Start at 5 thou off the lands. Then working from that reduce that in 5 thou increments until you find a decent (sub 1") group. Don't stop at the first decent group, there may be a better one. After finding the best length then tweak the load to make that sub 1" group to be 5 holes touching.

Dave,
Some bullets just will not work in a particular rifle.
I must have tried 30 different bullets in my .223 and some of them will make tiny clusters all day long, but some just will not settle down, no matter what.
I found the same bullet issue with my .308 staking rifle only without the objective of making tiny clusters.
DEFINITELY .2 or .3 increments. SORRY(and thanks). Post edited.
I agree re bullets and found Sierra 1360 best in my 22-250
