I used a 6mmAR case (6mm Grendel) to have my reamer made by JGS. The reamer was made with no throat, I ordered a separate throating reamer to get the throat exactly where I wanted. I went with a 1-8 Bartlein barrel and ended up using 90 gr. Berger bullets. The set up is plenty accurate out to the furthest I have shot it, 300 yds. If I were doing it again I think I would go with a 13.5 twist and use lighter bullets. While very accurate I don't think the 90 gr bullets are a great advantage at shorter ranges, other similar rifles I have that are faster like my Vartarg seem to do better. I believe part of the reason is they spend less time bucking the wind.
