I'm trying to dial in the seating depth for 107gr Sierra MKs in my 6BR. It has an 8 twist McGowen barrel
and I'm using 30.0gr of Varget. Shooting two five shot groups jammed in the lands I got perfectly horizontal tight strings. Shooting two five shot groups .010 off the lands I got perfectly vertical tight strings. This may be a stupid question but if I split the difference and load .005 off the land should the horizontal and vertical stringing come together and me give one nice little hole?
