Cheesehead,
We've talked about my Bushmaster 6.8 before, but I thought I'd let in on my last trip to the range with it. I had some factory Silver State Armory rounds loaded with the Barnes TSX. I fired a couple shots at 25 yards and it was basically one hole. I fired three shots at 100 yards and I could cover the group up with my thumb (sub MOA). It's just something you may want to consider. After the 100 yard group I put the expensive ammo away and started shooting my other reloads, none of which shot as well as the SSA barnes TSX did unfortunately.
