Calhoon cartridges are a class of .19 (4.85 mm)[citation needed] caliber cartridges created by James Calhoon, a firearms designer with an interest in that bore size. Calhoon began working with .19 caliber after his interest was piqued from learning about British sub-caliber rifle trials in the early 1970s. The .19 caliber rifles have thicker rifling than .17 and .20 caliber rifles, which helps the barrels stay clean longer and improves barrel life.[2]
