The diameter("at the breech face")of .470 is too small for the 9.3x72R S&S, but will work with the 9.3x74R. The length is also a little long for the Sauer, but chambers are often longer than the case. The "bore"( I guess you mean groove)diameter of .367" is a couple thousandths over German dimensions, but they must be new, likely American, barrels.
