How to flip the Steel cannonball
The Steel cannonball is a members-only Old School RuneScape item — “Ammo suited for a boat's cannon or for a dwarf multicannon.”. Its Grand Exchange buy limit is 11,000 per 4 hours. Right now it buys at 205 gp and sells at 208 gp — a net margin of -1 gp (-0.5% ROI) after the 2% Grand Exchange tax of 4 gp. High alchemy yields 3 gp.
To flip it, place a buy offer near 205 gp and a sell offer near 208 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
