.30-40 Krag

Uncommon card · No. 137618

The .30-40 Krag, also known as the .30 U.S., .30 Army and .30 Flanged Nitro Express (Purdey) was a rifle cartridge developed in the early 1890s to provide the U.S. armed forces with a smokeless powder cartridge suited for use with modern small-bore repeating rifles to be selected in the 1892 small arm trials. Since the cartridge it was replacing was the .45-70 Government, the new cartridge was considered small-bore at the time. The rifle ultimately selected for use by the Army was formally adopted as the M1892 Springfield, better known as the Krag–Jørgensen from the Norwegian designers' names. The cartridge was also used in the M1893, M1895, M1897, and M1900 Gatling guns.
