The .277 Fury or 6.8×51mm, (designated as the .277 SIG FURY by the SAAMI) is a centerfire rimless bottlenecked rifle cartridge that was first announced by SIG Sauer in late 2019. It is a hybrid three-piece cartridge and has a steel case head and brass body, which are connected by a locking washer to support its high max chamber pressure of 80,000 psi , which significantly exceeds even rounds with notoriously high pressures.

Military Contract & Adoption

On April 19th 2022, the United States Army announced that it had selected SIG Sauer to build the new XM5 Rifle to (partly) replace the existing standard M4 carbine, as well as the XM250 Automatic Rifle to replace the already standard M249 SAW. Along with the and that it had selected the company's .277 FURY cartridge, utilizing government provided projectiles and vendor-designed cartridges as ammunition for the new weapon systems. The XM5 and XM250 were designed to fire the 6.8×51mm SIG Fury cartridge based on concerns that improvements in body armor would diminish the effectiveness of the current 5.56×45mm NATO cartridge used in the M4 carbine and M249 SAW. A newer, more effective cartridge would help increase their lethality as well as their effective range when compared to common battlefield rounds such as the 5.56×45mm NATO and 7.62×51mm NATO.
