I'm with flounder, except that I usually swab the bore with one side of an alcohol patch between shots - sometimes both sides. I never pull the breech plug except for final cleaning after the range session.

During a range session if you swab with a patch lightly moistened with 91% isopropyl alcohol you don't need to follow up with a dry patch because it evaporates quickly in the warm bore. I hunt on a squeaky clean dry bore and never pop a cap before loading.
