What type of rifle? I did some 'research' (beer and internet) before I fired mine, as the calibre marking is hidden underneath the base for the claw mount. The side of the barrel is stamped '7.9' but research suggest that all Brno's were made with .323 bores and both the 8x57 and 8x60 Brno's were all stamped with '7.9'.
I did read somewhere that german law prohibited the manufacture of new firearms with a .318 bore instead of .323 after a certain date (sometime before ww2) but now I cannot find the page I read it on.
If its a Brno I'm confident its a .323, but if its pre-WW1, then anyone's guess.
