I have always fascinated by the focus on bullet jump, and loading close to the lands.
As a swedish reloader, and with experience mainly from 6.5x55 swede, i would tell you that unless you make a custom rifle you will not be able to load close to lands with most, if not all, 130-140 grain bullets.
And that has never been a issue with this particular caliber, as we have been using it for competition for over a 100 years now.
For instance, golden target 130 grain, a VLD bullet many have experience with as i think berger has the same bullet (norma). I load it at 77.5mm COAL and i hit lands at around 82mm.
I have 0 neck grip then.
What gives me better results, regarding even velocities and accuracy, is bullet grip. a well accepted and well tried recommendation is 6-6.5mm of bullet seating depth. Anything more then that just reduce charge weights.
The closes bullet i have been able to get to the lands are the ELD-M 147, and it still had a fair bit of jump. I managed 25mm over 25 shots at 100 meters, that might not sound impressive but the best bench rest shooter that day had 18mm. And this with a Sauer 101 made for huting and 56cm barrel (v0 around 720msec).
