Crazy: Nope, not the same round at all. The 7.5mm Swiss Army Revolver round came in both smokeless and black powder and is fully interchangeable with the 7.5mm Swedish and Norwegian rounds, if you can ever find any. Norma made ammo for the Swedish Nagantand this ammo can be used in the Swedish revolver. I think Fiocchi still makes the ammo. It's about on par with the 32 S&W long.
The round appears to be a slightly tapered revolver rimmed round with a very slight bottleneck - sort of like going from 8mm to 7.5mm, that slight. It is not a powerful round, firing a 100-110 gn lead bullet at approximately 700'/sec. The revovlers were said to be well made and nicely finished in contrast to the Russian Nagant. HTH.
