History
Italy adopted this as replacement for 6.5 Carcano in 1938, seeking better terminal performance. Limited production began but WWII disrupted conversion. By 1940, Italy was converting rifles back to 6.5mm due to logistics nightmare of two calibers during war. One of history's most poorly-timed cartridge introductions.
