I have the identical rifle, Mine has really liked the Lapua Sencar 155's over varget, though I had decent groups with 168 Amax and Varget. I am gonna run with the 155's though, I can push them up to about 2900 without pressure and the load is so accurate I can tell when I dont do something right. If I am shooting right it will put 5 in the .3's at 100yds. YMMV though. Mine shot most everything decent, around 1MOA or so but im always trying to get that extra out of it, I will be adding a brake and a SSS trigger to mine shortly, hopefully that makes it easier to shoot for me.
