I start my load development with the bullet right on the lands and work up the load until I see pressure.
Usually that's where I end load development too but if the results at top speed with the bullet on the lands aren't satisfactory (rarely) then I already know my max charge and I only have one direction to go with bullet seating, deeper.
Makes it simple to not have to mess with powder charges and to go in one direction with bullet seating.
2 edged sword here, when you seat bullets deeper you decrease the effective case capacity raising pressures so while jamming a bullet raises pressures so does deeper seating. Just watch your velocity and pressure indicators and you'll be fine.

It's better to shoot for the moon and hit the fencepost than to shoot for the fencepost and hit the ground!
