I am still stuck in the old world but it really works for me whether I am shooting T7 or BH. BH is primarily a engineered smokeless powder but to qualify to be considered a sub it has to have Sulphur and Potassium added into the formula. Because of those two additives I still use old fashioned Blue Windex to wipe, clear and neutralize their effects after that I am really after the BH residue using Birchwood Casey 2-in-1 Bore Cleaner, an awesome cleaner lubricator.
This pic shows my bore cleaning method...
Works really well for me - quick - simple - easy!
Again just my method others will have completely different thoughts. Eventually you will settle on something that works for you,
