Took my Stevens 301 20 ga out to the dove fields this morning and it would not eject about one time out of 7 or 8 shots. Had to push the empty shell out with a make shift ramrod. The shell not picked up by the ejector...sitting completely in chamber and could not be gotten out only by pushing out from end of barrel. No problem ejection a shell that has not been fired. Bought it new this spring and never turkey hunted with it. Only shot a few 3' shells with it getting it on target. Got home and cleaned it good and oiled it where ejector sits and ran several unfired shells thru it and worked perfect. What could problem be...maby it needed oiling. Anyone ever had this problem?
