Description Norma Brass Norma cases are made of the best possible raw materials with the narrowest tolerances, and they deliver accuracy round after round. Superior quality ensures a long life, and many reloads. The case neck is annealed to become softer. This prevents gas leaks and enables the case to hold the bullet firmly for at least 10 years without cracking as a result of aging material. Further down on the case body, the hardness increases to avoid unnecessary stretching. If it is too hard, it would bring the risk of cracks. Furthest down, around the primer pocket, the brass should be firm. Here, the hardness is nearly twice that of around the neck.
