Did he really. I no longer have a copy so I will take your word for it. Cardew used to tune quite a few rifles for shooters in addition to repairing/restoring antique pneumatics, Giffards etc. He charged for the work he did. Cant agree with you about ports having read his books.

The main point of my first post was to agree with the advice that whatever you do should be "undo-able"if it doesn't work out
