9-Point, what I usually do is pick the bullet that best suits my needs and try various powders to see what the potential is of that bullet in my rifle. I recently did this with a 300 WM. I used 180 Accubonds and 180 Scirroco's. In the beginning I couldn't get any decent groups with two different powders but I knew the Accubonds had a good reputation for their accuracy. I then tried some H-4350 and immediately found sub 1/2" groups at 100 yds. My first two choices in powder were RL-22 and H-4831, and these powders have always worked well for me in the past. In this case, it was my third choice but it hit a home run.
I usually don't worry too much about sighting in at this stage. As long as it is on paper, I am looking for groups along with Chronographing every shot to see how consistant of a load it is and whether or not it has good potential.
There are also many other things you may end up doing. Different bullet styles, seating depths, primers, 300 yd groups, etc.
This will get you started and other members will chime in with their experience.
