Description:

The .22 LR debuted in 1887 with black powder, achieving around 1,045–1,095 fps. Smokeless powder became viable shortly after (Poudre B in 1884, with U.S. commercial adoption following), and manufacturers quickly adapted rimfires to it due to the cartridge's small case volume suiting efficient, low-bulk smokeless propellants. By the 1910s–1920s, true smokeless standard-velocity loads (no black powder component) became more common. High-velocity smokeless loads (1,200–1,300+ fps) didn't arrive until Remington's 1930 introduction, which differentiated them from the established "standard" profile.
