if it could carry it and was built with the specs for it, then it should have it in game 425 or 500, max payload should be allowed per gun!
just because they did things different in the field does not mean, thats the way we should do it here! many jugs had field fitted props that we don't have, bubble canopies that we don't have,ect.ect.ect.
the main argument that has come out before is that if it did not roll of the assembly line with something, then we don't get it in game, ( paddle props) even tho they helped the plane greatly in the field!
so just because not many ever used the full ammo package in the field has nothing to do with what we should or should not have in the game!
this game is not historically correct to WW2 anyway, it is a close facsimile, but not perfect! now leave My "M" alone,,, darnit!!!
