A lube that has never failed me and have been using it since the late 80s Hoppes #9 & STP Oil Treatment @ ratio 1:1. Impregnate a sponge and put it in a gal ziplock work your cases around or you can do manual roll each one on the sponge.
And come on it has the smell of Hoppes #9 what's not to luv about that for any gun aficionado!?!
