It's also got the shoulder pushed back some so a bit less case. But with oal limits the 6mm will be better for long range paper and steel. But for hunting the 6.5 may be the better option. I 100 percent would have went 6mm turbo or probably even the arc but the Grendel was affordable at the time and nobody made decent 100gr rounds.The 6mm arc is a necked down 6.5 grendel. For targets and steel banging the higher bc of the 108 eld makes a difference. In a hunting situation I would rather be able to shoot heavier 6.5 bullets.
Plus I've always liked the 6mm for no reason other than I like it so I always lean that way. Not sure one is better than the other unless you have very specific needs. Paper and steel 6mm arc hunting 6.5 Grendel same 100gr bullets will leave more room in case for powder. Will hit bit harder on game.
