With 17 percent more case capacity than the 5.56 and a bullet almost twice as heavy and five calibers larger delivering 78 percent more energy at 100 yards, the 6.8mm Rem. SPC was what the military was looking for. Lots of smack at close combat ranges combined with improved 500-meter accuracy and lethality.
Sounds like a decent deer cartridge, doesn't it? Remington thinks so.
Until this year, the 6.8mm Rem. SPC has been loaded only with a 115-grain FMJ, BTHP, or Sierra MatchKing at a velocity of 2,800 feet per second. Now the 6.8mm SPC has been mated with Remington's premier game bullet, a 115-grain bonded Core-Lokt Ultra at 2,775 fps.
Remington likes to compare the ballistics of the 6.8mm SPC with those of that time-proven deer slayer, the .30-30 firing a 150-grain bullet. Accordingly, the 6.8mm Rem. SPC produces 23 percent more energy at 100 yards, 36 percent more at 200 yards, and at 300 yards, the 6.8mm SPC still retains 1,072 ft-lbs of energy compared to the .30-30's miserly 565 ft-lbs. The 6.8mm SPC is 4" flatter at 200 yards than the .30-30, and in rifles of identical weight, the recoil of the 6.8mm SPC is 30 percent less.
