I load up a some rounds and they are seated just jambing into the lands. I then head to the range with my gear which includes a 21st Century arbor press and a Wilson seating die.
Fire 3 rounds and start looking at groups. After 3 rounds are fired is use the seating die and seat 3 more about 10-15 thousands deeper. I continue checking the groups until I get the groups I'm looking for.
