The pull cords break away from the the main part. Not the firwt time this has been discussed amongst gunsmiths.

I understand that the pull cord breaks away from the main part. However, the main part is long enough to pull it out by the end part not by the front part where the break occurs.
My bore snake rope or main part(not the pull string) is just over 27 inches long. So if the pull string breaks away even at the end of the barrel, there is still rope sticking out from the other side of the barrel to pull it back out.
