This will help keep the expander from sticking in the necks.
Ok so providing the virgin brass will chamber in my gun (when its done) i should just adjust the die out so it doesn't bump the shoulder and with no bushing inside just so the expander will open them up and then measure the loaded rounds for the bushing for next time?

Yes it does

Im what circumstances would i NOT want the expander? It would seem that even when neck sizing that the expander would ensure everything stayed round incase the cases were dinged up after ejection. I was wondering why they gave me that extra sleeve when i opened the box.
