After waiting 4 months to get my new Norma 300 Win brass I am having some issues priming the brass. The primer pocket is really tight. In fact, its so tight that in order to get the primer to seat all the way in I have to really squeeze my RCBS priming tool. I did uniform all the primer pockets, however while squeezing so hard the plunger is leaving a half moon mark on the primer, is this ok? I have never had any issues with Norma brass, should I de-prime and return the brass, as the going rate is $140 per 100.
