M1 30-06 Garand vs. .30 Carbine

[Maverick223]

Does anyone know why the War Department didn't require the carbine be chambered for the .45 ACP?

I would suspect range and weight both played factors. The .30Carbine is good for about 250yds or so (sight goes to 300yds, but that is a bit farther than practical IMO), whereas a .45ACP would be good for about half that (just too much elevation needed). The heavier .45cal bbl and ammunition would also have made the carbine chunkier, heavier, and hold fewer cartridges in the magazines (probably 10 instead of 15). Also the .30 carbine has more energy (whilst retaining it for longer distances), and is better suited to longer barrels than the .45ACP (because of the powder used and case capacity). I believe the cartridge choice was a good one...in fact I would love to see more rifles chambered for it (particularly the FN PS90).

I got both at the same time, more or less. I got them for collector's interest and not fo much else, although I do plan to shoot them one day.
