Thanks for the great replies.

What I've ben reading other places is that people are using a forming die like this

to resize the 221 FB brass.

Then when reloading use a neck sizing die with a .20 bushing to resize the neck without un-doing your fireforming.

Has anyone had success with this? Why would it be necessary to use a full length die?

laportecharlie: were you talking about a set like this:

What about it didn't work for you?

Thanks, Matt.
