Maybe this will help some. I have a 6.5 JDJ, not the #2, and I really like it. I have had good luck with RL 15 using the 100 and 120-grain Nosler BT's and the Speer 120-grain Hot-Cor. All of the these bullets have produced 5-shot groups around 0.8" at 100 yards from the bench. Varget is a close second with the 120-grain BT. Bummer about the load data from SSK.
