Demi-culverin

The demi-culverin was a medium cannon similar to but slightly larger than a saker and smaller than a regular culverin developed in the late 16th century. Barrels of demi-culverins were typically about 11 ft long, had a calibre of 4 in and could weigh up to 3400 lb. It required 6 lb of black powder to fire an 8 lb round shot (though there were heavier variants firing 9 lb or 10 lb round shot). The demi-culverin had an effective range of 1800 ft.

Demi-culverins were valued by generals for their range, accuracy and effectiveness. They were often used in sieges for wall and building demolition.
