Quote:

The 6.8x43mm SPC was conceived by a U.S. Special Operations soldier in a quest to improve the terminal ballistics of the M4 Carbine. The U.S. Army Marksmanship Unit and others assisted the Spec Ops team heading the project. Although the main objective was increased lethality, the new cartridge would go far beyond that in terms of accuracy and performance.


After selecting the .30 Remington as the parent case--a decision that required only slight modification to the M16's bolt face--the case was shortened, given a new shoulder and blown out to maximum capacity for a new high-performance propellant. After testing a variety of bullets in 5.56mm, 6mm, 6.5mm, 7mm and 7.62mm, a bullet of 6.8mm was selected. This .270-caliber, 115-grain projectile has a ballistic coefficient of .350, offering optimum lethality and range.




It is an excellent round and ought to be ideal in the Encore pistol
