The .277 Wolverine has shown near-comparable performance to the 6.8 SPC with 110 gr (7.13 g) bullets, achieving similar muzzle velocities of 2,500 fps (762 m/s) vs. 2,700 fps (823 m/s). The smaller case of the .277 Wolverine (compared to the 6.8 SPC) is more efficient and has less recoil due to its smaller propellant load.

Special Ops usage claim - can't find any reference.
