Why would you want a small base die? Unless you are shooting a gun with a minimal match chamber they are not needed.
About all I have are minimal match chambers....
I don't own a SB 223 die. Never have.
I do own a carbide die, adapted to take neck bushings so you don't have to lube at all, but over the years I never use it that much. But if you don't have neck bushings in your carbide die, be aware you still have to lube brass...
