Unbridled Rage said:IF I recall correctly, the M-1 Carbine was produced in numbers for WWII trench warfare. It was decided that the 30-06 was too much cartridge for the trenches, so they developed a straight-wall .30 cal cartridge called the (?) .30 carbine (?). Ballistics of 200 grain / 2000 fps, much less bang for the close spaces.
