I have a Bison Upper that shoots the Hornady 120sst's real well. By loading my own, I can get around 1/2 inch groups at 100 yds. The Nosler 110 accubond also shoots good in this barrel. Haven't tried the Fusion 115's so cannot comment on those. FrankT can probably help you there. Haven't found any hunting round that doesn't shoot good enough groups to hunt with.
