Webley and Scott tubes are quite hard so a lot of hammer work will be needed , Problem is getting between the tubes . I have never been successful in this even taking the barrels apart to attempt it .

I suppose it could be done with rollers and heat but this would be more trouble and cost that the gun is worth .

Sleeving would be the logical answer , Sleeving one tube only presents its own problems such as matching tube profiles so the ribs set correctly . Sleeving down a bore size is again possible if you can get tubes suitable in size at the back ends .This again has its own problems with forend fit and will almost certainly need a new loop , not to mention the fit of the wood to the barrel .

Converting to "double rife " you have to consider the back pressures and if the action will take it , which from my experience of W & S guns I would be very cautious about .
