oooppss....I was thinking you had the Full length die....I would remove the expander button/ball from the de-capping assy...if you have the rite size bushing there is no need for the xepander ball...it may cause the neck tension to be less than you desire....because no matter what bushing you use it will make the neck bak to the size of the expaner.....the die set comes with a replacement de-caping pin holder...use it...
