Norma Cases 300 HH QTY 50
Introduced as late as 1963 this cartridge was soon to become the most popular in the line of .300 magnums. Unlike the predecessors .458, .264 and .338 Winchester Magnums it has a longer case and a rather short neck (.264”) in order to increase the case capacity. As a rule of thumb the neck of a cartridge should be equal to the caliber or preferably a little longer, but experience has shown that the .300 Win. Mag. has not really suffered in this respect. It can still be used in a standard-length bolt action but this means that the heavier bullets must be seated rather deep and hereby occupy some of the powder space. Like the other .300 magnums it is at its best for hunting larger species like moose or elk at long range. The recoil is heavy, but most shooters will be able to handle it after some practice and handloads with lighter bullets are a good choice for this purpose.
Norma Brass
Norma Brass is the gold-standard of cartridge cases.
Norma products are known worldwide for high quality. Cartridge cases are an important factor in this reputation. Superior quality ensures a long life and many reloads. Norma cases are made of the best possible raw materials with the narrowest tolerances, and they deliver accuracy round after round.
The case neck is annealed to become 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, it would bring the risk of cracks.
Furthest down, around the primer pocket, the brass should be firm. Here, the hardness is nearly twice that of around the 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. At the annealing, small grains become bigger and the hardness decreases.
