I have a savage 10 action that I'm building a 308 with. It's going in an HS Precision stock. I'm using a heavy barrel Lothar Walther stainless barrel. The problem I'm having is that the barrel goes hard left when assembled. I've checked in different stocks to make sure it wasn't the stock, I've tried different recoil lugs with the same outcome and my barrel nut is a precision nut that has been checked for flatness. The only thing I can figure is that the face of the action or the action internal threads are way off. Anyone have any suggestions or experienced this before?
