key factor is cleaning the action and chamber of residual lubricant.
i use a nylon bore brush, Hoppes #9 and a drill motor to clean the chamber.
the nylon brush does not wear the chamber and the Hoppes cleans the lube from it, thoroughly; this insures reliable feeding, extraction of the spent cartridge case, and lessens chances of FTF from residue building up to cushion the firing pin strike.
