This past weekend, I purchased a well cared for Ruger Red Label 12 gauge. I took it out yesterday, and shot a few shells through it just to make sure it would go "bang". After firing, when I broke open the action, the lower empty shell case shot right out of the chamber like it should. The upper barrel did not. The ejector only forced it up an inch or so. Is this a major concern, or a mere nuisance? What can I do to fix it? Should it be reffered to a gunsmith. I must confess that the loads were some cheap Winchester Dove Loads. Thanks!
