If you hung up on controlled feed/extraction with metal blade ejector I would suggest old Husqvarna sporter in cal. 9,3x62mm. It is only about 20% less powerful than the 9,5x73. Anyhow theses old HVAs can be had for kool $600 even if in very good original condition. Word of warning unlike CZ550 Mannlicher in said caliber they're light so they will kick the [bleep] out of you when the trigger is pulled.
