American Rifleman - July 2014 - 37

in SAAMI is voluntary, but essentially involves the agreement to
produce products that will safely
fit and function with other members' products. The key word
is "tolerance." The tolerances
allowed are close, but permit the
manufacturers a degree of choice
in design.
The 7.62x39 mm is an active
SAAMI cartridge. One of the several cartridge "features" defined
by SAAMI concerns chamber
pressure produced. The means by
which this property is measured
requires a brass case, which
immediately precludes steelcased ammunition.
To get Ruger's perspective, I
contacted a member of the company's service department. He was
quite familiar with your concern,
and also mentioned issues of
extractor breakage and debris
from the case coating fouling the

firing pin and gas system, and that
the ammunition is not to SAAMI
specification. Ruger's official comment regarding ammunition is,
"Only factory ammunition manufactured to U.S. Industry Standards
should be used in a Ruger firearm."
That begs the question of
why the same ammunition usually works fine in SKS and AK
firearms? (Note that neither guns
nor ammunition are produced to
SAAMI specs.) The answer goes

back to tolerance and design
features of the firearm makers.
Those rifles and their chambering
were designed for infantry use. In
such cases, accuracy is important,
but reliability is paramount. The
Ruger will deliver significantly
better accuracy and can be utterly
reliable, but it will require that the
ammunition used be constructed
with the same attention to specifications as the firearm.
