Brass Thicker at Base with many Makes

Q. I have your 223 Rem Ultra Micrometer die. I full length sized new Lake City 5.56 brass and noticed that about ¼ inch of the brass in not being resized. The area I’m referring to is just above the case head where the case body starts. Is this normal? I’m new at reloading so I want to be sure that I have the sizing die set up correctly. I did set the die according to the directions.

A. Yes, this is normal for many makes of brass. The brass is thicker at the base. It does not expand like the rest of the case.
