I'm not convinced that seating bullets near the lands does anything good for accuracy. I've played with it a bit in the past and found that its more of a waste of good bullets and gunpowder than its worth. I Use a OAL guage to figure out what my max length is so I don't mistakenly seat bullets any closer than 0.020" to the lands, I prefer farther away if possible with jacketed bulelts.

Two of my most accurate rifles: a 1903A3 likes cast bullets engraved tight into the rifling, a 1896 mauser that has so much freebore that getting a bullet anywhere near the lands would be impossible.
