So the cups can wiggle in the threads before you put the BB together?
The bb shell can't be ovalised. There would be evidence of thread damage for that to happen. I doubt the OP is putting the required torque on the cups it's 30nm+ with grease on the drive side anyways.
Now let's get some useful information of the op:
1) Specific bottom bracket he's using
