Ammo Brief: .30 Carbine

Don’t kid yourself about the power of .30 Carbine, because it’s just not there.

In 1940, the U.S. Ordnance Department concluded that a light carbine might have certain advantages over the .45-caliber semi-auto pistol in many combat situations. Various designs were submitted by a number of private manufacturers, and, in the end, Winchester’s offering was selected.

The semi-auto .30 M-1 Carbine was officially adopted in 1941. Its cartridge, a modification of the .32 Winchester self-loading round of 1906, was hardly a revolutionary design, but it served the purpose. About the same time, the Germans developed their assault rifle and the 7.92mm Kurz (short) cartridge. The M-1 Carbine isn’t an assault rifle, and the military insists it was designed to fulfill a different purpose. A few sporting rifles and handguns have chambered the .30 Carbine.

In mid 1963, the government released .30 M-1 Carbines for sale to civilians through the National Rifle Association at the very moderate price of about $20. Thousands of these rifles, as a result, have been used for sporting purposes. Federal, Winchester and Remington load soft-point sporting ammunition.

The .30 Carbine cartridge is in the same class as the .32-20 WCF, but slightly more powerful. It’s wholly a small game and varmint round, despite contrary claims by those who love the short, light and handy M-1 Carbine. The modest accuracy of the carbine, combined with the ballistics of this cartridge, limit the effective sporting range to about 150 yards. The original author of Gun Digest’s Cartridges of the World used an M-1 Carbine to hunt small game and deer as early as 1943, before most people could get their hands on one of these guns, so he had a pretty good idea of the capability of the cartridge.

Remember that the .32 Winchester self-loading round became obsolete in 1920, because it was ineffective and more or less useless for sporting purposes. The .30 Carbine was derived from that round and shares the same shortcomings. However, it can shoot relatively cheaper military ammunition, and this allows use of the gun in many situations not economically feasible with the .32 SL.

However, don’t kid yourself about the so-called “terrific power” of the .30 Carbine cartridge, because it’s just not there. Despite this, it can be a very useful cartridge within its limitations, and its use and popularity have increased considerably over the years.

One final note: Had the military adopted a normal, modern rifle pressure standard, instead of the inexplicably modest 40,000 psi specified, we might have a somewhat different opinion of this cartridge. Loading to normal .30-06 pressures provides about 400 fps more velocity, which seems significant.
