The .277 Fury or 6.8×51mm, (designated as the .277 SIG FURY by the SAAMI) is a centerfire rimless bottlenecked rifle cartridge announced by SIG Sauer in late 2019. Its hybrid three-piece cartridge case has a steel case head and brass body connected by a locking washer to support high chamber pressure of 80,000 psi
