Shooting black powder in rifles and shot guns for 50 years....a bit of machine cutting oil in water or just plain tap water is all I've ever used....never remove barrels from the stock on rifles...sometimes do with the double shot gun.
Everyone has their own preference...clean is clean. good idea to run an oil patch down the next day and you should be fine.
