Centrefire,
Let's not get into your familiar online 'showdown'. Neck thickness is a non-issue when you are measuring the difference between before and after seating.
Rock hard (hardened) brass has less springback than fresh brass. It does not have the ductility to grip the bullet like fresh brass does. The bullet acts as a mandrel and swages the neck when seated but is then held with less grip than fresh brass.
Cs,
Feel free to continue measuring OD. You can use Centrefire's technique or mine; they measure the same thing.
