Swedish 20x110 unified cartridge

I just have learned that Sweden obviously had different cartridges for different weapons all chambered in 20x110 HS. I was aware of different lengths of projectiles but did not know that Swedish 20x110 variants were not interchangeable.
In the beginning 1960s a “unified” cartridge was considered.

Anybody to tell what the different cartrdges were and what the finally “unified” cartridge was?

Unified usually refers to the Unified thread used,so maybe they had threaded primers?

No thread here, it is about cartridge lengths and likely about gas pressures etc.
Hence my question.
