handi... we are looking at this from two different points of views.

I know of exactly 0 companies that say loading and seating into the lands is acceptable. Loading into the lands is improper and wrong, so to use that as a starting point is fallacous. You're comment was stated as an absolute (no caveats), and I felt that it was misleading to people who don't reload. Yes, backing your rounds off the lands, like they are supposed to be will reduce chamber pressure.. but to fire a round that was in contact with the lands before ignition is wrong to begin with.

My argument isnt that backing a round off the lands raises pressure.. its that seating deeper raises pressures when all else is right.. aka.. the bullet is already off the lands. If the bullet is .002 off the lands, and you seat it to .004, you will see a measureable increase in chamber pressure in a test barrel. That is the reason some companies put a minimum OAL for specific bullets.
