Norma 300 WSM Cases (50)

Description

300 WSM

The .300 Winchester Short Magnum is a 7.62mm short action magnum cartridge with considerable effect.

It is very similar to the regular .300 Winchester Magnum in terms of ballistics, but takes advantage of the short action design which allows more powder to sit closer to the flash hole.

When the primer ignites, it allows a more uniform burn which in turn translates into more efficient use of energy.

A 300 WSM can therefore achieve the same ballistics with less powder.

Norma 300 Winchester Short Magnum cases take the Large Rifle Primer.

Norma Brass

Norma cases are made of the best possible raw materials with the narrowest tolerances, and they deliver accuracy round after round. Superior quality ensures a long life, and many reloads.

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.
