If cleaning from the muzzle I use a bore guide. I have bottle neck cases I have cut the shoulder and neck from and slip the rod through the neck and that pratects the bore.
In a 30 cal I use a 270 case cut off and it will fit in the bore at the crown. This keeps the rod from rubbing on the end of the barrel.
