I am preparing some new blue box brass 6.5x284, the primer pocket seems to have a cup swagged in place. Is this normal? This is my first batch of 6.5x284 Lapua brass, I was using Norma. I have not seen this before, on any brass, and am not quite sure what to think. If ya need a picture pm me an email address, my so called smart phone won't post pics here.
