Have you tried Numrich <gunparts.com>? What caliber are you looking for....300Sav; .303Sav.?
Next question: You say this is a takedown barrel. Is the reason you're looking for another barrel is because it doesn't lockup tightly? There is a technique that you can do yourself that will fix this problem by peaning the threads slightly. I will steer you to the 24 hour Campfire Site...Savage Collectors where someone there can give you details on fixing the barrel. Finally, If the barrel is shot out, it can be re-sleeved so it will retain its original value. Hope I've helped!
