Just purchased a new Redding type S full length sizing die.
In the instructions, it says to install the bushing and adjust the decapping rod all the way down until you feel it make contact with the bushing, then back the rod off 1/16 of a turn to give you .003-.004 clearance allowing the bushing to self center on your case neck.
If you want to only size part of the neck, back the decapping rod off two or three turns.
Are you better off sizing the entire neck, 25%, 50% or 75% of the neck? Does it really matter? My Wilson neck dies do not let you make the adjustment as to how much of the neck is resized.
