Tuning for temperature change with seating depth

My 6 PPC shoots great at 60 degrees. When the temperature climbs how should I change the seating depth? I'm hoping to do this in lieu of changing the powder charge. So do I move the bullet farther into the lands or seat it deeper into the case with less land engagement?
Thanks !

Don, if you can accept a new guys opinion. Once you find the off lands distance your rifle likes you should be tuning your load by increasing or decreasing your powder. ie, less as the temp increases. VV N-133 powder ref

I asked a very similiar question to a couple of Hall of Fame shooters, with others standing around, and the unanimous decision was, when the setting depth is right, it's right and don't mess with it unless you think the throat has moved and you need to chase it. If you can shoot better during a match by adjust the setting depth, it wasn't right in the first place.
