It depends on the barrel profile whether or not this can be achieved. Some barrels (BSA, Parker Hale, etc.) only have a narrow shoulder in front of the receiver. A parallel reinforce of 12mm or more will be fine for setting back. Polishing the chamber will solve the extraction problems (probably) but will give an oversize chamber. The photos look like the chamber is fairly generous already.

@gundoc thanks for that. I went to see the my Smith on Saturday and spoke about this we are all on the same page. He doesn't do the barrel work though but he did say, that if this doesn't work then he would cough up for a new barrel.
But the communication is all good and that is the main thing
