In Brophy's The Krag Rifle, he quotes from the 1893/94 reports from the Chief of Ordnance - "The regular manufacture of service ball cartridge ammunition for the .30-caliber magazine rifle, model 1892, using smokeless powder of domestic production (Peyton), was commenced at the Frankford Arsenal in May last, and up to the end of June about 200,000 rounds had been made and issued or placed in store."
According to Hackley, Woodin & Scranton in History of Modern U.S. Military Small Arms Ammunition Volume 1: 1880-1939 (Macmillan Co.1967) compressed black powder loads were tested during the initial developmental efforts (c.1889) - but velocities were extremely low. It appears that the first cartridges loaded with smokeless power were produced in September 1890. Blank (1893) and Gallery practice (1895) cartridges were initially loaded with black power.
