If you are really concerned about scratching the bore especialy the crown . I would suggest a bore snake . When it comes to my rifles I only use the cleaning rod for soaking the bore and to oil the bore if Im not planning on shooting that particular gun any time soon . All other bore cleaning is done with a bore snake . They always come out squeaky clean .
As of this date 8-18-14 at 6:42am I became a proud grandfather I guess I'm officially old
HAPPY BIRTHDAY TO HIM
