Something else to check ....... see if your chambers are rough from corrosion or shell contaminant buildup. When I shot high volume in Argentina my chambers would get plastic residue built up to the point that it would make for weak, even no, ejection. A few brisk passes with an oversized chamber brush would restore perfect ejection.
Fortunately this is one is in pretty dang good shape. Bores and chambers are free of any rust or pitting. Has a good amount of the case hardening remaining and the only thing I can find wrong aside from the ejectors is the original owners name engraved on the trigger guard
