I have the 6.8 in an AR, and the Grendel in a bolt rifle. My Bison Armory barreled 6.8 SPC is more accurate by far than the Grendel in Howa Mini. Having said that, I shoot the Grendel more because I prefer hunting with a bolt rfile.
What bolt rifle do you have? Does it come in left hand? I've shot my neighbor's AR in 6.5 Grendel, it is impressive on tough hogs, good to 300+ yards with 120 grain bullets, and best of all low on recoil. I need a LH bolt gun for my grand daughter. After she made a perfect double lung shot with a .223 on a 189 pound 8 point this year the buck made a good 100 yard run and didn't lose a drop of blood on the ground. She is decisively left hand and left eye dominant.
