I use to stress and pull my hair out working with seating depth. Now a days i always start at 0.010 off the lands and i've found that i can usually find a very accurate load by juggling powder and components and just leaving the seating depth at 0.010. The only exception I've had was working with Barnes bullets which were seated 0.050 off the lands and wouldn't shoot worth a darn any closer. Works for me.
