308 Win.

This is the sporting version of 7,62x51mm NATO. It was introduced by Winchester in 1952 – only a year after the new NATO cartridge. As most other military cartridges it was expected to become popular for hunting quickly and Winchester wisely decided to make a civilian version with their name.

The purpose of the new military design was to make a more compact cartridge with a quicker cycle rate than the .30-06, and enabling a soldier to carry more rounds. It also has excellent accuracy potential and is favored by many target shooters. As the .308 Winchester fits into short bolt actions and delivers almost the same energy as the .30-06 with medium weight bullets it has become one of the most popular cartridges in the world.

The case capacity is not suited to bullets much heavier than 180 grains, however, and accordingly some hunters finds it too light for the largest species like the big bears. It is important to know that the .308 Winchester is not entirely identical to the 7,62 NATO in all dimensions due to differences in tolerances, and some rifle chambers cannot handle military ammunition.

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.
