The real interesting thing about the FN is that when the P90 was in development, they were aiming at caseless ammo with a square profile, 100 to a mag and no ejection. A guy I knew - editor or “Våpenjournalen” - actually had a tester for a while.
Don’t know why the concept was abandoned, but it seems undocumented today.

Lots of development money has been spent on caseless ammo. The problem is that it never works as well as cased ammo.
It can be made to work fairly well, it just has never been made to work as well as cased ammo, and the advantages are not enough to make up for the disadvantages.
Cook off has always been a major problem with caseless ammo.
