NORMA Bossoli .270 Weatherby Magnum #20269127 (50pcs)

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 accuracy 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, hardness increases to prevent unnecessary stretching. If it is too hard, there is a risk of cracking. 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, making the material harder. During annealing, the small grains become larger and the hardness decreases.
