I received a new shipment of mixed head stamp 223 brass. I went to resize a couple of them and the die is leaving scratches on the neck as you can see in the picture. I pulled the die apart and thoroughly cleaned it thinking it may be dirt but that did not solve the issue. Anyone have any idea what is going on? It is an RCBS die.
