That's a pretty bold statement, considering the competition. Still, odds are that you'll be satisfied with whatever you get, if you stick with those brands with a reputation for quality. Krieger, Brux, Rock, Bartlein, etc.
If you're interested in a Bartlein, I do believe that the guy that owns Grizzly Tools is a shooting enthusiast and he sells their barrels on his website. The last time I checked it out, he had a pretty good selection. I think it's Grizzly.com
As for the Pac Nor barrels, those are worth consideration too. I've never used one on a bolt gun, but their barrels used by Noveske do shoot very well.
Since you're going the route of getting a custom barrel, I'd also give some thought to the chamber cut. I don't know a whole lot about reamers, but I am fortunate to have a world class builder near me. When he puts something together for me, I just tell him what ammo it is that I prefer and he cuts the chamber to accommodate it. I had my latest cut for a 175gr SMK in .308, so all I have to do is load to the standard 2.8" OAL spec and it puts the bullet touching the lands.
