The double ammo mould is an item that makes cannonballs twice as fast compared to a regular ammo mould, making 8 cannonballs rather than 4 (and using 2 metal bars rather than 1) per action.

It can be purchased from the Giants' Foundry reward shop for 2,000 Foundry Reputation if Dwarf Cannon is complete. On average, using Steel-Mithril longswords with only optimal moulds (requiring up to 81 Smithing), obtaining a double ammo mould takes around 75 minutes of gameplay. With only default moulds, it takes 15 minutes more.

This mould can also be used to create the gold cannonball used in the Between a Rock... quest.

With 87 Sailing, the Ancient Furnace can be accessed within the Grimstone Dungeon and used to smelt cannonballs at double speed.
