What cartridge are you loading for?
If it's a 300WM, you will have to load to magazine length and be happy with that, or play with your seating depth.
I have a Kimber 8400 Classic Select in 300WM and I found the best accuracy was @ 3.390" OAL with 180gr Accubonds, groups ran into an average of .3MOA, the next setting back from that I tried was @ 3.375", with average groups running into just less than .5MOA. All from 4, 5 shot groups @ 300yds.
I don't know why you want to run your bullets .030" from the lands, how do you know this length will work the best?
You have to 'play' with your seating depths to find the sweet spot in any rifle, not just use some 'magical' figure of measurement on how far the bullet is off the lands. Some rifles work great @ .100" off the lands, others work best @ .008" off the lands, you just can't tell until you test it out.
