Nearly all of my 1000 empty cases have this small ding in the side of it and a little scratch on the neck as well. Below is a pic of it, does this type of dent warrant not reloading these cases or should I not worry? If you run your finger over it you can feel the ding. I am not sure what is causing it either on my gun, but its the same place on 98% of the cases.
