I have read, and been told, that the chamber and leade were the only things opened up so as not to cause overpressure, but that the barrel diameter was kept the same.

correct,,,, your barrel specs may well be for the s,american military.
the barrel may have an "encircled "z" " on the barrel (under the jacket ).
the czechs made them and were close to .316 dia.
