I think you can't go wrong with ANY of the major reputable barrel mfg's out there, like Krieger, Douglas, Bartlein, Brux, Obermeyer, Rock Creek, Shilen, Hart, or anyone like that who has been in this game for years and has an excellent reputation. I was generalizing names, my appologies if I left any other good mfg's out of the list, it was not intentional.
My smith once told me, "Well, I can sell you whatever blank you want depending on how big your wallet is...But the truth is, in my years of experience, it's not in who makes your barrel blank....It's who builds your gun that determines how accurate it's gonna be."
And so far, he's been right. He's rebarreled actions of mine with old take-off Remington barrels he had sitting in a 55-gallon drum in his shop that he just gave me, and he trued everything up, and that rifle was shooting 1-hole groups @ 100 yards. Which leads me to believe that when you're as good as he is, it doesn't matter who made your barrel blank, but how good the smith is that does the work, and how well he knows his equipment.
