Maybe this can make things easier. They are not in the same order as the photos but the headstamps and other markings are listed. If I don't have anything in the block, I don't know what goes there. The case height may not be perfect, I'm using an old wooden ruler. I'm going to start looking them up by markings. I suspect the dummy rounds are mostly US and browningautorifle believes the red one is Norwegian.
