Description
Norma 6.5 x 54 Mann Brass Cases Bag of 20
Norma products are known worldwide for high quality. Cartridge cases are an important factor in this reputation. Superior quality ensures long life and many reload. Norma cases are made of the best possible raw materials and to the tightest tolerances; they deliver accuracy round after round.
The case neck is annealed to make it 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, the risk of cracking increases. Around the primer pocket, the brass should be firm. Here, the hardness is nearly twice that of around the case neck.
The structure of the material reveals the hardness. During processing, the large, soft grains are broken down into smaller ones, which makes for a harder material. After the case undergoes an annealing process, the smaller grain structure increases in size, causing the hardness to decrease.
