And here are some extremely rare instances of iron clod shot of rectangular or many-sided shape, all 14th to 16th century and all cast in molds, and all covered with a leaden coating to protect the relatively 'soft' inner walls of bronze barrels.

Breaking the sharp edges of an iron clod was the easiest and closest approach to the ball shape. I own a 14-sided specimen of enormous weight and size that clearly shows traces of a two-piece mold (images to follow).

From Mary Rose (sunk in 1545) finds we know that Henry VIII's army used such lead-clad iron shot to break the oak rumps of ships in sea fights; they have been analyzed by neutron tomography and Roentgen rays (see attachments).
The two attachments showing iron cubes dug up together with fragments of bronze cannon and the bottom piece of a bronze wallgun barrel are most interesting!
