.30 M1 carbine (7.62×33)
This cartridge was born in 1940 from the US Army’s “Light Rifle” project, which was intended to provide military personnel (that is normally not issued with standard rifle) with handy carbine instead of the very marginally effective handguns. The project succeeded, and great many carbines and cartridges for them were made during WW2 and shortly afterwards. This ammunition was extensively used during WW2 and Korean war, but after that it’s use rapidly declined. Originally it was chambered in only one type of mass-produced weapon, the US M1 carbine (and its variations M1A1, M2 and M3). Several countries (i.e. France and Italy) attempted to produce experimental assault rifles for this cartridge in late 1940s, but none succeeded. The only weapons of relatively recent design and manufacture to fire this cartridge are Israeli “Magal” police rifle and Brazilian Taurus TC-30 carbine (also intended for police use). Ammunition in this caliber is still loaded commercially as there’s still many M1 carbines around in civilian hands. Few handguns (pistols and revolvers) were built over the time to fire this cartridge, but firing .30 Carbine round from short barrel usually results in extensive (some say: spectacular) muzzle blast and flash.
By modern standards, this round somewhat lacks effective range and power, but it is nevertheless an effective round for police use and self-defense, with effective range being about 200 to 300 meters from a carbine. It also outperforms most common pistol cartridges (i.e. 7.62×25, 9×19 Luger or .45ACP), fired from submachine guns, in terms of muzzle energy (when it is fired from carbine barrel) by about 100% at all practical ranges.
