I have several hundred once-fired 223 casings that I'd like to reload. I may also sell some to a few friends. Almost all of them have little dents in them. Some appear in the same location on dozens of casings leading me to believe that the gun that fired them was doing it. Is there a standard (Maybe from SAAMI) that says what type of dent is acceptable and what tells you to scrap the casing? I guess pictures would help... I'll see what I can do.
