The D-81TM TL Russian tank cannon is in High Tech. It's 125 mm, or 12.5 cm. And it's damage, with APFSDS, is 6dx30(2) p++. It's muzzle velocity, according to wiki, is 1700 to 1800 m/s, or better than one mps.

What is being used to justify the order of magnitude increase?

Yeah, it's errata as FenrisLoki points out, and it's in current versions of the PDF.

No. The damage in question is for one shot. (And couldn't possibly be otherwise in GURPS. DR applies per shot, so damage has to be given the same way.)
