It may be a "budget" build but it looks very nice. I am looking at doing that with a M700 .270 in my safe when I finish researching cartridge possibilities. I have a B&C Sendero contour stock I picked up for $100.00.
I am thinking right now about the Wea. 6.5 RPM, more likely than a PRC because I think it will come near to the .264WM.
