Cure this by loosening the lock nut, turning the rod either up or down slightly until it's nicely centred, then reset with the lock nut. This might prevent or reduce brass scraping.

Some brands of dies (mmm Hornady?) are attrocious for off centre expander balls/decapping pins.
When I used to use those type of dies I used an old Nick Harvey trick, an O ring under the lock nut. Lock nut just snugged. There is enough slop in the thread for them to then self centre. But first I would rotate as described above to get the best centering.
