“Ammo suited for a boat's cannon.”
About this item
Rune cannonballs are ammunition used for a boat cannon during boat combat. They can be fired from rune cannons or stronger. Four can be made from a single runite bar with level 90 Smithing, granting 50.5 experience per bar. Smithing cannonballs require the use of an ammo mould, which requires partial completion of Dwarf Cannon to obtain.

Measured with medians rather than averages, because one spike — an update, a streamer, a brief squeeze — drags an average around for weeks afterwards and makes everything since look ordinary. Worth noting here: this item typically moves 0.15% in a day, which is more than the 0.15% you would be capturing — so holding it overnight risks more than the flip makes.
