How is everybody making the new Rem 17 Fireball brass since there is none avalible yeat? Can you just run 221 fireball brass though the 17 Fireball die or do you need to run it through a 20 cal die first. Thanks in advance.

in making some 17 rem cases a while back I sized them in a 222 mag FL die with the expander nipple pulled out, and then in the 17 die & it worked pretty good.
