Sure thing!
Austrian and Hungarian (1930 and 31' respectively) 8x56mmR conversions concentrated on lengthening the chamber for the longer 8x56mmR case, using all of the original existing 8x50 barrels.
(You can use an 8x56mmR case, trim it to 50mm and it will fit right in an 8x50mmR chamber).
The bore diameter through the cartridge conversion stayed the same. A typical bore on the M.95 were oversized (generally from .329-330) needed for the extra obturation (expansion) of the flat-based RN 8x50mmR .323" (M93 O-Patrone) 244grn projectile into the rifling. In addition, smokeless or "semi-smokeless" powders during the period burned dirtier than what it does today, fouling was a bigger issue back then. With powder fouling, the larger bore diameter also allowed the rapidly expanding flat-base projectile to pass through more easily after fouling build up.
The 8x56mmR Spitzgeschoss (pointed bullet) (M30 S-Patrone) 208grn projectiles were of the boat-tail design made to .329", so only a chamber modification for the case was needed and smokeless powders by the 1930's had already vastly improved from the early stages of the 1880's predecessor of dirtier smokeless powders and was no longer a real issue.
Here's an Austrian 8x50mmR flat-based cupra-nickel RN projectile. The skirt behind the crimp would rapidly expand more than the later improved boat-tail.
