So can you not size cases with a traditional FL die?

Will report back with terminal performance

Basically you want the case neck flared so the sharp edges doesn't shave the soft lead bullet (no need to flare it too much as it would reduce case life I imagine.) The crimp die then sorts the flare out. A lot of pistol dies comes with an expander as part of the kit.

Trailboss is great stuff
