Sorry about that.
It looks like the dies are open inside until they get to the top for the crimp, if my Lee set in 270 Win are any indication. So the .060" 223 extra length should be all that's needed to overcome, from the Lee manual the base, neck, web, nearly every aspect is the same between the two and the 221 Fireball as well.
I think the spacer should work with the longer case, if the 223 is going to be sticking up an extra .060" in the 222 die then adding the spacer to the shell holder will make it crimp .060 sooner.
Adding the .060 to the 223 die (as per my original suggestion) would have made the die close at .120 above the 222 neck, I must have gotten my numbers and dies all screwed up. I was in the middle of redesigning a safety button for left-hand shooters and had a lot of numbers running through my head, I really should quit posting things in a hurry.
