Maybe one for Shed tuner this. As you know, some guns have long transfer ports and a large volume. I was wondering if you could have any success sleeving down a Cadet or Major port or is a case of if it is so long that you cannot get a hole small enough to work efficiently?
A similar thing with Webley pistols. (I know you had a play with that rough Premier Mk2 years ago).
I've found with the Hurricane/ Tempest that if the transfer port screw is a fraction too long it can drop power.
I've wonder sometimes if you made a longer barrel a later Webley pistol if you could reduce the breech seal and housing by half the thickness.
