Dan has it down pretty well, but I would make one correction or clarification. You are NOT looking for the best groups. You are looking for the 3 loads that when the 3 shots are triangulated, the center of that triangle (POI), is the same or very close. If you look at mine above, you can see the POI for all loads from 39.2 to 40.4 have a fairly consistant triangulated POI. From there, you can do like Dan said and tweek it with COAL and such if you feel like you need to.
I think what this really comes down to, and where we have probably not done a good job of answering your question is in the fact that we don't know what you are loading for. Obviously, if you are a 600 yard match shooter you are going to measure and be meticulous with every load, the OCW is not the way to go. If you are loading up 500 rounds for a PD shoot on the other hand...
