Remove the bolt from the rifle and lightly oil the ejector detent.  Get a fired cartridge brass and work the ejector back and forth.  If you slip one side under the extractor you should be able to the use extractor as a pivot.  When it seems loose and moving well..try insterting it in the rifle and see if it works.....I bet you just have a sticking ejector.

The other possibility is there is a little dirt or brass stuck under the extractor...check closely.

Good Luck...
