So I have about 13,000 cases through my Lee 223 die set. I take the full length size die apart and clean the decapper/expander every 1000 or so cases to make sure it is clean and remove any gunk that might collect at the top of the expander. Lately I have noticed several gauges running up from the top of the expander towards the top of the rod. I doubt they affect anything but should this rod be getting gouged up? Especially with so little use?
