Bart,

Your last point agrees exactly with what Vaughn found. Get the bullet in the lands and it's pretty much overcomes most of the bullet tilt. Some bullets are still not at their overall most accurate there, but when they are not it will be for other reasons, like Berger's experience with their secant ogive VLD's.

That reminds me that Walt Berger opined that the fact moly-coated bullets often showed a very slightly higher ballistic coefficient than their bare counterparts was due to the coating helping the bullet center as it entered the throat, so that it had minimal muzzle yaw and correspondingly slightly lower drag over the first couple hundred yards.
