My wife's rifle is having trouble ejecting brass. Sometimes it flings the brass out and sometimes when gets to the point where it is about to fling the brass and then the brass just kind of fumbles and stays in the action of the rifle (not in the barrel chamber so I can remove it by hand). This was sent to Savage 5 months ago for other issues. The extractor was one of the things they said they fixed (even though it was fine back then). I fear they did something wrong to it. Thoughts?
