 == Long-range Performance ==
-According to SIG Sauer, this cartridge has performance that ''exceeds'' the highly popular [[6.5 Creedmoor]]. It shows 6 to 9 feet (1.8m to 2.7m) ''less'' bullet drop at 1,000 yards (914 meters), while delivering 20–25% ''greater'' energy. This is almost certainly a result of the ''massive'' chamber pressures that they were able to achieve with the .277 SIG Fury.

+The cartridge uses a case that is the same length and diameter as the .308 Winchester. Each cartridge case consists of a stainless steel base coupled to a brass body via an aluminum locking washer. Stainless steel has a significantly higher yield strength than brass, which allows the engineers to use higher Maximum Average Pressure (MAP) levels than would be possible with traditional brass casings.

	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.
