I use a generic seating depth of .010" off the lands for bolt actions and maximum listed COAL for semi-autos. Once I have obtianed a good load I then adjust the depth in increments and test them. Almost always end up within .005 of the original .010 off if not .010". thats the figure I find that works best in most rifles.

Semi autos are different. I have found they sometimes like the bullets waaaay off the lands to shoot well.
