Norma is known around the world for making very high quality precision components. Brass is an often overlooked, yet extremely important part of the rifle cartridge. The case neck is annealed to become softer. This mitigates gas leaks and makes for a case that will last for a very long time. Underneath the neck/shoulder the case is not annealed. This is because the much softer annealed portion of the case would stretch and not last very long. The picture below shows the different harnesses of the case. The case head and primer pocket are nearly twice as hard as the neck. At the annealing, small grains become bigger and the hardness decreases.

    Weights and trim length are pretty consistent Primer flash hole clean without burrs. There were several necks that were beat up and ragged. Id expect better for premium brass
