The Faule Mette (German for Lazy Mette, alluding to the gun's rare deployment, difficult mobility, and limited loading and fire rate) or Faule Metze was a medieval supergun of the city of Brunswick, Germany. Cast by the gunfounder Henning Bussenschutte on the central market square Kohlmarkt in 1411, it was fitted with a conically tapered muzzle (calibre of 67–80 cm) which allowed the use of projectiles of varying size. Thus, it could fire stone balls weighing between 322 and 423 kilograms (710 and 933 lb) with a gunpowder load ranging from 24 to 33 kilograms (53 to 73 lb).
