If you want consistant 1/2 moa 5-shot groups the barrel is only part of the equation. A good 'smith is essential, and he can provide good recommendations on barrels, etc. I've had very good accuracy with Hart, Lilja and Jarrett barrels, but these can be costly. But then good stainless barrels are more costly because they are more difficult to machine with a dimensionally consistant, smooth finish in the bore.
When rebarreling, consider having the front of the action trued, the bolt face trued, the bolt lugs lapped, and the action pillar bedded into the stock. These extra steps help to insure that your shooting skills will be the limiting factor on accuracy - not the rifle. Good Luck, and have fun!
