Knowing where the lands are a nice to have and not absolutely necessary. Seating depth nodes tend to repeat in increments. In general from 223 to 284 size cases the seating depths repeat every 0.015 inches to 0.030 inches of jump. I generally test every 0.005 and when I find two increments that shoot well I retest with 0.003 increments.
Beware the latest group is not always the best in the wind. Start the flames.
