The cartridges are dimensionally identical. The major difference is a slight difference in chamber dimension for one of them. This makes one of them dangerous to fire in the other due to potential pressure spikes.
Forgive me for not keeping better track of this, but I don't have anything chambered in either cartridge.
From the marking on the ammo box you report, one would understand it can be fired in either chamber. Which would logically suggest it is low pressured enough not to disturb anything in either chambering. Perhaps the 'fine print' on the box or the manufacturer's website could resolve your qualms?
