Hi. I noticed that in wikipedia in English, the muzzle velocity of Bofors 57mm m/47 is described as 686 m/s (2,250 ft/s) HE and 744 m/s (2,440 ft/s) AP, and for wikipedia in Swedish, it's 700 m/s, while the book "The Machine Gun Volume III" provided a chart with 2300 ft/s AP and 2440 ft/s HE. I am confused as there is a clear conflict. What is its actual muzzle velocity?

Welcome to the site.
It looks like somebody confused the HE ad AP markings on the Wikipedia site. It is quite common there and ther eis a lot of mistakes in the data for the many subjects. So I wouldn't follow the Wikipedia rather. The minior differences in the numerical values ( 2250 - 2300 ) seem to be the result of converting from the ft/s to m/s.
