There's not much to tweak. The Ejector has nothing to do with case length/OAL loaded round length in feeding.
It will do it's job on any case length chambered within specs for the 92 action.
The one exception is as stated above....A loaded round that is too long for the open action to extract far enough so that the nose of the bullet clears the chamber
Wether the rifle will FEED short OAL or slightly longer OAL cartridges is in the feed guides, cartridge stop & often the bullet shape,,not the ejector.
