22 pounder guns?

I have never seen a 22pdr gun before, but supposedly, Hillebrant Quast's ship, the Hollandsche Tuin, carried two of them in 1631. For a ship of 180 lasts, the Hollandsche Tuin was heavily armed, as it also carried 6-18pdr guns. The 22 pounders were bronze chambered guns, while the 18 pounders were bronze guns. A ship of 180 lasts might have dimensions of 120ft x 28ft x 11ft.
