I never measured from the tip, only the ojive.
When I straighten up the rounds that were .008 out, they all slid into the chamber without a problem.
Try this some time, take a case and bend the neck until it is out of alignment 8 thous and then seat the bullet. But have the bullet just with in .010 off the lands, then see if the case will go in.
The 06 casings will get the "banana curve" from time to time and the necks start to get a large run-out. This is why I check them regularly on the concentric gage.
I have only had this problem with the '06, but I guess it could happen on other caliber too.
Oh..it's not the die that's causing the run-out on the neck either, have tried 2 different brands, same thing. It's probably in the Neck area that's not right.
