Yes. Most new firearms have some sharp edges, especially inside the magazine feed lips. However, when you shoot the weapon, the pressures inside the case tend to force it against the chamber wall hard enough to iron-out any imperfections left from the feeding/chambering operations. You will still see scratches on the rim from the extractor whether the round was fired or ejected unfired, but they will differ slightly.
