History: The .28-30 Stevens was one of the more unusual American cartridges of the early 20th century, using a .28 caliber bore in a period when most American cartridges were .22, .25, .30, .32, .38, or .44. Chambered in Stevens 44½ and Ideal single-shot actions, it remained a niche offering through the early 1900s.
