Here is what the factory bluebook lists:
If they were other factory chambered calibers, SBHVA or rudybolla would know better than I.
As to maximum working pressure, I don't think we know that. Given that most of the factory chamberings started out as black powder cartridges, I would guess it would be in the 15,000-30,000 PSI range, but that is only a guess and not a fact. The rifle and the cartridges were intended for Swedish grouse (tjedde) hunting and other small game.
