New SAAMI Cartridge/Chamber Designs and Revisions

"New" SAAMI Accepted Cartridge and Chamber Designs

Technical data and drawings for the new SAAMI accepted Cartridge and Chamber designs not yet included in ANSI/SAAMI Standards will be listed below.

For previously accepted SAAMI Cartridge and Chamber standards please refer to the cartridge and chamber drawing tab above.

Revisions to existing SAAMI Accepted Cartridge and Chamber Drawings

On very rare occasions a dimensional correction may be made to an existing cartridge/chamber design. In those rare cases the revision will initially be posted in this section until such time as the drawing is updated in the ANSI/SAAMI Standards.

A cartridge/chamber design that has been previously subject to revision will have an updated revision date on the drawing.

VIDEO or DVD - $10.00 each

Sporting Ammunition and the Firefighter
Item #250 (Video); Item #251 (DVD)
Nearly one million rounds of ammunition were subjected to ten different tests-from open burn conditions to tightly confined burn conditions-to examine what happens to sporting ammunition exposed to severe impact and fire. This video is recommended as an educational tool for fire departments and explains how firefighters face no danger from sporting ammunition in a fire when protected by standard turn-out gear.

Smokeless Powder and the Fire Service
Item #252 (Video); Item #253 (DVD)
This video emphasizes in the storage and display of smokeless powder in the retail environment and demonstrates that if appropriately packaged, smokeless powder will not explode and is less dangerous during fires than many other common retail materials. It addresses what the fire hazards are to firefighters or to supplies displayed in a retail store, and what quantity limits should municipal fire prevention ordinances place on the storage and display of smokeless powder in retail stores.


Informational Pamphlets and Firearms Safety Issues

This working draft of a Glossary of Industry terms has been compiled by SAAMI's Technical Committee to facilitate technical interchanges between members of that committee. It is not intended to provide legal definition of the terms included, and, in light of further experience, the definitions of these terms may change. It is not intended to be comprehensive since it does not cover the full range of the diversity of the sporting arms and ammunition industry's products. It is, in other words, a working draft that, it is hoped, may be useful in addressing certain technical matters frequently considered by the Technical Committee and is subject to further change and refinement.

It was the committee's decision that ONLY industry terms would be included which are unique to the firearms and ammunition industry directly. Optical terms have been omitted for the most part. Common metallurgical terms were not included because they are not unique to the industry. Where there is a common term with a usage unique to our industry, it has, however, been included.

Terms made up of two or more words are defined under the principle word: e.g., a "Frangible Bullet" is defined under "Bullet, Frangible" or a "Free Rifle Stock" is defined under "Stock, Free Rifle."

Lead Mobility

A variety of issues have been raised about potential environmental impacts of lead associated with shooting ranges, including the potential mobility of lead that may be transported from shooting ranges.

This review of scientific literature was conducted to summarize the understanding of the environmental mobility of lead in surface or ground water, sediment, and soil, and the factors controlling lead mobility.
