THe B.Berryare supposed to be a ton more accurate then the TC barrels but they are a ton more $. In hunting situations the TC barrels I have are plenty accurate enough. I can get 1" groups at 100yrds using my reloads but I had to work the loads a little more then with most guns I have.
If you are wanting a caliber different then what TC makes.
www.foxridgeoutfitters.com makes custom barrels with a ton more selection of calibers and lengths and cost about the same price as the TC barrels. I had a 18" 25-06 purchased from them that shot 1" groups at 100yrds.
IF you search\read posts here on the barrels youll notice some are pretty happy with the performance of the factory barrels and some had real bad luck withthem.
