I have several Dewey rods and like them, but I know folks that don't care for them. They feel there is a danger that particles could imbed in the coating and end up scratching the barrel. Some of those guys swear by solid stainless rods. You'd think the stainless could damage the barrel, but they feel the stainless won't hold imbeded particles like brass or coated rods will. They also won't use a cleaing rod without using a bore guide as well.
