How do you guys work up a COL, to get your bullet kissing the lands.... Thanks
Kissing the lands will not guarantee accuracy.
OAL should be set by first determining the shape of the groups. The initial OAL does not matter. If the group is a large equilateral triangle, seat out further in 1/4 turn increments. If the group puts 2 together and the 3rd out there, seat deeper in the reverse method.
The only obstacle to this method is where an internal magazine dimension prohibits increasing OAL for scenario one.
