Nylon / plastics can be fairly abrasive. Think of ScotchBrite or BearTex pads - those are made from nylon and are the equal of steel wool. Personally, I would not use a drill with the brush.
Just swab the bore with your favorite cleaner and let is sit for 10-20 minutes. Brush the bore 10 or so strokes swab out the bore with more cleaner. Let it sit for 5-10 minutes, brush one more time and then swab out with cleaner, swab the bore dry, and then lightly oil and you should be done.
I use both Shooter's Choice + Kroil, and Gunzilla for cleaning and either will easily take out fouling. The Shooter's Choice with 20% Kroil (by volume) added to it will aid in taking out leading if you let it stay in the bore about 30-40 minutes.
