I havea SBE that will shoot anything I put in it. It is now set up for Turkey hunting only, put a steady grip stock on it and a red dot. So now it only gets a diet of 3 1/2 inchers. But before, never had a malfunction at all. But guns are machines and some of them will break or not work without a little tweaking. May just need "broke in" ora small adjust with extractor or ejector. If it doesn't work itself out I would take it to a gunsmith.
