Have you selected the bullet you are wanting to use? What range do you primarily want to focus developing your load around? I am working on the same project, and have selected the Berger 95gr Hunting VLD bullet. However, that particular bullet in my gun setting .0010 into the lands is single feed only. The Berger 95gr Classic Hunter is also a good option if you want the a repeater. Try H4350 or RL-19 if you have any.
