If you almost rip the press off the bench when pulling an expander back through, split necks, see variations in shoulder bump and seating depths its time to anneal your brass. Annealed brass will size as easily and as consistently as when it was new or at times even better than when it was new.
A real simple (crude?) way to tell? Use a pliers to slightly force the neck out of round. If it springs back its a good bet it needs annealed.
