History: Introduced as a black powder rifle by Marlin in 1884 for the Ballard target rifle, Winchester began to produce 38-55 caliber rifles shortly afterwards. The 38-55 was later produced in rifles in the smokeless era (examples are: Winchester Model 94 and the Marlin 1893). The earlier 38-55 rifles can be found with a variation of groove diameters, some as large as .382 inches.
