Another vote for whichever you can get. I have used primarily Bartlein but just bought two CRB barrels and had chambered, early signs are they are tack drivers as well.
I’ve gotten the following: 2 260, 3 308, 2 GT, 2 6.5, 3 223, 2 dasher, 1 bra.. all Bartlien and they all shoot really well. I’d go with a Bart barrel cut by Wade any day.
