Why would anybody run a bare copper bullet in a bare steel bore without either lube or powder fouling?
The reason you should run a dry patch through to remove excess oil is because oil does not compress. A bullet can press the oil against the barrel bore with enough force to cause the oil to dent the inside of the barrel. I have seen bore scope pictures of bores that were dented by oil.
