A few years back (maybe four) I bought a pre-64 Model 70 in .300 H&H which some idiot had chrome plated! Cost $550. One trip to the chrome plating shop to have it stripped and then to the bluing tank: voila: a new appearing rifle with a new barrel in .416 Remington Magnum.

PS: Douglas will duplicate the contour of a pre-64 barrel in any caliber you might want. Just send the old barrel to copy.
