The .277 Fury or 6.8×51mm Common Cartridge, [4] [5] (designated as the .277 SIG Fury by SAAMI [1]) is a centerfire rimless bottlenecked rifle cartridge announced by SIG Sauer in late 2019. [2] Its hybrid three-piece cartridge case has a steel case head and brass body connected by an aluminum locking washer to support the high chamber pressure ...
The new cartridge is designated as 6.8 × 51 Common, known in the commercial market as the .277 Fury. [31] The bullet size of the 6.8 × 51mm is virtually identical to the bullet of the 7mm-08 Remington. The difference in diameter is less than 1/128 of an inch (0.2 mm), or approximately the thickness of two human hairs. [32]
The resulting COAL of 2.300" is only 1.02 mm longer than the maximum COAL for chambering a cartridge in the smaller AR-15; however, the 45 Raptor chamber pressure is allowed to be as high as 62,000 PSI. This means that the stronger AR-10 receiver and bolt carrier group is needed for shooting this cartridge.
Within firearms, chamber pressure is the pressure exerted by a cartridge case's outside walls on the inside of a firearm's chamber when the cartridge is fired. The SI unit for chamber pressure is the megapascal (MPa), while the American SAAMI uses the pound per square inch (psi, symbol lbf/in 2) and the European CIP uses bar (1 bar is equal to 0.1 MPa).
The new 7-mm .277 Fury round will be deployed both in an infantry battle rifle as well as in a dedicated machine gun and exemplifies the requirement of the much higher chamber pressure, 80-90,000 PSI Vs 55-60,000 PSI in the older ammunition required to attain the demanded ballistic performance with a 7-mm bullet in both weapon systems.

The 6.8mm Remington Special Purpose Cartridge (6.8 SPC, 6.8 SPC II or 6.8×43mm) is a rimless bottlenecked intermediate rifle cartridge that was developed by Remington Arms in collaboration with members of the U.S. Army Marksmanship Unit and United States Special Operations Command [6] to possibly replace the 5.56 NATO cartridge in short barreled rifles (SBR) and carbines.
