The .25-21 Stevens was an American centerfire rifle cartridge.[1]

Designed by Capt. W. L. Carpenter, 9th U.S. Infantry, in 1897,[1] the .25-21 was based on the longer .25-25.[1] It was Stevens' second straight-cased cartridge (after the .25-25)[2] and would be used in the single shot Model 44 rifle, as well as the Model 44+1⁄2, which first went on sale in 1903.[2] In addition, it was available in the Remington-Hepburn target rifle.[1]

While the .25-25 was popular, the .25-21 offered "practically the same performance and was a little cleaner shooting."[2] It was also found the usual 20 or 21 gr (1.30 or 1.36 g) black powder charge of the shorter, bottlenecked .25-21 offered "practically the same ballistics" as 24 or 25 gr (1.56 or 1.62 g) in the .25-25. It was highly accurate, reputedly capable of generating .5 in (12.7 mm) groups at 100 yd (91 m).[1]

In power, the .25-21 was outpaced by the .25-20 Winchester[3] and .32-20 Winchester,[4] while today, even modern pistol rounds such as the .38 Super offer superior performance.[5]
