I am measuring on the necks first before bullet seating, they are running less than .001" of runout.
Once the bullets are seated, the necks are running .005" or more and the bullets are running above .005" measured on the nose.
I have not measured neck thickness.
I have not turned the necks.
This is happening with fired or unfired brass.
The neck tension is set at .0015" under bullet diameter.
The brass has not been annealed. The case mouths have been chamfered.
I am using Nosler 'SHOTS', 50gr SP.
I know these are not the best bullets going, but they are good for the intended purpose of the rifle; long range shooting of foxes under a light.
I am seating the bullets .181" into the neck.
