Most shooters have heard the "name" SAAMI
Ever wonder what makes today's firearms and ammunition safe and consistent?
This article was posted by a member on another forum, it is very interesting and not at all just for reloading.
It is the history of SAAMI and the standards, as well as compared to the CIP (European standard which is regulated by Government), SAAMI is NOT, it is voluntary.
Also interesting is that SAAMI was one of the original organizations for protection of Wildlife way back in 1928!
It's a very interesting article if one takes the time to read it.
