The Krag-Jorgensen: America's First Bolt-Action Service Rifle..

https://www.americanrifleman.org/content...-service-rifle/

The Spanish-American War of 1898 was America’s last war of the 19th century and began the ascent of the United States toward world power. It also marked the first major combat use of the U.S. Army’s new .30-40 Krag-Jorgensen service rifle. Adopted in 1892, and placed into production at the venerable Springfield Armory in 1894, the Norwegian-designed Krag-Jorgensen was intended to replace the ponderous and obsolete single-shot, blackpowder .45-70 Gov’t Trapdoor Springfield.
