I am thinking about a 6ARC. I will be going to TX at the end of the month to hunt hogs but my choice has been the 6.8 spc. Definitely not a long range gun but I have killed several pigs at over 250 yards with it at night using thermal. I know you didn't ask about the 6.8 but just wanted to comment.
Having used both the 6mm AR and the 6.8 SPC on hogs for a while, I would choose the 6.8 SPC. However, I'd also have to say that almost all of my shots were usually right at 100 yards or less with both, and also I was using the 90-grain Accubond in the 6mm AR and a 120-grain SST in the 6.8 PC...so it's really kind of apples and oranges. Maybe with more similar bullets I'd have said the opposite.
