When I had 6.5 Creedmoor built my smith only had to do minor work to get the lugs to make full contact.
What I don't understand is a lot complaining about the action being one length, but then most will say to built a short action caliber on a long action to set the bullets out further. Also complaints about the trigger guard and magazines could fail, but I have never read anything or seen pics showing a actually failure with either, but everyone loves Pmags. I have had two bolt shrouds crack but that is my only issue out of several T3's.
