I have a new Christiansen arms ridgeline in 280 ackley on it's way. I have the Nosler and Hornady manuals here but want to reach out and see what others are having success with. I plan on trying 160 grn. accubonds and 162 eld-x. I have H4831SC, RL26 and a bit of h1000 on hand but may pick up some rl22.
