Ive never used one of these dies and i'm not sure how to set it up properly being a luddite this fancy stuff is beyond me.
How do I set it up, simple please

Ive pulled the die down and there is a stainless sleeve stamped 221 rem B neck, is this the bushing?
Appreciate any help
Ahh found a picture of the internals it seems the brass bush is missing, I guess they would come in a set for 22 cal
