Ray - most custom barrel manufacturers recommend something similar to what you posted. My only comment would be - why not use a combination powder/copper solvent (like Shooter's Choice) and just brush for ten strokes? Also, Shooter's Choice will leave the bore with a slight amount of oil in it. You don't want to shoot the next shot out of completely bone dry barrel - but you also don't want to ever shoot a round out of an oiled barrel. You can actually change the way a barrel air guages by firing one shot through an oiled bore. After pushing the last patch soaked with Shooter's Choice, I would recommend a dry patch before the next shot. Otherwise good information. Roskoe.
