From people who have pulled the 100 grain FMJ and replaced with a quality projectile like the 100 grain A-Max or ELD-M the major culprit is the bimetal jacketed bullet. The 100 grain FMJ uses a steel jacket with a copper wash or thin coating. Most Wolf/Barnual bullets measure .262. Whether the small diameter is used so the steel jacket can easily swage to the rifling or because of loose tolerance in Russia I can't say.
Forum members have pulled the bullets, dumped the powder then re-measured to consistent weight while using a quality bullet and obtained a little better accuracy. The steel case seems to be adequate for accuracy and best results will probably be obtained by replacing the Russian bullet and powder and replacing with commonly available powder and bullets.
