Grooves for 6BR barrel?

[shadowdrak]

I'm looking to get a new barrel and looking to switch over to the 6BR round. I'm looking at getting a Krieger SS 28" finished length, with 1:8 twist, and a .272 no-neck turn. I'm looking to shoot 87g. V-max to 105g. VLD. What would be a good groove choice to ge for this barrel? It's mostly going to be varmint rig. Thanks

The only thing I can honestly say about three groove barrels is they seem to break in easier and clean easier. They aren't any more or less accurate than a barrel with more grooves.
