Norma Brass offers a lasting life, many reloads and accuracy even after multiple rounds as it is crafted of top grade raw materials at the narrowest tolerances. The case neck is heated and allowed to cool slowly to remove internal stress and toughen it. This is called annealing, a process which makes it softer. This also prevents gas leaks and facilitates the holding of the bullet firmly for at least a decade without cracking. In addition to that, the brass around the primer pocket of the Norma Brass for sale is firm and further down the case body the hardness is enhanced to prevent stretching.
