Re: .223 rem reloading question??
You really don't need to resize at all. If you find the neck tension on the bullets once they are seated again to be lacking, then you will need to use the expander/decapper to increase the neck tension. You may be able to get away with running the case into the die just past the expander without depriming the case and then bring it back out. Give it a try and see what happens.
Im not a complete idiot.... parts are missing
