22-250 Rem seating depth

Trying to figure out seating depth. How far off the lands do you seat on a 22-250 rem?

I am using a Sinclair seating depth guide and comparator.

Lapua brass length 1.902
Hndy Zmax 55gn full length including tip .811 Ogive .337
Measurement on the guide is 1.636

So adding full lenght bullet .811 and guide 1.636 =2.447 for touching the lands?

At what point is the .337 ogive important?

Also using the Zmax with cannelure, the cannelure is about .04 above the brass neck.

What am I doing wrong?
