This was exactly my experience with a Campag Centaur BB (in a brand new bare metal frame). I removed and refitted a couple of times but couldn't see any reason for it binding other than poor tolerances. The manual even says something about backing off the torque and using loctite if it binds which I felt was a poor solution.
Even at the reduced setting it was still too tight IMO.
Sent it back to the supplier in the end who claimed there was nothing wrong with it.
I then read about a couple of other people who had exactly the same issue!
Switched to a Sugino and it was perfect.
Can you return the BB you have? at least to see if another of the same model behaves the same...
Might be campag's tooling on that line is a bit worn so its not making full depth threads in the BB all the way along = gets super tight to fit, could result in cracking the BB shell if forced in there (unlikely)
