Iron cannonballs are ammunition used for a boat cannon during boat combat. They can be fired from iron cannons or stronger.

Four can be made from a single iron bar with level 20 Smithing, granting 17 experience per bar. Smithing cannonballs require the use of an ammo mould, which requires partial completion of Dwarf Cannon to obtain. Alternatively, a double ammo mould (requiring Foundry Reputation to purchase via the Giants' Foundry minigame) allows players to process two bars into eight cannonballs at the same speed as a regular ammo mould processes one bar into four.

Players with level 87 Sailing can further speed up smithing cannonballs by using the ancient furnace in the Grimstone Dungeon, which halves the time it takes to create cannonballs from 8 ticks to 4 ticks. Combining this with a double ammo mould, players can smith cannonballs at four times the normal speed.
