I have 60 new Norma 22/250 brass that I am going to load. When I load I uniform the primer pocket, debur the flash hole, neck size and turn the outside neck. I use Redding Competition dies. Being that Norma brass is so uniform should I unifrom the primer pocket and debur the flash hole before the first fireing of this brass. How should I take care of my Norma brass before and after the first fireing ? I have not used Norma brass before because it is too expensive. Thank's Norman
