LEDE 7Mm Backcountry Cartridge Drawing

The Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) recently announced the acceptance of Federal’s new 7mm Backcountry (7mm BC) rifle cartridges for SAAMI standardization. SAAMI is the organization leading the charge in promoting firearm safety by creating standards that ensure the safety, reliability, and interchangeability of firearms, ammunition, and components. SAAMI’s Technical Committee, which consists of firearm and ammunition industry experts, reviewed the 7mm Backcountry submission for about six months. The official cartridge name, maximum cartridge and minimum chamber dimensions, pressure limits, test equipment, and other characteristics are all considered and scrutinized during the process.

“We all at Federal are once again excited to have a new cartridge accepted by SAAMI,” said Federal’s vice president of product development, Jesse Whiteside. “The 7mm Backcountry, with a 170-grain bullet traveling at a velocity of 3,000 fps and a Maximum Average Pressure of 80,000 psi, passed the organization's robust review process and is now an active standard. SAAMI’s published standards for the 7mm Backcountry will help expand this ultra-fast and accurate new cartridge to be used in shorter barreled, suppressed hunting rifles across the industry.”

Federal’s 7mm Backcountry is a new high-performance hunting cartridge boosted by new, patented Peak Alloy case technology. To learn more, visit federalpremium.com. Also check out American hunter's coverage of the cartridge here, featuring an interview between America's 1st Freedom Editor in Chief Frank Miniter, and Mike Holm of The Kinetic Group. The two go in-depth on the unique features of the cartridge, the original idea behind it and the success it has already seen in the field.

SAAMI allows free access to technical data and drawings for the cartridge and chamber designs, which are posted in the Information and Specifications section of the organization’s website. All cartridge and chamber drawing documents, including the one above, are within the ANSI/SAAMI Standards and can be found on saami.org.
