.30-40 Krag Blank Ammunition (For use in Real Guns) Box of 20
The .30-40 Krag, also known as .30 U.S. and .30 Army, was developed in the early 1890s and became the first smokeless cartridge used by the United States Army. It was modeled after the .303 British, which has a similar geometric shape. The Army also adopted a standardized loading of 220 grains.
Blank cartridges will not cycle automatically without the use of a blank-firing adapter.
