Lv2hunt,
Dimensionally, I would say it would be possible but the PF Win 70 is in the same boat as the Savage receivers. While they are dimensionally similiar to the Rem 700, they have not been tested by chambering in this size of a round to the extent of the Rem 700.
As such, I would have to recommend against it for one of my customers if I were asked this question. In the conventional receivers, I only recommend the Rem 700, Wby MkV, the large Sako and some of the CZ receivers for this chambering.
