outperformed .30-06 in many respects. The Army's Ordnance Board recommended adoption. General MacArthur overruled the recommendation, insisting on full-power .30-06. The Garand was redesigned for .30-06 instead.
