I have been down this road for the last 18 months. All 6.5 data starts with N160 but it is too slow. Modern rifles with short barrels need faster powders. Having been through N150, IMR 4350, Rl19, ramshot Hunter to name a few the best by far is RL17 (or Elko 17). This will give you good velocities, 100% powder burn and more importantly is available!!
in my tikka T3 the combination of Rl17 and 120gr,123gr,129gr and 140gr all work. Wish I had tried this first as mike Norris suggested!
