Cannonball

Cannonballs are ammunition used in the Dwarven Multicannon. They can be made by using a steel bar on a furnace, giving 25.6 Smithing experience per bar. They are made by having an ammo mould in the players inventory and clicking on steel bar, then on a furnace. Four are made at a time, and they require level 35 Smithing to make. It is quite a good way for members to make money because they can sell for quite a lot in large quantities.
