Steyr M95 bore diameter.

Your Gew-88 bore information is not correct . Your posting of that is the exact example of what I was talking about . The German military NEVER used a .307 -.318 bore . That is a civilian bore size . The Gew-88 bores sizes were as follows : 1889- .3138 - .3208 [ rifling was too shallow , wear was a problem ] ,,,,,,, 1890- .3108 - .3208 [ rifling made deeper by making bore hole smaller ] ,,,,, 1895 1/2 .3108 - .3238 [ the final military bore size used through WWII ] . I own over 50 rifles of all makers and years and they all match that , as do the original German military testing documents .
