1. Reputation for High Quality: Norma products, including their cartridge cases, are known worldwide for their high quality. This reputation is built on delivering superior products.
2. Long Life and Reloads: The superior quality of Norma cases ensures a long life and allows for multiple reloads, indicating durability and reliability.
3. Best Possible Raw Materials and Tight Tolerances: Norma cases are made from the best possible raw materials with the tightest tolerances, emphasizing the use of high-quality components and precision in manufacturing.
4. Annealed Case Neck: The case neck is annealed to achieve softness. This process prevents gas leaks and ensures the case holds the bullet firmly for at least 10 years without cracking due to aging material.
5. Varied Hardness Across the Case: The hardness of the brass varies across different parts of the case. It increases down the case body to prevent unnecessary stretching. The brass around the primer pocket is notably firm, with a hardness nearly twice that of around the case neck.
6. Grain Structure Impact: The structure of the material plays a role in determining hardness. During processing, large, soft grains are broken down into smaller ones, resulting in a harder material. The annealing process reverses this, increasing grain size and decreasing hardness.

Norma’s meticulous manufacturing processes, including annealing and maintaining specific hardness levels in different parts of the case, highlight their commitment to providing accurate and reliable cartridge cases for reloaders. These features make Norma Brass in 6MM Norma BR a preferred choice for those seeking precision and longevity in their ammunition.
