Cannon were cast in molds of clay, suspended vertically in a pit. Normally, they were cast breech down; this placed the molten metal at the breech under pressure, resulting in a denser and stronger alloy around the chamber, the most critical point.

How are cannon barrels made?
Since the 70s cannon barrels are made from ATSM A723 nickel-chrome steel which replaced 4335V which was used before WW2. The barrel is hammer forged and then goes thru a process known as autofrettage in which the barrel is expanded out from the inside. After the outside dimensions are machined.
