22pdr guns?

The Noorderkwartier ship Hollandsche Tuin, in the Staat van Oorlog te Water for the year 1633, is listed as carrying two chambered bronze 22pdr guns. The 22pdr is a very odd size. Most Dutch guns close in size to this fired a 24 pound shot. A very few fired a 20 pound shot. I had assumed that when I first saw this size mentioned that it was a mistake, but now I think it is correct. One of the old Rotterdam ships was listed as carrying 22pdr guns, and I had thought that it must be wrong, but it was probably correct.
