I increased the barrel capacity to 500, but it has no effect on my save, the barrels still only carry 50... Do I have to start a new factory for it to work or is there something wrong?
EDIT: Please ignore this, I found the culprit: I was using this mod together with DellAquila's No Empty Barrels mod, which defaults all barrels to 50. A simple .lua edit of that mod and it works now.
