Is .277 SIG FURY the same as 6.8x51 NATO?
.277 SIG FURY and 6.8x51mm are closely related, but the names should not automatically be treated as interchangeable ammunition specifications. .277 SIG FURY is SIG Sauer's commercial cartridge, while 6.8x51mm is associated with the military's newer cartridge family. Ammunition specifications, pressure, case construction, and firearm ratings can differ. Always use ammunition specifically approved by the rifle manufacturer rather than assuming every .277 SIG FURY or 6.8x51 load is appropriate for a particular firearm.
