Recently I was given a swag of deprimed and cleaned 5.56 cases for range shooting. Although they were of different makes and years, the following caught my eye:
(1) W.C.C O 3 standard WCC layout with large dots centralised either side of the middle “C”.
(2) Normal five position layout - W C C O 5
(3) Nato symbol at 12 with WCC 05
Questions are: Why the dots on (1) and reason for the two headstamps for the one year i.e. 2005.
I am presuming that (1) is for a manufacturing process, (2) is for normal usage and (3) for Nato usage. Answers?
