No, you might get a little brass color on the steel wool or scotchbrite but the actual dimension change would be in the hundred thousands or million's of an inch. Put it this way, if you wanted to take that steel wool and steel wool the whole neck away it would take weeks. I would think that a tumbler with abrasive polishing compound would take off more brass
Scothbrite seems to be more agressive
and leaves no oily residue like steel wool so the mica does not stick as much
Many many reloaders use steel wool on brass with no ill effects
