For immediate release | October 14, 2021

NEWTOWN, Conn. – The Sporting Arms and Ammunition Manufacturers’ Institute,®Inc., (SAAMI®), is pleased to announce that it has added two new web-based resources. These new documents help to clarify the interchangeability of certain ammunition in a specified firearm chamber, and identify the names of equivalent and historical cartridges.


These documents are important for firearm safety because they provide industry and recreational shooters the ability to identify what ammunition can be safely shot in firearms, whether it is an alternate cartridge in a specified firearm chamber or a known equivalent historical name for a cartridge.


“These important documents add to SAAMI’s technical library of firearm safety resources that provide guidance to both industry professionals and the firearm-owning community. They emphasize important safety and technical information regarding the proper matching of ammunition and firearms, and what precautions must be taken,” said Joe Bartozzi, SAAMI President and CEO.
Both documents were developed by the SAAMI Joint Technical Committee and can be found on the SAAMI website under:

The new documents are:

This document lists generally accepted alternate firearm/ammunition combinations which will generally allow for the safe firing of an alternate cartridge in a specified firearm chamber. There is also information on shotshell interchangeability and commercial vs. military standards.
