I acquired 5 identical rounds with this headstamp and Winchester type protected primer with cncs bullet
All 5 cartridges have identical holes in case wall.
I have not seen this type of primer on pistol cartridges.
Last photo shows same headstamp with copper primer and black primer seal and similar headstamp with brass primer except for placement of dot in 7.65
Are these factory dummy’s?
What is the story on protected primer?
