I have done it both ways, cleaned to bare in my ss tumbler or leaving the carbon. On target rounds I leave the carbon, after sizing I just use some paper towel and wipe out the neck this leaves the carbon and likely just a hint of case lube. Bullet seating feels very consistent this way.
When I run cases through the ss pins the resistance seating feels slightly off case to case. That said I dont see much difference in 100 yard groups, the es does seem slightly higher on my cleaned brass but with small samples (5-10 shots) those numbers dont mean much. Sounds like a good test to run, 10 shots at 300y cleaned/non-cleaned and see what the results look like.
