Some of the Norma brass I received lately had the smaller hole and some had 'regular' sized holes. Even with my eyes I can see the difference. The smaller ones get tossed into the recycling bucket and the larger one go in the press. The cases I've inspected with the smaller hole, that have gone through the press, have a flare into the primer pocket. I'm not willing to bet that it won't affect how the primer works, so I toss them.
