I'm also looking at this gun for hogs and deer, mostly hog as because where I am they are a large problem.
Go with a 1:7 twist, and 62 grain Barnes TSX. This is what I'm using with my VTAC. I shot a pig last weekend @100 yards, and immediately stopped it in it's tracks. If you want 200+ plus yards in an AR platform I'd suggest a 6.8 (my next move).
