The Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI), has released two new online reference tables. These resources clarify the interchangeability of certain ammunition in a specified firearm chamber, and identify the names of equivalent and historical cartridges.

SAMMI states: “These documents are important for firearm safety because they … 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 … 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”, stated Joe Bartozzi, SAAMI President/CEO.

Access both documents on the SAAMI.org website under Informational Publications and Advisories.
