What is a notable characteristic of the .410 bore shotgun?

The .410 bore shotgun is notable because it does not have a gauge designation like other shotguns do. Instead of being referred to as a gauge, it is designated by its diameter, which is approximately .410 inches. Most shotgun shells, such as 12-gauge or 20-gauge, use a gauge system where a smaller number indicates a larger bore diameter. The .410, however, specifically denotes its caliber, making it unique among shotguns.

The distinction emphasizes the .410’s design and intended use, as it is often favored for small game hunting and by novice shooters due to its manageable size and ease of use. This unique designation sets the .410 apart in discussions about shotguns, making it an essential point for understanding shotgun classifications.
