"Norma's brass is not only good, it's exceptional."*
*Quote from an American ammunition producer.
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.
Case neck is annealed .Annealing makes the brass softer around the neck, which can greatly
extends the life of the brass.Think of a wire hanger … if you bend it
back and forth enough times it will break. Brass is the same way, in
that the more you “work it” (like bending the hanger), the sooner it
will break. The annealing process essentially softens the brass in the
area that you will work it the most, around the shoulder and the neck.
This is also 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.
They Also drill the flashholes on their brass instead of punching them.
Almost all other brass manufacturers punch their flashholes, which can
cause inconsistency and require that you debur the flash hole.
In a moment of insight, a former Norma production manager once stated:
“a
circuit board is a very complex product, which is easy to make, and a
cartridge of ammunition is a simple product, which is difficult to
produce.”
Nothing could be more true. A cartridge is
put together using many variables, and they have to be tuned to
perfection for each batch and each production run.
Quality
It takes skill
and experience to do this, as much as it takes superb engineering to
keep the machines holding tolerances of thousandths of a millimeter,
day in and day out. First class employees, tradition and solid know-how –
these are what make the cartridges produced in Åmotfors number one in quality and what make Norma one of the greatest names in the trade.
Quality is constantly monitored and rejects collected, are the basis for continuous improvement.
Cartridge case
The most important factor in the case production
is quality control. From start to finished case, there are continuous
inspections, 15-20 measurements in total, depending on the case. Of
finished cases, five of each 300 cases are taken out for inspection. In
addition to this, a final inspection is made where the cases are put
through a measuring device and visually inspected.
