I just built the rifle and it shoots outstanding with the Berger 105(.27 moa) with a nice big node and decent velocity. I am wondering if the 109 will actually have better BCs and be able to take a tenth or two off the wind at 1000-1200? I have read what I cold find but not much with people running the GT. I have a 7.7 twist Mullerworks barrel if that makes any difference.
