The easiest way I have found.... you do not mention what kind of rifle it might be, but for me I strip the barred action down- remove the hammer and trigger if possible. If is scoped remove the scope.
Then immerse the barreled action in boiling water. Make sure the there is enough depth of water to reach above the breech plug a few inches. Let action sit in the boiling/boiled water for several minutes. Expansion of the barrel will allow water to work on the fouling residue in the threads.
While still really hot remove the barreled action and place the recoil lug in a vice - pad the lug with a heavy piece of leather or a couple thin strips of wood, tighten the vice and then with the proper tool try removing the BP.
It might take a couple of attempts but it will come..
