NORMA Bossoli 6.5x52 Carcano #20265351 (100pz)

Norma products are known worldwide for their high quality. The cartridge cases are an important factor in this reputation. The superior quality guarantees long durability and many reloads. Norma cases are made with the best possible raw materials and the tightest tolerances, providing 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 material aging. Further down the case, hardness increases to avoid unnecessary stretching. If it is too hard, it carries the risk of cracks. Further down, around the primer pocket, the brass should be solid. Here, the hardness is almost twice that around the neck. The material structure reveals the hardness. During processing, large and soft grains are broken down into smaller grains, which makes the material harder. During annealing, the small grains become larger and hardness decreases.
