The 9mm won't work because it's a tapered case. You'll need the correct die.

If you aren't getting proper next tension, then you'll need an undersized sizing die. I ran into this problem when trying to load .355 bullets.

I stopped using the Lee FCD on auto pistol cartridges, if the neck tension is fine, then that will hold the bullet. I do see some uses, though:

- For revolvers cartridges and rifle cartridges, it's great for crimping in a separate step.

- Some sizing dies won't size far enough down the case. Dillon dies are like that by design, it helps the machine work more smoothly. A FCD in the last stage could be used to post size the occasional odd sized round. My solution was to switch to Lee dies, which size further down the case.
