He worded it perfectly!1:9", while Berger states is "Minimum", it is not "Optimal", like they USED to print on the boxes, which is 1:8".
RL33, N570, Retumbo, and IMR8133 will all get you over 3000fps. Nosler brass, however, is notorious for having soft heads, and will show ejector marks early. ADG is much better, Peterson is good too, but I prefer ADG.
I would start at 79.0gr, and go up to 84.0ish, but make sure you stop when you hit pressure. Try them .020" off the lands.
