bmash,
Sounds like headspace.
What is the headspace difference between spent/fired cases from the Lilja, and sized/unfired rounds? Do you know how to measure this?
A related check is to separate the gun and pull out the BCG. Barrel pointing to the floor and drop a loaded round into the chamber. Push on it with your thumb to mimic the bolt slamming it home. Then turn it upright with the barrel pointing at the ceiling and see if it falls out by gravity (it should). If it sticks in the chamber it means there is not enough headspace to guarantee reliable cycling in a semi auto.
Your other guns will all have their unique headspacing so not unusual that reloads work in one gun, but not another. Some chambers are tighter than others but all can still be in spec.
