For shooting in my semi-auto rifles, I just load them so that the last groove is just covered by the case mouth on a case that is trimmed to SAAMI minimum. For the .308s I use in 168gr, this makes their OAL a little under the standard .308 OAL. I really don't know what the distance from the lands are in either my M1A or Win Model 100..................but these shoot really well like this.

Personally, with the 3 grooves on this bullet, I think getting all 3 of those grooves in the case mouth is more important than distance from the lands - as the extra contact with the mouth will improve neck tension on the bullet and give it a straighter start down the bore.
