You can get an undersize expander from Lee for the FL die.

I currently use a Forester FL die, the expander measures .3100 and the case necks have good grip on the bullet. It may be your cases have had a a number or reloads without annealing the necks, this causes about .002 springback after pulling the neck thru the expander and loss of neck tension. Until I started annealing the necks, I used a -.001 expander from Lee.
