ejector?
Dear MikeTBC:
Is it not pulling cases out of the chamber, or, is it not throwing them out of the action? If it's the former you chamber could be rough or slightly rusted or your extractor broken; if it's the latter your spring loaded ejector in the bolt-head could also be broken, but most likely rusted.
I'd take the bolt out and see if the extractor and the ejector are AOK.
Hope that helps.
