I test all new bullet/powder/rifle combinations with the Berger seating depth test before I start powder testing. I use that seating depth for powder charge testing. Once I find the node I want to shoot, I will test again in smaller steps on each side to see if the group will tighten up some more.
Many times you can pick an arbitrary seating depth to start testing powder charge and find a combination that shoots very good. The problem with that load is that it is usually very sensitive to any changes so you are walking a very narrow line trying to make sure everything is perfect.
