Is 20mm considered a cannon?
The 20 mm caliber is a common firearm bore diameter, typically used to distinguish smaller-caliber weapons, commonly called “guns”, from larger-caliber “cannons” (e.g. machine gun vs. autocannon). All 20 mm cartridges have an outside projectile (bullet) diameter and barrel bore diameter of 0.787 inches (20.0 mm).
What gun shoots a 20mm round?
The M61 Vulcan is a hydraulically, electrically or pneumatically driven, six-barrel, air-cooled, electrically fired Gatling-style rotary cannon which fires 20 mm (0.787 in) rounds at an extremely high rate (typically 6,000 rounds per minute).
