The .25-21 Stevens was an American centerfire rifle cartridge.[2]

Designed by Capt. W. L. Carpenter, 9th U.S. Infantry, in 1897,[3] the .25-21 was a bottlenecked round, based on the longer .25-25.[4] It was Stevens' second straight-cased cartridge (after the .25-25)[5] and would be used in the single shot Model 44 rifle, as well as the Model 44½, which first went on sale in 1903.[6] In addition, it was available in the Remington-Hepburn target rifle.[7]

While the .25-25 was popular, the .25-21 offered "practically the same performance and was a little cleaner shooting."[8] It was also found the usual 20 or 21 gr (Expression error: Unexpected < operator. or Expression error: Unexpected < operator. g) black powder charge of the shorter, bottlenecked .25-21 offered "practically the same ballistics" as 24 or 25 gr (Expression error: Unexpected < operator. or Expression error: Unexpected < operator. g) in the .25-25. It was highly accurate, reputedly capable of generating .5 in (Script error mm) groups at 100 yd (Bad rounding hereScript error m).[9]

In power, the .25-21 was outpaced by the .25-20 WCF[10] and .32-20 Winchester,[11] while today, even modern pistol rounds such as the .38 Super offer superior performance.[12]
