Uhh, actually I DO use a universal de-capper die on all my pistol brass before cleaning them so the primer pockets get cleaned.
With my Coax I can do about 30 rounds a minute once I get the motions down, takes about 10 minutes to reach that rate of speed but 500 cases goes by in about 20 minutes or so. What takes the time is I'm still using a vibrating brass cleaner, so it takes hours in the Walnut to clean the cases; then switch to corncob for more hours if I really want them shiny.
