Nosler is releasing a new long range Accubond this spring and they have 3 offerings for the .284 size, a 150, 168 and 175 grain bullets and the BC looks very impressive. I hope to work up some loads using R17 and the 168 LR Accubond for mine. I'm using R17 in several calibers and the velocity and accuracy are really good.
