How to flip the Bronze cannonball
The Bronze cannonball is a members-only Old School RuneScape item — “Ammo suited for a boat's cannon.”. Its Grand Exchange buy limit is 11,000 per 4 hours. Right now it buys at 5 gp and sells at 6 gp — a net margin of 1 gp (20.0% ROI) after the 2% Grand Exchange tax. High alchemy yields 1 gp.
To flip it, place a buy offer near 5 gp and a sell offer near 6 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
