Chamber area on the 12 gauge is the same as the 20 - I spent this afternoon working on a stub using a 12 gauge barrel. This is my first stub and so far so good. Mine will be a 32 H&R Magnum - or maybe 327 Magnum - I'll see which way it goes when I get the stub ready to chamber. The 20 gauge was what I had handy when I took the measurement - my 12 gauge donor barrels were in my shop. Only problem with a 12 gauge barrel as a donor for the sub is it pretty thin in the chamber area so on mine I'm going to use epoxy to hold the new barrel in place rather than try to thread anything - not very experiences with my lathe either so avoiding cutting threads partly for that reason as well.
