I usually use Shilen Barrels or ones from The Montana Rifleman. Both these companies offer barrels that will shoot one hole groups with proper bedding and the correct loads. In general I have found that supporting the chamber area and leaving the rest of the barrel free floating works best.
Both of these companies offer pre threaded and chambered barrels for many actions, however these are chambered long so you need a lathe to head space them. If you do not have a lathe, look into the Shilen barrels offered by Brownells. These are Match grade and short chambered so all you need to head space them is a chamber finishing reamer. You can get reamers trhough Brownells or you can rent them from a place like White Rock Tool.
