I used off node with the idea that a group performing well with a poor powder charge will improve with a good powder charge. This has tended to be the case with testing. There is the controversial question of which has a bigger impact: powder or distance to lands. This is a polarizing debate so I will leave that up to individual choice.

Like Dean, I look for higher fill rates of powder. There is a lot of wiggle room when seating a bullet deeper or shallower but one must consider that the brass is just a pressure vessel that is either becoming larger or smaller in volume and factor that in. The pressure increases seen with the bullet nearing the lands, or bullet going deeper into the case can occur very suddenly so this is always a concern when working at the extreme ends of the spectrum. I like to think of it as a "U" shaped curve and try to stay in the bottom middle, away from the edges.
