Would you use them ?

Think about this ... I am sure that the time between the production of most old SxSs and the birth of collector associations and forums on the internet, bringing these concerns to light, most of the guns we get our hands on today were shot with any shotshells that were available at the time, maybe 100s, 1000s of times without even thinking of chamber length or age of the gun. If someone bought an old Fox in 1982, for example, they would simply go to the gun store in their neighborhood or K-Mart and buy any shotshell they wanted for what they were going to hunt.

Todd's comment about tapering the junction from the forcing cone to the bore got me thinking. Tapering the junction from the forcing cone to the bore is actually "lengthening the forcing cone". By the way, how much encroachment into the forcing cone is experienced in the first 1/4 inch of the forcing cone? I would rather have the extra metal than 150 psi less pressure.

Yes. "Lengthening the forcing cones" is what the procedure is called.
The gun is a 6 lb 5 oz 12 gauge, with 30" bbls, that came with 2 1/2" chambers.
Lengthening the forcing cones lowers the pressure, without weakening the chamber area.
