Norma products are known worldwide for their superior quality which ensures long life and many refills.
Norma cases are made from the best possible raw materials and to the tightest tolerances and provide accuracy round after round.
The case neck is annealed to become softer, this prevents gas leaks and allows the case to hold the bullet securely for at least 10 years without cracking due to aging of the material.
Further down the case, the hardness increases to avoid unnecessary stretching, if it is too hard, it carries the risk of cracking, around the primer pocket, the brass should be solid, here, the hardness is almost double that around the neck.
The structure of the material reveals the hardness, during processing large, soft grains are broken down into smaller grains, which makes the material harder.
During annealing, small grains become larger and hardness decreases.
