.30 M1 Carbine

The .30 Carbine is a rimless carbine/rifle cartridge used in the M1 carbine introduced in the 1940s. It is a light rifle round designed to be fired from the M1 carbine's 18-inch barrel. The .30 Carbine cartridge was developed by Winchester and is basically a rimless .30 caliber version of the much older .32 Winchester Self-Loading cartridge of 1906 introduced for the Winchester Model 1905 rifle.
