Would not the Mannlicher clip fed rifles be more of a controlled feed system, like the Steyr 95 and the Carcano? These have been known to break extractors when single loaded. The Lee Enfield as stated earlier with a magazine cutoff is a push feed. I saw a fellow once get off 25 rounds in a mad minute by using the cutoff and simply tossing a cartridge in the breech and cycling the action.
