PV,
If you have the Lee's already why not load a few rounds and see where they sit relative to other dies. This will answer your question with proof.
If you could take four measurements to add to the attached table we can compare across brands what the die is doing and what you need from your die;

What this will do give you the total compression and expansion range of your brass. How thick your brass is at the neck, and what neck tension your bullets are being held. You can compare against two other brands and decide whether to keep the Lee or trade-up.
I prefer Forster without the expander. This configuration works the brass the least of the two brands in the table and imparts the neck tension I need for an auto loader.
Obviously you need to knock the old primer out but unless your brass has been dented badly in the mouth an expander is a nice to have, not a have to have. I've noticed no degradation of accuracy since taking it out.

- Measure the outside neck (OD) of a fired case with calipers.
- Then unscrew the primer stem from the die and size the case (the spent primer will still be in). Measure the OD of the neck again.
- Then screw the stem back in, re-lube the case and size as normal. Measure the OD neck.
- Load a bullet and measure the OD of the neck.
