As long as your method is getting them clean then I think that works. More barrel are ruined by improper cleaning methods than from shooting if the truth were known. I like my barrels clean but I sure don’t over clean them. I clean after ever match, that can be as few as 40 or 50 rounds or if I am shooting a F-Class match it usually is 80 rounds.
There is one product that is a must for cleaning and that is a good fitting “Bore Guide”. Also you must be careful of the Crown and not let you rod or jag drag going through the muzzle end.
