SAAMI Accepts and Standardizes Two New Cartridges

The Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) recently announced the acceptance of two new rifle cartridges for SAAMI standardization. Since its founding in 1926—at the request of the federal government—the organization has created the industry standards that ensure safety, reliability and interchangeability of firearms, ammunition and components.

8.6 Blackout

The 8.6 Blackout—with the SAAMI abbreviated name 8.6 BLK—was introduced by Q, LLC. It was standardized with a 200-grain bullet traveling at a velocity of 2,200 fps and a maximum average pressure of 62,000 psi. The cartridge is based on the 6.5 Creedmoor, with the case shortened and neck widened to accommodate a .338-inch-diameter bullet. 

Kevin Brittingham established Dover, N.H.-based Q LLC in 2016. He brought decades of experience to the venture, having founded Advanced Armament Corporation (AAC)—a cutting-edge suppressor design and manufacturing firm—in 1994. He sold that company to Remington Arms in 2009 and consulted or worked for major manufacturers in the industry before once again striking out on his own.

.25 Weatherby Rebated Precision Magnum 

The .25 Weatherby Rebated Precision Magnum—with the SAAMI abbreviated name .25 WBY RPM—was introduced by Weatherby with a 133-grain bullet traveling at a velocity of 3,000 fps and a maximum average pressure of 65,000 psi. The cartridge is based on the .284 Win., but the case is lengthened and neck diameter reduced.

The Weatherby name is, no doubt, a familiar one among readers. It was founded in 1945 by Roy Weatherby in California. His rifles and wildcat cartridges quickly gained the attention of enthusiasts, along with an A list of Hollywood stars. The company, which celebrated its 80th anniversary last year, moved to the more Second Amendment-friendly clime of Wyoming in 2019. It remains family owned with a third generation of Weatherby at the helm.
