Norma products are known worldwide for their high quality. Cartridge cases are an important factor in this reputation. Superior quality ensures long durability and many reloads. Norma cases are made with the best possible raw materials and the tightest tolerances, providing precision round after round. The case neck is annealed to become softer. This prevents gas leaks and allows the case to hold the bullet firmly for at least 10 years without cracking due to material aging. Further down the case, the hardness increases to prevent unnecessary stretching. If it is too hard, it carries the risk of cracks. Lower down, around the primer pocket, the brass should be solid. Here, the hardness is almost double that around the neck. The material structure reveals the hardness. During processing, large soft grains are broken down into smaller grains, which makes the material harder. During annealing, the small grains become larger and the hardness decreases.
A good cartridge case must be able to be used multiple times before being replaced. For this reason, when stresses increase, at the moment of firing, there is no room for error. The dimensions of the cartridge case must be extremely precise with minimal tolerances. Norma cartridge cases are famous worldwide for their high quality. And this is why many well-known ammunition manufacturers use Norma cartridge cases to produce their cartridges.
