Small-bore refers to calibers with a diameter of .32 inches or smaller. [1] It may also refer to small-bore rifle competition. The medium-bore refers to calibers with a diameter between .33 inches up to .39 inches and large-bore refers to calibers with a diameter of .40 inches or larger. [2] Miniature bore refers historically to calibers of .22 inches or smaller.
There is much variance in the use of the term small-bore which over the years has changed considerably with anything under .577 caliber considered small-bore prior to the mid-19th century. [3]
