.222 Remington formed from .223 brass, how to do it?

[zeke mccune]

I tried to do this via using a .222 f.l. die but the necks came out wrinkled. What am I doing wrong? Should I trim the .223 cases to .222 length,1.700” prior to using the .222 f.l. die?

not a productive use of 222 brass...223/5.56 is dirt cheap. try a trade...2 223 for one 222. buy 223 and sell the 222. your time is worth more than this advernture
