In the absence of the rifling..or with a different charge in the round, or with even the slightest deformation between two otherwise identical rounds...you don't get similar rotation. Last I checked, planet sized rifled barrels with standard charges and standard sized and shaped planet projectiles are rare out there in space.
Is that your final answer or do you want to go back to your first example of "toilets?"
The issue isn't about "rifling", but rather rotation. Rifling determines speed while proving stabilization. Change the rifle, the round, or both, and it's still not going to change the orientation of the bullet's rotation.
We've already concluded that the imperfections/oddities could account for some of the effects in consideration of planets. See above.
