Springfield Model 1892–99

Like many other armed forces, the U.S. Army searched for a new rifle in the early 1890s to replace their old Springfield Model 1873 "trapdoor" single-shot rifles. A competition was held in 1892, comparing rifle designs from Lee, Krag–Jørgensen, Mannlicher, Mauser, Schmidt–Rubin, and about 40 other military and civilian designs. The trials were held at Governors Island, New York. Despite protests from domestic inventors and arms manufacturers—two designers, Russell and Livermore, even sued the U.S. government over the choice—the Krag–Jørgensen design was chosen by the board of officers.

Approximately 500,000 "Krags" were produced at the Springfield Armory in Massachusetts from 1894 to 1904. The Springfield Krag rifles and carbines had been introduce into combat in the later years of the American Indian Wars where its performance surpassed the Trapdoor rifles and carbine where as the Trapdoor was single shot weapon but the Krags were five shot. It was the U.S. Army's primary rifle from 1894 to 1903 (when it was replaced by the M1903 Springfield rifle with its ballistically similar .30-03 cartridge), and found use in the Spanish–American War and the Philippine–American War. In this later war the rifle was referred to in a song popular with U.S. troops, a parody of "Tramp! Tramp! Tramp!", with a verse running:

Damn, damn, damn the Filipinos!
Cut throat kha-ki-ak ladrones!
Underneath our starry flag,
Civilize 'em with a Krag,
And return us to our own beloved homes.

According to contemporary, perhaps sensationalized accounts, the Krag's complex design was outclassed[1] by the 7mm 1893 Spanish Mauser during the Spanish–American War, and proved ill-suited for use in tropical locales such as Cuba and the Philippines. American soldiers found themselves unable to match the volume of fire displayed by the Spanish 1893 Mauser rifle, with its internal box magazine that could be quickly and fully reloaded with five-round stripper clips, and a high-velocity, flat-shooting 7mm cartridge which was quickly dubbed the "Spanish Hornet".

During the American assault on the strategic Cuban city of Santiago, a small force of 750 Spanish troops armed with Model 1893 Mauser rifles defended positions on San Juan and Kettle hills. The attacking force consisted of approximately 6,600 American soldiers, most of them regulars, armed with the then-new smokeless-powder Krag–Jørgensen rifle and supported by artillery and Gatling gun fire. Though the assault was successful, the Americans soon realized that they had suffered more than 1,400 casualties in the assault. A U.S board of investigation pinned the blame on the superior firepower of the Spanish Model 1893 Mauser rifles, although modern analysis has determined that many of the casualties were due to superior Spanish fortifications on the high ground. With the Krag's replacement with the Mauser-derived M1903, the rifle is tied for the shortest service life of any standard-issue firearm in US military history (1892–1903).

The Krag was phased out of service with the regular Army by 1907, as M1903 Springfields became available; however, the Krag was issued for many more years with the National Guard and the Army Reserve, including service in World War I with rear-echelon U.S. troops in France and as training arms at various Stateside bases. Phased out Krag rifles and carbines were also used by law enforcement agency such as the U.S Marshals, Texas Rangers Division, and even bounty hunters and local town sheriffs and deputies in the American frontier. Later, many were issued to veterans' organizations such as the American Legion, Sons of Union Veterans of the Civil War, and the Veterans of Foreign Wars for use in military ceremonies. Still others were sold to civilians through the Civilian Marksmanship Program, and American Krag rifles are a popular and common military surplus collectible.

The U.S. Krags were chambered for the rimmed .30-40 Krag round, also known as ".30 Army." From 1890 to 1893 a 230-grain steel- or cupro-nickel-jacketed bullet was issued, for which no ballistic data is known. From 1894 to September 1899 a 220-grain jacketed bullet loading was issued using 40 grains of nitrocelluose powder, which developed some 40,000 psi and a muzzle velocity of 2,000 feet per second (610 m/s) in the Krag rifle and 1,960 ft/s (600 m/s) in the shorter carbine.

In October 1899, after reviewing the experiences of the Spanish–American War, a new loading was developed for the .30 Army in an attempt to match the ballistics of the 7×57mm Mauser cartridge. The new loading increased the Krag rifle's muzzle velocity to 2,200 f/s at 45,000 psi. However, once the new loading was issued, reports of cracked locking lugs on service Krags began to surface. In March 1900 the remaining stocks of this ammunition, some 3.5 million rounds, was returned to the arsenals, broken down, and reloaded back to the original 2,000 ft/s (610 m/s) specification.

Although the .30-40 Krag was the first smokeless powder round adopted by the U.S. military, it retained the "caliber-charge" designation of earlier black powder cartridges, thus the .30-40 Krag employs a .30 caliber (7.62 mm) bullet propelled by 40 grains (3 g) of smokeless powder. As with the .30-30 Winchester, the use of black powder nomenclature led to the incorrect assumption that the .30-40 Krag was once a black powder cartridge. As such, the .30-40 Krag round was one of the last cartridges to be named in this fashion.
