.277 FURY

The .277 FURY, also known as the .277 SIG FURY,[lower-alpha 1] is a centerfire rifle cartridge announced by SIG Sauer in late 2019.[1] It utilizes a hybrid case of brass and steel to support a chamber pressure of 80,000 psi (551.6 MPa).[1] The high chamber pressure enables a projectile speed of 3,000 feet per second (914 m/s) from a 16-inch (406 mm) barrel.[2]

Background

The cartridge was designed by SIG Sauer for the United States Army’s next generation squad weapons program,[3] officially known as the Next Generation Squad Weapon-Rifle (NGSW-R).[1] The cartridge was announced for non-military usage along with the SIG Sauer CROSS—a bolt-action, magazine-fed rifle—in December 2019.[4]

Specifications

The cartridge uses a case that is the same length and diameter as the .308 Winchester.[2] Each cartridge consists of a steel base coupled to a brass body via a locking washer.[5][6] Bullets are either 135 grains (8.7 g) "match grade" or 140 grains (9.1 g) "hunter tipped".[6]

Performance

SIG Sauer claims that the cartridge has performance superior to the 6.5mm Creedmoor, exhibiting 6 to 9 feet (1.8 to 2.7 m) less bullet drop at 1,000 yards (914 m), while delivering 20–25% greater energy.[6]
