rimfire. ( 1 of a cartridge) having the primer in a rim encircling the base. Compare center-fire (def 1). ( 2 of a firearm) designed for the use of such cartridges.
The first rimfire cartridges were .22s, but after the type became established many larger caliber rimfire cartridges were developed in the mid to late 19th Century. Some of these had a good run of popularity until they were superceded by the development of higher pressure centerfire ammunition. Calibers ranged from the .25 Short to the .58 Miller. Probably the best known of the larger caliber rimfires are the .25 Stevens, .32 Long, and .44 Henry Flat. The latter was the cartridge for which the seminal Henry and Winchester 1866 Yellow Boy lever action rifles were chambered.
