The Steyr m95 is designed for a rimmed cartridge and both the old 8x50r Austrian and the 8x56r are rimmed. The Austrians went to a more heavily loaded cartridge as mentioned above in the 1930's which is when they converted most of the long rifles they had into carbines. They use an odd .329 bullet rather than the .323 that the Germans used in their 8x57 Mausers. Prvi Partisan makes ammo for the 8x56r but not the older round. A few have been converted to non-issue rounds including a .303 British so have the chamber checked as these were $99 rifles a few years ago but now worth $350-400 in good condition so a conversion no longer makes sense for these.
You will need to acquire clips for the rifle and these clips are around. When empty, they eject through the bottom and new clips go into the clip feed at the top. (These are true clips rather than magazines).
The major issue with action roughness is because you need to do a detailed disassembly including the bolt which is a pain to disassemble. The bolt is a straight pull which means that it does not have fixed lugs like the Mauser bolts but the bolt head with the locking lugs rotates within the bolt body. Any dirt, crud, dried oil, etc. will tend to make the action sluggish and the only way (aside from possible using a ultrasonic cleaner which might also have some undesirable effects) is to disassemble and thorough clean up the bolt. While you are at it, I would also thoroughly clean the insides of the clip feeding magazine. I find that Slip 2000 does a spectacular job of lubrication that smoothes this action out as well as working for other straight pulls like the the Swiss K series rifle bolts and Ross rifle bolts.
There used to be step by step pictorials for the m95 in doing that but they have seemed to vanish as did the TN Gun Parts that used to be associated with the pages. Scarlatta and Mowbray's book on military rifles and their disassembly has a detailed description of what to do with color pictures. Worth the money especially if you get more milsurps.
