usually, when i decap a bunch (roughly 300-500) of shells i pull the press from the bench and clean the ram and re-lube it. i have the ram coated with lyman moly bullet lube, and add a couple of drops of mobil 1 w/ stp mixed in. the results is a SUPER SMOOTH opperating press. the only problem with the stp is it sucks the dirt to the ram. but it is easy enough to clean. just one of those things.
