I have seen this before and don't understand what it means: "in the lands"
In my conception of distance of bullet to lands you are either touching the lands, in which case the bullet can't be moved any further forward, or you are "off the lands", meaning the distance from the lands to the the part of the bullet ogive that would touch the lands if you pushed it forward til it stops.
I use a Hornady OAL guage to determine the OAL required to touch the lands for a given bullet. Once I have the "touching length", I back it off as much as I want until I find an optimum length for accuracy.
Am I missing something here?
