Who makes Weatherby's carbon barrels?

[Tlwhitus]

Who is now making carbon barrels for Weatherby? Seems like they went with Proof a couple years ago. Now, I am seeing that they may be running BSF. Does anyone know for sure?

BSF.

It's even on the Weatherby website.

Is bsf the one that uses a sleeve so there's an air space between it and the barrel
